Lost in Space flattietj,
If your uncle only has a 1" BL on his Rubicon, I think 33x10.5's is really pushing it. Did he add extended bump stops to limit up travel? Not doubting you, just wondering. What is he using for backspacing on his wheels?

flattietj one of my uncles runs a 02 rubicon with a 1"bl and 33x10.5 mts with no rub at full flex and full lock.........i think it is doable for u

Triple88a although they are thinner, they are large in diameter. When you turn fully, they might rub the control arms.


This image is from a cherokee but it shows the concept.. (tjs lower control arm setup is similar)

235/90r15 should be the same height as 235/85r16

Well....I haven't bought 'em yet. But, they won't fit my stock 15" wheels, since they are a 16" tire. Also, I'm a little confused as why a narrower tire would rub?

Mooseman Hey Triple88a, thanks for your input. What 15" tire size will give me the same overall measurements? I would rather keep my 15" wheels and save a few bucks.

like i said, 31.5 tall and 9.3 wide

also is there a chance we can change your mind from 16 to 15" rims?
They are much cheaper, you get some extra sidewall flex if you air down and they look much better.


At last yes i was talking about articulation.. a 2" total lift would be perfect for those tires. You say you have a 1" budged boost lift? add another in body and be happy

Thanks for your help, SocialD. I love the look that 31x10.50's give a jeep, but clearance for chains is my concern. The 235/85/R16's are tall tires, but they're still narrow enough to allow me to chain-up when I need to.

Jma20a, I'm thinking you're right! For some reason I was thinking he was talking about sidewall flex. But he is correct in saying that with the tall tire I will lose some articulation without rubbing.

Mooseman I forgot to say that they are 10 ply tires...so flex is minimal. If they had a less stout sidewall, I would be leary of that much tire between the wheel and ground. I've been running these (10 ply only...load range E) on my old hunting truck for years with no problems and I love the added ground clearance and the added sidewall puncture resistance. You brought up a good point though, it will affect handling somewhat.

Triple88a about 31.5" tire.. and 9.3" wide..

also are you planning on running something bigger in the future?

Another Tire Size Question

I've got a 2006 Sport and was thinking of replacing my 30x9.50/R15's with 16 inch wheels and 235/85/R16's. With no lift other than 1" spacers on the front, will this cause any problems? I'm looking for a tall, but "not so wide" tire....they seem to work well up here in Wyoming snow. Also, what width of wheel?...7" or 8"? Just wondering if anyone has used this set-up. Any input is greatly appreciated. Thanks.

Mike
