moparmatt Posted September 17, 2008 Share Posted September 17, 2008 I got some coin saved up and I am going to get some Cragar D windows 15x8 5on4.5. I will end up with a 33 12.5x15. I like the wide tire look on XJ/MJ. Will 4.75" of BS work on my MJ I am lifted about 6". Does anyone else run 4.75" with out any problems? TIA Link to comment Share on other sites More sharing options...
LEAD_NOT_FOLLOW Posted September 17, 2008 Share Posted September 17, 2008 If you want "wide tire look" you want to go with a lower number backspacing. I would go with a 4" or 3.75" backspacing with a 12.5" wide tire. I don't recall off the top of my head what BS the D-Window's are available in, but it should be either 4" or 3.75". For reference here is some pics (tried to find the best one's I had to show stance). My XJ with 35x12.5x15 with 3.75" BS (ignore wife's XJ, she was only running 31's in that pic) My Wife's XJ with 33x12.5x15 with 4.0" BS. Link to comment Share on other sites More sharing options...
89eliminator Posted September 17, 2008 Share Posted September 17, 2008 My Wife's XJ with 33x12.5x14 with 4.0" BS. 14in rims, haha. i do agree with Adam though. I'm running 3.75in backspacing with my 33x10.5s and 6.5in lift. this is the best pic i could find. they stick out at most an 1in past the flare.

moparmatt Posted September 17, 2008 Author Share Posted September 17, 2008 I know I want to be able to air down so 15x8 would be a must. It looks like my only two options are 4" and 4.75". Looks like I am going with 4" Thanks Link to comment Share on other sites More sharing options...

Stock backspacing is 5.25". Rims are 7" and on OEM rims a 30x9.50 rubs on the lower control arms. With 15x8s, you will move the centerline of the RIM outboard by 1/2" due to the extra inch of rim width, and another 1/2" due to the reduced backspacing. The tire you want to run is 3" wider than a 30x9.50 ... which means 1.5" wider to each side of the rim. Your choice moved everything out 1" and added 1-1/2" on the inboard side. It'll rub worse than the 30x9.50s on stock rims. You need to get down to around 4" of backspacing. Link to comment Share on other sites More sharing options...
mvusse Posted September 17, 2008 Share Posted September 17, 2008 Wade, why'd you get my Geo out of the J-Y and tow it to your place? And sorry for the hijack. Link to comment Share on other sites More sharing options...
