And if I run a 285/70-17 it may or may not rub on the airdam or swaybar at full turn. WOW what a big learning curve from dirt bikes.:doh::facepalm:
Correct, a 17x8.5 with a -6mm offset = 4.5" backspace. Also, a 17x9 with a -12mm offset = 4.5" backspace.
Tires are like shoes, some run larger than others even though they may be listed as the same size. 285/70R17 on a 17x8.5 with a 4.5" backspace shouldn't have a rubbing issues, if it does it will be minor. A 2.5" leveling kit or mini lift would clear that up completely and give you a little more ground clearance. :thumb: Give us a ring if we can help you more. We'd love to earn your business.
Anyone reading this that would like help, feel free to call TC at 1.888.459.4080 ext 51826 if you'd like to speak with a fellow JK owner. TC has a lifted 2010 JKU with 37" wheels and tires and a mess of other upgrades. He knows the fitments well and can explain things like TPMS sensor options and tire warranties much better than we can here via PM.
