Here is mine. 18 front springs, .5" teraflex spacer in the rear, VDP stubby kit and cut splash guard with 285/70/17 Duratracs. Turned out perfect for me.

I have a 3" zone lift with 285s and I love it. I get the lift but its still getting great mpg (well for a jeep). Just make sure if you get 285s that you get as close to true 33s as you can or you will regret it.

Figured I'd bump this thread to try to make up my mind.
'13 JKUR and going with 2.5" lift (likely AEV) and want to save money and go stock wheels so I'm wondering if I can run 285/70-17 on stock Rubi wheels without spacers. If I have to buy spacers regardless if I go 285 or 315 I will probably just spring for the 315.

Basically on a tight budget and if no spacers and 285's I'd save $200+$300 which is worth it to me right now. If I have to get spacers anyway the $300 savings isn't really worth it. Although, with 285/70's I could probably get by without a procal right? My 265/70-17 km2s are 31.7 and the 285's are 32.8. Does that 1" really equate to much speedo difference?

Doc - I'm running an AEV 2.5 and the 285 GYD on my stock Rubicon Moab wheels on my 2012. I am running spacers but believe without them the airdam may be the only thing that rubs.

I love the way the 285's look on mine and am seriously happy with the DD performance with the 3:73 and a 6 speed. I still average 20.5-21.5 on the highway and the offroad performance is fantastic.

Yeah the problem there would be my air dam is metal not plastic so simply trimming it may be a bit more involved. I have 4.10 gear ratio with the auto. My average mpg is now 16.5 or so but I pretty much only drive 11 miles to work of all stop and go. Rare sustained speed or highway so I figure 16.5 is about the best I'll get. 315's with a contact patch likely 2" or slightly less more then what I have now and being 7lbs heavier then my current KM2's will probably cause lower numbers. The 285s are the same weight as the 265 KM2s and the contact patch is about an inch wider so likely less detriment to fuel efficiency. Maybe I should just save the $300 difference from 315's to 285's which would at least half pay off the AEV tire carrier I wanted to get as well.

Doc - good points. My 285's were able to sit on the stock carrier, but with the increased weight I knew I was getting a bumper with a tire carrier as part of the build. My driving is 54 miles each way daily and 50 of that is all highway at 75.

It articulates extremely well and I have no rubbing even at full stuff.

Anyone know how far the 315/70 duratracs stick out from the edge of the fender with stock rubicon wheels and spidertrax 1.5" spacers? Do the 285's stick out in the same config of stock wheels and spidertrax?

Here are my 285/70 R17 MT/R Kevlars on stock rims with 1.5 Spidertrax spacers. Minimal extension beyond stock flares.

Any chance of a head on shot and a side shot? I'm thinking of that exact setup.

Here's a broadside shot, I'll have to head out and take a full front angle shot later this morning.

Good thread and lots of info!

I've been looking at tires that will SAFELY fit a 7.5" stock Rubi rim and have been so confused on the entire situation.

I have a 2 door 2013 Rubicon [4.10's and auto trans] and (being installed Monday) a 2.5" TF spring lift, AEV geometry correction brackets and Metalcloak adjustable front track bar. I am already (in prep for the lift) running 1.5" Spidertrax wheel spacers. I've been trying to narrow down a tire for a couple weeks keeping my budget in mind. I can't afford to get a tire carrier/bumper at this time so it seems to me that a 285/70/17 is going to be the way to go for me.

Thanks to all who have posted!

Really appreciate this shot. I like how they don't stick out much. I don't really dig the super wide look. I guess I'm a pizza cutter kind of guy. Problem with the 285's is I am just concerned they will look too small on the 2.5" lift although deainecke's rig looks good. Real functional for both on and off road.

Any other 34/35's that are maybe 10-11 inches wide at the tread and not quite as wide as the 315 duratracs. I need a tire that is just as capable in the cold, icy, slushy winter as the summer and still have decent off road performance. Why I fell on the Duratracs but I just wish there was a 34" tire that was as wide as the 285's... in a 17" to fit the stock rims.

This is exactly what I was looking for. I installed the 2/1 leveling kit last weekend and my new wheels are supposed to ship in a little less than 2 weeks.

Just need to decide if I go with the Duratracs or the Nitto Dune Grapplers in the 315 size.

Excellent. I think that looks pretty good. I'll have a bit more wheel gap due to a 2.5" lift and getting about 3-3.25" out of it due to no heavy armor right now but I think it'll still look good. They look good from the front too. Not too skinny, but not wide either.

Hi guys

I have a JK with 2" Mopar lift and was thinking of getting the BF Goodrich A/T 285/70/R17. I go to the desert like once or twice a month, other than that I use my JK on road 90% of the time. Do you guys think its good, or shall I go for something else. And is there any difference between 16 and 17 wheels other than size?

Width of a tire is the first three digits e.g. 285/xx-17, so you should look for 285s with different aspect ratio (the two digits after the "/").

The overall diameter difference between a 285/70 and 285/75 is .9"

A 285/75 17 would be a 34" tire, Toyo Open Country A/T II is available unsure of the winter performance...

For those with the pintlers and the 315s, how much tire sticks outside of the flare and any rub issues?

Mine stuck out about an inch. But they rubbed so added wheel spacers. Now they stick out more but don't rub. This was with a 2.5 inch RK lift.

I don't know if anyone is still following this thread but I thought I would update. The JK has 14 k miles now and the tires are at 3/4 tread left and the lift has broken in and it rides and performs great on and off road. I would like to regear to a 4.11 which would put me back to the same rpm range as stock with 32" tires. If I did not do a lot of highway driving on trips I would go with 4.56"s. Even with the 315"s and 3.73"s it still does well in the mountains high elevation on and off road. I have since added Bushwacker Flat Fenders and the 315"s look a little small for the lift and wheel openings.

Just ordered 17" Pintlers for my 2013 JKU which has a 2" Mopar lift. Am agonizing about the tire choice -- 285/70 or 315/70 Duratracs. Any updates for from your previous posts or new suggestions? This is my daily driver, mostly on road, and I have little children, who already have to work to get in my Jeep. Most concerned about spare tire carrier and then rubbing. Also moderately concerned about gearing with 3.73 and an automatic. All opinions, suggestions and shared experiences welcome.

I can tell you if you go with 285/70-17 you will be happy for exactly one week then they will start looking tiny. I have a 14 jkur with 2" lift and originally got 285/70-17. I was lucky my tire dealer took them back on trade after 2000 miles and I upped it to 285/75-17 which look much better.
