A question for the Jeep CJ-8 production history buffs. From what I know the Scrambler was only produced with narrow trac axles during the first year of production in 1981(also used on pre '81 model CJ's). That same year was the last year that they made the 15x8 wheels and the only year that they made the 15x8 wheels with center caps. So it seems to reason that the 15x8 wheels were designed to work well with the narrow trac axles. That being said, from what I can tell and what I have read the 15x8 wheels have more back spacing than the 15x7 OEM wheels. If the 15x8 have more back spacing, would that not just exacerbate the issue of tires rubbing the frame or leaf springs? I guess my question is why did AMC decide to offer wheels with more back spacing on the narrow trac axles? Did the 15x8's just help with a wider stance on the narrow tracs? Was back spacing never really an issue because the stock tires didn't have any issues with rubbing? Is any of my information wrong? Is anyone running 15x8 OEM wheels with narrow trac axles with larger than stock tires and not have problems with tires rubbing on the leaf springs? Anyone running 15x8's on narrow tracs and is having a problem with rubbing?
