Replying to: erickpl (Apr 11, 2007 7:59 am) - 5 new 32x11.5 BFG AT's, plus installation - 2.5" OME lift plus installation - Bestop Oversize Tire Carrier - I may try and install myself. I think I'm going with the 32" tires and a 2.5 lift rather than 33"'s. OK - so now one more question about backspacing. It seems like there's 2 was to do it: Either a new rim comes with its own backspacing, or if you stay with the stock rims you do your own backspacing with washers. So, if I'm going from 30x9.5 tires to 32x11.5 tires: - 1. If I stick with my stock rims, what backspacing is needed, and do most tire places agree to do this during the installation of the new tires. - 2. If I buy new rims, I see many come with their "own" backspacing. I'm assuming this means I wouldn't need the washers. What backspacing should I get on a new rim? thanks again for you help, I really appreciate. After this I think I got all my questions answered and will get going on the lift!

Replying to: karlw90 (Apr 12, 2007 6:13 am) Arrgh..................no, no, no, please no!  Go to post #14 (or click here) to understand backspacing. If you want to change backspacing change the wheels or use a properly engineered spacer. Never space out the wheels with washers! The only time washers are used is for limiting the steering travel to prevent tires rubbing at full lock. In that case they're placed behind the steering stops on the knuckles. Check out that post (#14) by Tom, it explains things very clearly.

I'm thinking about going from 215/70/R15's to 31 inch tires. I also was thinking about a 2 inch suspension lift for a more agressive look. 1) Would the susp. lift just be a waste of $$.. 2) Would there be much if any impact with engine sluggishness with the 31"s. 3) Would this scenario mess with drivetrain, create "death wooble" etc. 2002 Wrangler Sport, 4.0, Auto, new to me Jeep! Will be buying new rims and tires.

Replying to: mac24 (Apr 15, 2007 10:30 am) 2: Some, but minimal. 3: Not as long as you plan for the possibility for a motor mount lift (or transfer case drop) if necessary. What mac said, but to expand. 31's should fit with no problem on your stock suspension. BUT, a 2" lift will set you up if you want to go up to 32's down the road. 31's will still look nice with a 2" lift and you'll have lotsa room for flex. It is not a waste as you do get a nicer tire/aggressive look with that lift. You shouldn't have a vibe problem with that lift, but a motor mount lift will really cure that (that is one way to fix the potential problem, and probably the cheapest unless you want to lower the t-case, which seems backwards to me). Death wobble again shouldn't be an issue, but each Jeep is different. If you ensure all steering linkages are secure like they are supposed to be, your tires are well balanced, and your steering geometry is relatively stock, you should be good. -Paul

Replying to: mac24 (Apr 12, 2007 6:32 am) I actually had read Tom's post before, but I mixed up the washer thing for the backspacing instead of the steering stop. After deciding with 32" tires, I'm just going with a 2" lift. I'm assuming that is all I need. Also, after reading Tom's post, and an article on TireRack, I'm still a little confused about backspacing. Assuming the stock rims on the Jeep have 5.5 backspacing (I know I read that somewhere), if I go from 30x9.5 to 32x11.5, does that mean I need an additional 2" of backspacing, meaning I want a rim with 3.5" backspacing? Or do I want 7.5"? Or does it even matter?? Thanks!

Replying to: karlw90 (Apr 16, 2007 5:59 am) 5.5" BS and 32x11.5's will rub when you turn. You can adjust the steering stops by adding washers to THEM, as described at http://www.4x4xplor.com/steerstop.html. Here are the SpiderTrax spacers, as installed on my rear drums:  -Paul |
