hi i just installed a 2.5" leveling kit and got a good deal on a set of tires 325/60/18. i had them installed on my stock wheels and they were rubbing on the a-arms. so what offset,width, and or backspacing do i need for a wheel?

 

325/60 is too wide for a stock rim....I'd recommend a 305 or a 285.....Ask Wandell....He's the bs/tire expert

 

I agree. A 325mm wide tire is too wide for the OEM 7.5 inch wheels. You didn't give any info on your truck, but a ton of members run that size tire on 4x4's with leveling kits with 18x9 inch wheels (4.5 or 5 inches of BS).
