Jeepers often want to go to larger tires as they make modifications to their rigs, either for looks, or for enhanced off road capability. Fender well clearance is usually the limiting factor in tire diameter for a Wrangler, and this can be addressed by either adding a body lift, a suspension lift, or both. A body lift raises the body off the frame, thus increasing the size of the wheel opening. A suspension lift raises the frame (and the body along with it, of course) above the axles, making larger wheel openings for the bigger tires. It is not recommended that a body lift of more than one inch be installed on your Jeep. Often, going to larger diameter tires means going to wider tires as well. In some cases, people just want a wider tire, even if they are not going to larger diameter tires. In either case, it is commonly asked. "What is the widest tire that I can put on my Jeep?" This is where wheel backspacing comes into play. For tires of equal width, the backspacing of the wheels being used determines how close to the frame the tire will run. The higher the backspacing, the more the tires are "pulled in" toward the frame, and the lower the backspacing, the further to the outside, away from the frame, the tires will run. The use of tires too wide for the amount of backspacing of the wheels will cause rubbing of the inside sidewalls of the tires on the spring perches in the rear and on the comtrol arms in the front. Most factory wheels that are used on Wranglers have 5.5" of backspacing, which is quite a bit. This much backspacing limits the tires to a maximum width of 10.50" Sometimes, even with 10.50" wide tires, the steering stops must have washers installed on them to prevent tire rub at full turn. That is a very simple thing to do and should not stop a person from going with the 10.50" tires. Backspacing of around 4.0" is good for most tire widths that are commonly used on Jeeps with lifts and larger diameter tires. Take a look at the diagram below. This should clear up the concept of backspacing for you. Please, come to the discussion "Jeep Wrangler," which is the general discussion thread for Jeep Wrangler owners. We have a great time in there talking about our Jeeps and the fun we have with them. We always give new folks a warm welcome. There are over 22,000 posts in there, so SOMEBODY must like it.

Sorry if this is a repeat question, I'm new here. I am wondering if I can fit the 32" Goodrich all-terrain tire on my '99 Sahara. My local tire store claims sure no problem but I am questioning their know-how. Please help

Replying to: erickpl (Feb 16, 2007 5:42 am) Personally, I prefer a narrower tire generally, and if I was going to a 33" I'd consider a 9.50 or 10.50........... but that's just me.

I have a stock 1998 Jeep Wrangler with stock rims and tires. I want to put 33" BF Goodwrench All terrain or Mud on the jeep. My questions are: will they fit on stock rims? What type of lift will i need? and will it still fit into a garage? I was thinking of going with 33x10.5 with 3inch lift. (do i need new rims??)) Either 3inch suspension or Skyjacker 2" Spacer Lift with 1inch body lift.

Replying to: rowland08 (Feb 27, 2007 1:01 pm) 33x10.5's will fit just fine on stock wheels (mine are the 33x12.5" variety). You will need about 3" of total lift to make it happen, so your lift options are good (I like that you are avoiding bigger than 1" on BL). I, along with mac24 and tsjay, run the OME suspension system, which gives ~2.5-3" of lift (I got 3.25), that with the 1" BL looks and rides great, both on and offroad. However, the OME is a bit pricier, but I firmly believe you get what you pay for. I've heard mixed reviews about Skyjacker. Rubicon Express or OME are the only ones I'd consider for a short arm suspension lift. Long arm is another story and a lot more C-Notes. Here's my 97 with the lift, tires, and wheels.  The size is a great compromise for offroad ability and onroad comfort (and being fairly easy to still get in). -Paul |

That looks great. thanks for the tips. Thats how i want mine to look like. After i get the lift and tires, i want to add the front and rear bumpers and warn winch. However will yours fit into a garage or do you know the height clearance on your jeep. i need to have mine still fit into the garage so i need some measurements before i invest the money. thanks
