We have a stock (I think) TJ and want to move up to some bigger tires. The Jeep spends >90% of the time as a DD, only a few times a year offroad on dirt roads; no trails.
There is about 6" clearance between the top of the back tire & the fender & about 4" in front.
The Jeep has the 30x9.5x15 tires on it now. We'd like to go up to 33x12.5x15 DuraTracs. That's 1.5" taller on top/bottom and 1.5" wider inside/outside. With the proper offset wheels & that much clearance to the fenders, is any lift really necessary for a DD?
We do plan on getting a lift in the next year so we can do some more time offroad, we just can't afford tires (needed now) & a lift.
We could afford some hockey pucks and I'm looking for some really cheap suggestions for beefing up the rear to keep sufficient clearance.
I have Pro Comp 32x11.50x15's on mine with major backspace in the wheels. They are fine with no rub at all onroad. Off road they rub like crazy but just in flex and just the flairs. They seem to give me everything I need to go places people with lots of mods go. The stress on the axel shafts make me leary to go bigger.
From what it sounds like 'round these parts, 33's ideally require heavier axle shafts than what the TJ came with. You'd be smart to upgrade to a D44 as well as re-gear to 4.10+ as the heavier larger wheels will make 5th feel worthless. Tho InfernoGirl (and a few others) don't seem to have done this (if her profile is up to date) she'd be a good source for info - search through her posts.
'course, correct me if I'm wrong guys. I've been reading a lot on here concerning this exact same topic. To do 33s "the right way" seems like an expensive endeavor - lift, parts replacement because of lift, new wheels and rubber, D44 and re-gear.
Firstly, thanks to eveybody for their contributions to this thread.
Secondly, I think I'm gonna do something really crazy. Although the wife & I really want the Jeep to have bigger, meatier tires, I think we're only going to go up to 31x10.5x15s.
WHY you ask? A number of reasons.
1) a friend of ours has a YJ with 33x12.5x15s with a 2" body lift. If he puts his doors & top on, his tires rub on all kinds of bumps. Also, another thing we hadn't considered is that the 33s almost rub the front & rear of the wheel well too, not just the top. He says that he wants to add a 2-3" suspension lift to his 2" body lift to make the Jeep more driveable.
2) if we went to the 33s, I'd have to put a minimum 2.5" spacer lift. I don't mind the work & there are a few decent ones out there less than $300. But that's another $300 plus another $15 per tire.
3) We really wanted the 32x11.5x15s. The DuraTracs don't come in that size. The closest thing is their 285x75x16. And those are $60 more per tire!
4) We're getting a set of vintage hot-rod rims that you normally don't see on a Jeep. I think they'll really set our apart from the rest of the herd!
Our quandry now is:
The rims are 15x7. The tire specs for 31x10.5x15 say that rim size range is 7-9". How much taller will the 7" wide rim make these tires? Is it going to create any handling issues mounted on a 7" rim instead of an 8" rim?
Anybody else running 31x10.5x15s on 7" wide rims?
Thanks again for your time reading & responding to this thread!
7" rim is fine for the 10.50 tire. However, the vintage rims may not be upto going off-road so get some spec's on what they can do. Also with the narrow rim off road, you should not have to air down as much to get traction.

Well, we've decided to go with bigger tires now instead of doing it later. We're going with the DuraTrac 285x75 R16s. They're just under 33"x11.5". We're wrapping them around Cragar's 342s and getting a BB since we don't do any serious off-roading.
If we have any rubbing issues, we wanted the Bushwacker pocket flares but for some reason now I can't find the budget flares that are only $250 instead of $450. If we have to spend that much money, We're gonna go with the Bushwaker flat flares. That way, in a few years when we add the 4" LA kit, we'll already have the flares required for that change.
