I have black 2000 xj with a 2" rough country lift. Last night I ordered a set of cragar 310s and dick cepek 30x9.50r15. After sleepin on it I realized I ordered 15x7's instead of 15x8's. I call quadratech but they already shipped. Will I notice much of a difference? Does anyone have any knowledge on the topic? Thank you

 

Recommended mounting width should be somewhere around 6.5-8.5" so you should be fine as long as you don't air down to single digit PSI. Many run 31x10.5 on a 7" wheel.

Edit: Here's the only DC tires I see in 30x9.5, yup, 6.8-8.5. You're good.

Awesome thank you! Kinda new to all this. So as long as the rim width us witching that range it doesn't really matter? I just didn't kno if it'd have an affect on the tire stance

 

The tire will look a little fatter but that's really about it.
