jtfst10 Are there any downsides to wheel spacers? I have read the entire post twice I have a 2012 unlimited sport i dont want to change rims at this time and they do not make the Dura Trac in the 255/80/17 which according to the 1st post is the largest you can run with out changing wheels or adding spacers. I have seen multiple people say they wont run spacers just curious as to why

Airborne_82 I just bought some Cooper Discoverer A/T3™ LT275/70R18s. I'm hoping they won't rub. The specifications say they are 11.1" in width. Taking the chance to see what happens. I was may just go ahead and get the TeraFlex 2.5" lift to compensate for the rubbing, that is if it happens.

Mine do stick out about an inch. Maybe 1/4 inch of tread and 3/4 inch of sidewall bulge. Disconnected at full flex the articulation causes them to tuck in under the fender. That is also at full turn.

I would say whatever you do have a backup plan, whether that's flat fenders, lift, leveling kit, jigsaw, etc. I came across others who worked with my combo, so I went for it. My backup plan was a small leveling kit to get by until I add a full lift.

kable Well I went to Discount Tire today and they did some price matching for me, and I ordered some Rugged Ridge 17x9" wheels with 4.53" backspacing and BFG KM2s 285/70r17s. My Rubicon so far and I'm hoping to get lucky and they won't rub offroad when I disconnect, but I'm not optimistic.

Saying they do rub, performance wise (on and off road) am I better off with a lift kit, maybe a TaraFlex Performance leveling kit, or some flat fenders? I imagine, the fenders would be better, to keep my center of gravity lower, and with 33" tires the the ground clearance would stay the same, so is there any reason to prefer the lift kit over the flat fenders? Also I have to say I love the stock ride on road with my 2013 Rubicon and it seemed pretty capable in Ouray with the stock 32s, so my instinct is to mess with things as little as possible.

Guys I am having a hard time making a decision, heres my dilemma:

You have 5.2 of BS on a 285 wide tire and it doesnt stick out.
I just came back from Discount Tire and they put on a XD Crank 5" BS on a 275/70/18 tire and it stuck out past the fender probably at least 3/4 of an inch. I would think that with the 275 tire it would stay flush with the fender.
-Also if I go with that size any issues with rubbing?
-If I am understanding this correct 0 offset is 5" BS and -12 offset is 4.5"BS(XD Monsters I was considering) and the 4.5 would be 1/2 an inch further outside the fender than the 0 offset.
-Can anyone offer any insight?
Sorry for all the questions, I just want to get it right. Not everyday I spend 2k on wheels and tires.

Looks to me like at 5.2 backspace they barely fit. With 4.5" backspace, disconnected, the tires would stick out further and maybe rub. I hope I'm wrong cause most of the rims I like have 4.5" of backspace.

Number8 Here are my 285s (5.2 backspace... for the record).

Naturally, that will depend on the width of the tires, but my memory seems to tell me about an inch.

Plenty of folks have pics up in the numerous wheel threads. I'm sure a search will yield the combination of wheels and tires for reference.

As far as inspections, that depends on your state regs and the particular place you get inspected.

In PA, I remember the regulation stating the "tread" needs to be covered. The DuraTrac's tread wraps to the sidewall, so that creates a gray area open to different interpretations.

Thing to remember about the tread sticking out past the fenders is what happens with snow/mud/etc... It gets flung up on the side of your Jeep/door handles. Some forget about that until they have to deal with the mess.

No. With aftermarket wheels having less back spacing (~4.5" inches is what most shoot for), you'll be fine.

AngryRaul Anyone think a 295/70/18 (34.57 in.) will fit without rubbing fender (No Lift, No Off-road)? Have XD wheels with 4.5 in. backspacing? I have seen that the 275/70/18 (33.62 in.) works. Just looking to possibly stretch it without lifting? Thanks in advance.

Anyone running a 5 inch back spacing?

So everything is telling me run a 4.5" back spacing on my 17x9 wheel with a tire that is 285/70/17 or 33x12.5x17. I do not plan to lift my 2014 Willys 2door, but will probably level the rake off of it with coils or spacers after I choose a bumper to go with later on. Problem that I have is my tire dealer guy(and life long friend) is strongly recommending I use a 5inch back spacing. I do not want to do any metal(frame) trimming but have no issues with tweaking the plastic stuff. I know the easy answer is..."slap on some wheel spacers if there is a problem", but I refuse to use those. So basically, is anyone running 33s on 17x9 with a 5inch back spacing on a stock JK and what mods have you made to anything for clearance?
08-27-2014 12:55 PM
lee indy no issues with any of that
08-26-2014 08:38 PM
BigSmooth What about any electrical concerns with tires wider than stock. I have asked my local dealer and they say wider tires are not the issue (i have stock 18 inch rims with 1.5 inch spacers) its the ABS, tire pressure sensors, etc that could get damaged

thanks

this is great info, I've been shopping tires and I'm still between stock wheels or oversized wheels
08-19-2014 08:44 PM
Number8 Love it. The tires are very well proportioned.
08-19-2014 12:50 PM
daving i just made my purchase based on alot of great advice on here, and i went with the 285/75/16 Duratrac with ProComp 7069 series wheels which have 4" BS. they look great, no rubbing, exactly the look i was hoping for, i had 17" wheels and like the look of more rubber. they do stick out a bit further that i hope, but i realize that's due to the 4" BS. (my state frowns upon tires that stick out from the fender) QUESTION: did i overlook any possible issues getting the 4" BS, other than the possible police pull over? I don't feel like 1/2" would make that big of a difference.

I was going to go this route but wanted to keep the Willys wheels so I had to sacrifice and get the 1.5" spacers to run the same tire.

What do u guys think?
Well my 285/7017R's rubbed so take that for what it's worth. If you get new wheels with better backspacing they will fit. But if you flexed even slightly you will rub the fenders and possibly other stuff. You can do a 2- 2.5''lift or cut the fender to stop the rub. If you had 4.5'' backspacing on your wheels to allow you to go full lock on the wheel and just city drove it they will fit though.

4.5 bs should be perfect.

Stock are around 6.75 I believe? I put 285/70R17 on the stock 17'' Rubi wheels and it rubbed at full turn but only at full lock. I installed 1.5'' spacers and all is well now.

Before spacers.
