MrBigBirdMK Posted September 12, 2010 Share Posted September 12, 2010 I recently purchased an 86 Comanche. I need new tires on it and was wondering if any one could tell me how big i can fit on the truck with out lifting it? I would like to put 31 or 32 inch tires on it. Thanks for any input.

Eagle Posted September 12, 2010 Share Posted September 12, 2010 On stock Jeep rims, 31x10.50-15 is the largest with no lift. They will rub slightly on the lower control arms in sharp turns. 30x9.50-15 is a better compromise for a stock MJ, but they still probably rub the LCAs a little.

jpdocdave Posted September 12, 2010 Share Posted September 12, 2010 imo 31 is too big, I had 30" mud terrains on mine and they rubbed at full turn only in one direction, but they looked good. Link to comment Share on other sites More sharing options...
JACKED88 Posted September 12, 2010 Share Posted September 12, 2010 they rubbed at full turn only in one direction, :hijack: Whats up with that??? Tires that rub but only while turning one direction. I'm only running 33's with a 6+ inch lift and I've checked and triple checked my axle and made sure it and my steering were both centered but it still rubs the lower arm at full left lock. :dunno: Link to comment Share on other sites More sharing options...
jpdocdave Posted September 12, 2010 Share Posted September 12, 2010 probably something to do with the weight of the driver in it, and how the suspension wears. It isn't an indication of anything being wrong. Link to comment Share on other sites More sharing options...
Eagle Posted September 12, 2010 Share Posted September 12, 2010 :hijack: Whats up with that??? Tires that rub but only while turning one direction. On my '88 Cherokee I'm running a '92 XJ track bar. I could not see or measure any difference in length, but it offset the axle a fraction of an inch so it rubs turning one way but not the other with 235/75-15s on. With 31x10.50s on it rubs both ways.

Pete M Posted September 15, 2010 Share Posted September 15, 2010 an easy cure for tire rub is to adjust the steering stops. :thumbsup: a better way is to swap in WJ lower control arms. 31s on Jeep rims with WJ arms and no rubbing on the street: Link to comment Share on other sites More sharing options...
jimoshel Posted September 15, 2010 Share Posted September 15, 2010 Just looked at a 1989 XJ with 31.50X10.50X15 on stock rims. No lift. There is a a small rub mark on the right hand LCA and a just barely noticeable rub mark on the left LCA. No marks on tires. From what I saw I'm not going to worry about it. If I wanted to do something about it I believe I would just heat the small rib a little and hammer it up next to the main part. Another idea would be to cut a arc out of the bottom side of the LCA. If there was any worry about weakening it then weld a piece in the bottom, closing the 'U'. Link to comment Share on other sites More sharing options...
