Advice on tire size - TJ w/stock wheels

My TJ has stock wheels (Canyon) which are 15x8. The previous owner upped the tire size to 31x10.5 on the stock supsension, and I can see where the front tires were rubbing. We've put a 2.5" suspension lift on it, and are about ready to replace tires. I'm not looking to go wider, just thinking about going taller. Would a 33x10.5 be too big for the jeep, and would it be at risk of rubbing?

Looking at BFG M/T's...

Thanks for any opinions offered.

You will either need to add a 1" or 1.25" body lift or do fender mods or at least flare trim plus possibly adding bumpstop or you may rub your fenders/flares at flex. There are ways to fit bigger tires with very little lift but it requires fender mods. See my build thread I fit 33x10.50 with very little lift.

Also the bfg km2 runs small so a 33 is more like 32.

Was told by a guy at Discount that I would need to go to 11.5 wide with 33's but that doesn't fit what I've read elsewhere. Any comments?

There are a couple brands that offer a 33x10.50. The one I run is BFG KM2s. Most 33s are 12.50 wide. The only 11.50 that comes to mind is the BFG AT in a 32" tall tire

The 32x11.5 BFG was what he recommended, but I think he said it was a MT. I will go to the store and see what they say. It may take me a couple of tries to get it figured out. Thanks... and awesome build, by the way... Looks really nice.

Really happy with the look of my new 31x10.5 duratracs with 2.5in RC lift. Looks sharp and leaves room for max range of motion- flex, extend. Not a fan of the "huge tire crammed into small space" look. Defeats the capability of the Jeep, IMHO.

BFG might still make a 32x11.5 MT. I know they used to. And thanks! Getting my axle upgrades done today. D44 rear with Detroit, front TruTrac, 4.56 gears, sye/cv and adjustabe control arms. Now I'm broke haha.

Checked and you can get the BFG KM2 MT in a 32x11.50. It will probably measure out to about 31 installed.

Got the 33's...

You changed your avatar... nice!

We got the 33x10.5's today, and as you can see below, they fit but are pretty tight. Rubs against the front stabilizer at full stop. We're not rock crawlers, so not as worried about full flex... still, don't want something rubbing if it bottoms out on a trail somewhere... looking at getting wheels with a minimal negative offset, but then we're going to get into the issue of the flares. My son wants a body lift, so maybe that's the route to go after the wheels. Or maybe we just take it easy on the steering... did a little playing around and did definitely feel it rubbing when turning hard.

Clean and new...

Looks great! A 1.25" bl should take care of the rubbing. May have to trim a little off the flares but thats easy. I did it on my LJ and then ran some door moulding along the trimmed edge to clean it up.

Looks Great, I have a 1999 TJ and am going with the RC 2.5 but was thinking about going with the 33x12.50 durartracs. I read in the reviews the duratracs run small just wasn't sure about the 12.5 width??

You will be ok on the width if you go with a wheel with 4" or 3.75" back spacing. Not the stock wheel. With 12.50 width tire go with 8" wide wheel

My 31x10.5 duratracs rubbed at full turn. Added one washer to the turn stops and no more rubbing.
