Tire Question

Hello guys, new Jeeper here! Just took delivery of my brand new 2018 Wrangler Sport JK 2 door today and loving it. It's completely different than anything I've ever had so I am liking the novelty factor.

Always wanted to have a Jeep with big tires etc., that looked aggressive and now I finally see myself getting close to one of my goals. My question related to the kind of tires and rims I should look at.

Basically, I don't want to do anything to the vehicle that voids the warranty. So I am trying not to think about the levelling kits or lift kits etc. (not quite sure what the difference is to begin with as I don't really have any technical knowledge when it comes to Jeep's). Anyway, I was told by my sales guy that as long as I don't do anything that messes with the suspension the warranty won't be voided but I guess let's just say that I don't want to take any risks.

So what I am thinking is, what is the biggest size of tires and rims can I go with that would work with the Jeep without me having to get it lifted/levelled? 31" tires or 33" tires? What size of rims? Of course I'd like to avoid any sort of rubbing issues or problems otherwise. I don't quite plan to take the vehicle off-roading, at least not yet, so I'd rather get something that's somewhat comfortable as a daily and some sort of tire that works good enough in winter with snow also.

The look I'd like is just the big mud/snow tires that makes the Jeep look aggressive, on black rims that stick out from the sides. The stock tires are Goodyear Wrangler with 17" rims and while it's not a bad looking combo, I really want something noticeably more aggressive.

I am sure this is one of the more common questions and I have been doing quite a bit of research and watching Youtube videos - so I am getting somewhat of an idea, however, would like to hear from actual people that are doing this to their Jeep's. If some others out there actually have this setup (stock everything w/ bigger tires), then please do share the pics as well.

Thank you Wrangler community very much, I look forward to enjoying my Jeep for years to come and slowly make it my own!

If you make a change to a vehicle, you only void the warranty on what you changed.

So a suspension lift only affect warranty on those parts you replaced. The dealer can’t deny warranty on the engine or electricals for example.

Regarding tires you can go up to 33” without any suspension change, 35” with a basic lift. A 2” lift and 35’s is “safe” on a JK; you will need spacers or new wheels with less backspacing if getting wider tires.

Thank you for your reply. That makes sense about the warranty. I guess maybe better to wait the 3 years when warranty expires before risking even the suspension component.

What is the difference between the levelling kit and lift kit? I keep seeing references to both and they both appear to do the same thing, i.e., lift the Jeep?

In regards to the biggest possible tire on stock height being 33", I think I would be happy with that for now. What size of rim can I go with that? Or is that my choice? How wide will that tire be? I don't mind getting spacers if I have to, just not sure what kind etc. I wouldn't have mind putting the 33" tires on stock rims (if they fit) but they are silver and I think I need to get a set of black rims so will likely have to buy some new rims as well. So recommendations on the tires (good for summer and winter (snow, cold etc)) and decent rims and spacers that I will need, will be great.

Thanks very much!

I just did this same thing with my Jeep I bought in December. So I feel you. Heard everything as I understand it. Lifts on your Jeep can void other parts of your warranty if the damage can be related to the lift. For instance some lifts don’t have new connectors for the tie rods etc and any damage done as a result is not covered. My brother works for a Jeep service center. Said that you can have the Mopar lift installed by the dealer and that’s covered. In research that was a pretty penny so I decided to skip the lift mod for now.

Lift vs leveling. The Jeep and most cars have a down angle lean towards the front of the car(rake is what I think it’s called). Leveling kits might lift your Jeep overall just a little bit, but have more lift in the front to remove this rake and level the Jeep out. Some kits just lift the whole Jeep overall.

Tires and wheels- I went with 33s A/T3 p285/70 R17. And Fuel Assault Wheels they fit and don’t rub. I also don’t do a lot of off roading. Like none yet but might take it on some light trails someday.

Getting them to stick out depends on tire width and back spacing read this post to learn all about it and the look you want.
https://www.wranglerforum.com/f27/largest-tire-on-stock-jk-heres-your-answer-142837.html

The tires above had no noticeable road noise compared to the stock all season tires I had on it before.
Some notes:
I’ve read a lot about gearing mattering when you get new larger tires. I had no issues. I bought the Bluetooth adapter and app for my phone to update the tire size in computer. And it does fine on the highway and the surface roads. I live in very flat Wichita Kansas so that does factor in. I have 3.21 gears. 70-75 on the highway is fine on really windy days 25mph head winds it does seem to down shift a little more.
If your new tire wheel combo weighs more than 85 pounds you’ll need new hinges and tire carrier.

Lastly here’s a before and after pic of my rig the only mod change was tires and wheels. Makes all the difference in the world to me I had the small 29 tires before on 16 wheels so Really got some height added by the larger tires.
Whew that’s all I know for now 🙂 Good luck!

There are 3 kinds of lifts:

- Body lift. Rubber spacers are inserted between the frame and the Jeep’s body. Can get you 1 or 2 inches in height, can help for larger tires, do nothing for ground clearance (as the frame sits at the same height)
- Spacers. Rubber spacers are inserted above the springs. Leveling kits are in that category. Provide from 1/2” to 1.5” of frame lift. Very warranty-friendly as you’re not replacing any component. Cheap, DIY in your driveway in an hour or two. Your best bet to start, no need to wait. $100 and up.
- Spring lift. Springs and shocks are replaced at the minimum, but can involve replacing the entire suspension and steering systems for more height and off-road capabilities. Cost from $500 up to the GDP of a small country.

Note that Jeep dealerships are usually quite tolerant of basic modifications, the Wrangler is designed to be easily modded and is probably the most often customized vehicle out there.

As for the easiest option for you: look into a set of Rubicon wheels and tires, as folks sell them as they opt for bigger tires. 32” mud tires straight from the factory, just bolt on and go!

A very safe approach would be a Teraflex leveling kit (2” front, 1” rear, $190) and 33” tires on wheels with 4.5” of backspacing.

Aggressive look, good road manners, no warranty issue, easy DIY.

Thank you so very much gents! That's a wealth of knowledge and already puts me so much ahead than I was yesterday. I will compare some pics of 33" inch tires on stock everything else and 33" tires with a minor 2" lift as referenced above to see if the look is that dramatically different and more appealing to me. Based on that I think I will make my decision.

I definitely know that I don't want to go bigger than 33" tires because it's going to a 'pavement princess' for the most part and get driven on highways a lot, so I don't want it to get too comfortable for the sake of cosmetics. The pictures posted above of everything stock with the tires is actually absolutely beautiful and I love that look. Just have to see if I like the 2" Teraflex levelling kit with those same/similar tires any better or what.

The added expense of the 5th spare wheel is also a little silly, but you kind have to get that I guess to complete the look. Haha.

For your reference this is a 275/70r18 with 1 1/2" wheel spacers and no lift. It is a 33" tire

^Looks great from this angle. Do you have any side profile shots from the back to see how much they stick out with the spacers? Thanks.

Also, if I am going with 33" tires in either 17" or 18", how wide of a diameter do I need for the rims they go on to be? 9? 9.5? 10? I don't imagine they would fit on my OEM 17" rims.

Check out the tire specs for approved width. My last tires were Toyo Open Country M/T 285/75R17, i.e. 34". The approved wheel width range was 7.5" to 9.5".

BTW those Toyos are great tires both on the road and off. Their only drawback is weight. Check them out in 295/70R17 (33x11.50)

Also check out Tire Calculator

Thank you will check it out.

Also for fun I am adding some rims and tires on a local Canadian site to see what they'll end up running. It's a set of;

Ion Alloy Style 141 (Gloss Black/Milled Spokes) Wheels 17" x 9" 5/127(5/139.7) 18 87.00

and BFGoodrich All-Terrain T/A KO2 Tires LT305/65R17 121R

But I wonder if these tires would fit on my Jeep without lift and not rub etc or should I stick to the 285 size?

The set of 5 of these with TPMS and necessary bolts etc would run me $3500 Canadian. Plus install, probably under $100.

Or the exact same set up with same tires etc but in 285/70/17's are about $200 cheaper. Over $200 I would rather go with 305's as long as they'll fit without rubbing etc.

I read some good reviews on these tires but will also checkout the Toyo's. This site had those as well so will price out that option once I figure out about the size exactly. Also when looking at pics of tires I was trying to pick more aggressive looking ones because 'regular' ones also seem to show up in the same sizes and then some show up with more aggressive tread pattern etc.

Man that 5th tire/rim sure does add like a grand on top!

^anyone has any ideas on the above? The 285 vs 305 tire issue? Would both fit without rubbing etc on a set of 17” rims? Do I need spacers or anything? The goal is the have the tires sit out an inch or so outside the fenders.

The other thought I am having is since my stock rims are 17” also what’s the point in spending $ on aftermarket 17” rims also. Which brings me to the question, what’s the widest tires I can go on stock rims? I don’t mind doing spacers in order to avoid rubbing etc.

305/65 will be a little wider and just a hair shorter than the 285/70. The wheels you posted look like they are +18 offset. On a 9" wheel, that'll be like 5.75" of backspacing, close to stock. I would not bother with those. The point for most of us when changing wheels is trying to get a wider wheel with shallower backspacing to push the tires out for clearance. Generally, 4-5" is what you want. I would say if you like the look of your stock wheels, just keep them and use some quality hubcentric spacers. Stock wheels are 7.5" which may be out of spec for a lot of the wider tires (12" and over) but it varies by model. Some shops won't care about that and will mount them anyway. 285/70 on stock 17s is a very common combination and is actually the stock set up on JL Rubicons.

This shows how little I know about this stuff. The reason why I was considering 305 was because I thought well 305 is wider than 285 so it automatically would fit farther out then 285. But reading your post, that doesn’t appear to be the case of course.

I do want the wider look where I want the tires to stick outside the fenders for that wide/aggressive stance.

I don’t mind my stock rims even though if I keep them i’d Have to powder coat them or plastidip them black, but the stock tires Good Year Wrangler’s aren’t very aggressive looking. That’s why I’ve narrowed down to BF Goodrich KO2’s even though they are a bit pricier.

What I am trying to figure out is if I go with 305’s it doesn’t sound like they will fit on stock rims, correct? So that’s not going to work.

Second option is 285/70/17 and sounds like that WOULD fit on the stock rims? Do I run this setup as-is or do I use some spacers to stick them out further out and to avoid rubbing issues?

I want to stay away from lifting either by way of levelling kit or coil spacers just because of the fear of the dealer voiding warranty is something happens, but if I do decide to do the coil spacers or levelling kit, then I understand I won’t have to bother with wheel spacers to avoid rubbing correct?

There’s just so much damn into this, I’ve spent two full days I feel like and I am still nowhere ahead, haha. Every time I think I’ve figured it out something else happens and I get confused again lol.

ALL that said and done, now I am considering the new option you suggested! Of simply using some hub centric spacers and pushing my stock rims/tires further out a bit. Obviously would be the cheapest option. I wonder if that setup is what I opt for, what the kind of spacers should I look for? 1”, 2” or more?

With this option I could do hubcentric spacers and push them farther out and also do coil spacers or levelling kit and achieve that for less than the price of 5 new tires I feel like. Goodyear Wrangler just in general isn’t really an aggressive looking tire like some of these other AT and MT tires are so that would be the only thing I got to consider about going this way.

Would going with these spacers with my complete stock setup of wheels and tires (255/17) make any sort of noticeable difference in achieving that aggressive look?

https://www.4wheelparts.ca/Wheels/G2...view_Container

Or should I opt for either a set of aftermarket rims (or stock rims) but throw on the 285/70/17 BF KO2 tires on it and also use the spacers at the same time to make a noticeable difference and also avoid rubbing (by using spacers)?

Just getting started setting up the wife's Wrangler. Here it is on stock suspension (though I'll be doing a Teraflex 1.5" level kit) with 1.25" spacers and 285/70-17 ProComp ATs on 17x9 wheels with -6mm offset. Offroad she'd probably tear off the stock fenders pictured here, but those are long gone (and besides, she doesn't go offroad unless you count parking garages -- as they say in Texas, all hat, no cattle).

The 305 should give about 10mm more 'poke' than the 285 on the same wheel.

The 305/65 KO2 looks like it isn't rated for a 7.5" wheel but people are running 315s on stock wheels, so... It'll depend on how your installer feels about it.

I think any 285 is fine on a stock wheel. You would probably need spacers to not rub, and definitely to get the poke you're looking for.

The typical leveling kit = coil spacers. I don't have any personal experience with warrantying a modded vehicle so I can't comment on that. You probably would still need spacers even you lift. Spacers/backspacing is for clearance behind the tire, lifting is for clearance on top of the tire.

Yep. I spent well over a year researching this stuff before I even owned a jeep and I still have a lot to learn.

Yes, spacers alone with on stock wheels and tires would look better for sure. Those G2 spacers would be fine. Spidertrax are considered the standard. 1.5" is the most commonly used but 1.75" and 1.25" exist also. Aftermarket wheels with spacers is ok too if that's what it takes to get the stance you're looking for. The important thing with spacers is locktite and a torque wrench.

A 2/1 Teraflex leveling kit and 1.75" Spidertrax spacers would be quality and affordable and give you room for 285s or 305s.

The 305/65 KO2 looks like it isn't rated for a 7.5" wheel but people are running 315s on stock wheels, so... It'll depend on how your installer feels about it.
I think any 285 is fine on a stock wheel. You would probably need spacers to not rub, and definitely to get the poke you're looking for.
The typical leveling kit = coil spacers. I don't have any personal experience with warrantying a modded vehicle so I can't comment on that. You probably would still need spacers even you lift. Spacers/backspacing is for clearance behind the tire, lifting is for clearance on top of the tire.
Yep. I spent well over a year researching this stuff before I even owned a jeep and I still have a lot to learn.

Thank you so very much for your reply and answering the exact questions I had.

I think that's what I'd like to do which is stick to my stock rims (later powder coat or plasti dip them) and install the 305 tires on it. Those along with the 1.5" spacers that I posted above should be exactly what I need for the stance I want (tires sticking out of the fenders an inch or so) and also not cause any rubbing issues.

Just installing the spacers on stock rims and tires while may push them out a bit, I am not really sure how far out the 255 tires would go and they certainly won't look 'beefy' like the 305's, so I think I have to invest in some aftermarket BF KO2's for sure for that aggressive look I want.

Going this way I will save (have done the math) about a $1000 over going with aftermarket rims and TPMS. I guess I better just hope that the shop installs the 305 tires on my stock 17" rims I guess cause otherwise I am screwed! Haha.


EDIT: I found the Spidertrax spacers you were mentioning too. If they are better than G2's then I will go with them, they are only slightly more pricier.

https://www.4wheelparts.ca/Wheels/Sp..._pn=SPIWHS010K

The site also have some 1.75" ones in 5 x 5 bolt pattern (which I believe I need) as well in both G2 and Spidertrax. The price difference in each is about $50 a pair. If both brands are equally good I can do one of them in 1.75 if that's going to be better than 1.5"?

What do you suggest with the 305 tires on the stock rims? I want the tires to poke an inch or so but not look cartoony or ridiculous. Thanks.

You can just put a ruler up to the side of your tire to see. The spacers will literally just move the tire over buy the thickness of the spacer, either 1.5 or 1.75. And then you can also estimate where the new tire will sit. The 305 will be roughly an inch further than the 255.

I would check with them before I ordered tires. Also ask if they'll have a problem with the spacers being on there. If they won't touch spacers, wait and you can drive home with the new tires without spacers, just don't turn tightly.

I don't know anything about the G2 but I would think they're fine, G2 is a real brand of drivetrain parts. Spidertrax is just the #1 recommended spacer. It's really just the no name Amazon stuff you need to watch out for. The 1.75 will give you a tiny bit more of the poke you're looking for, so if the price difference is negligible, you might as well. If you're going with the 305/65r17, I would save the lifting for last. Depending on how high your stock springs have you sitting, you may not want to lift at all.


You're welcome, just trying to help out.

For a reference, this is mine. 295/70r17 Cooper STT Pro on a 17x9 with 4.75 backspace. My front axle is off center to the driver side by a tiny bit, half inch at most, maybe only a quarter.

I really appreciate it, thanks for all your help!

I have gone ahead and placed the order. That site I was linking has a local install centre so I am hoping when I go for pickup I can just get them to install. Probably should have checked re: if they'll install the 305 tire on my stock rims I guess, but it's already done. Got sick of researching the shit out of this whole thing, lol.

Worst case scenario, I have an independent shop that would likely do it if the site people won't or EVEN worst case, I will have to order a set of aftermarket wheels that are 9" wide and install the tires on that and return the spacers. The price difference between going with the cheapest 9" aftermarket wheels with 4.5" backspacing and the spacers I got was about $400-$500.

Now that I am thinking about it, if I have to go this route, I could get away with wheels that are 4.75" backspacing (many more options and cheaper) and add a 0.25" spacer and have the exact same setup as having a 4.5" backspacing wheel correct? Damn...perhaps I should have just done that! Haha but then TPMS would add another $200-$300 on top.

I went ahead with the spidertrax 1.75" spacer I linked above just to be on the safe side, they were only $40 more than the G2 1.75" ones. Now the waiting game begins and the anxiety of finding out if the shop will do the install etc. Haha.

Thanks for all the help, will be sure to post pictures up eventually. I do like the idea of waiting on the lift part now as let's see how far up the Jeep will go with this setup and see if I want to do the lifting after. I have never ran spacers before so I hope it's safe to do it as I will be driving on highways a lot etc.

That looks great. When you say, "My front axle is off center to the driver side by a tiny bit, half inch at most, maybe only a quarter," are you saying the tires are rubbing or something?

If I get at least that much of a poke with what I ordered, I will be happy. Slightly more without looking cartoony will also be great. The key would be to make sure everything else can remain stock and the tires don't mess around by rubbing etc.

Which all the math seems to suggest shouldn't be the case since with 1.75" spacers I will have 4.5" of backspace left.

I am running 17 X 9.5 and P285/75.17's with a -12 offset. I have a 2 inch lift. The tires stick out about 3 inches past the fender wells.

For a bogie, I've worked over the last year on mine, varying the amount of front lift, doing tires, doing the spacers. This now has "nearly" no Jeep Rake (about 1/8" still). Rear 1" Terraflex spring spacer. Front is spacer disks I made myself. Total now is 2.25". Note that if a front bumper/winch is added, more front lift will be needed to level it again. These are 295-70-17 Dick Cepek Extreme Country tires which have proven themselves for traction offroad. They're loud as hell on the highway, but I could care less. If I wanted quiet, I'd get a Lexus and bottle of Grey Poupon.

No problem. No, the spacers we're talking about are actually adapters, they bolt on and the wheel bolts to them. They have a minimum thickness, basically the length of the original wheel studs. A spacer that thin would just be a plate with holes in it. A very bad idea.

Thanks. No I don't have any rubbing. When I lifted the jeep, it pulled the axle sideways to the driver side a tiny bit. An adjustable track bar would correct this but it's not noticeable enough for me to worry about at this time. I only mentioned it so you would know that the tire in the pic has a tiny bit more poke than it should have due to the axle being off center. I think you'll be happy with the effect of the 1.75" spacers.

Thanks very much! The waiting game has begun since 2 days ago, haha. I ordered the 305 tires along with 1.75" spacers and now am just waiting for the tires to be shipped to the local 4wheelparts.ca store. Called them today, they have spacers in stock just not the tires.

Also talked about putting 305's on the stock Jeep rims and he didn't seem to think that would be an issue. Have also ordered satin plastidip for the rims and going to see how that looks. I am pretty sure I won't mind the look of the rims like that as I had done that on my X5M a while back and I enjoyed the look.
