Just purchased a 2018 G63 with factory 20 inch wheels on summer tires. I want to purchase aftermarket 22 inch wheels and run all terrain tires. I have searched the forum and cant find the exact info. Does anyone know what wheel width and offset i would need? What size tire works best with no rubbing or a stuffed look with this setup? Thanks for any help

 

22x10.5, +35 with 33x12.50r22 works, but it might rub a touch at full lock.

 

Would a 10 in wheel take care of rubbing. The height should not be a issue just width correct?

 

20x10.5 Et25 is what the spec was on my Forgestar for my 63 - 305's fit perfectly.... but I'm running 325's now with minimal rubbing ( different rims and using 30mm spacers for time being - they are a 18x9 et 25 with the 30mm spacer effective -5 offset)

The forgestars were light and held up well - and removed need for the heavy spacers ( 14lbs for a full set plus lugs !) - they'll build 22's if you want some rubber band stretchers...

offset is the issue - you need to get tire out to change scrub radius.... a 40-50mm spring spacer is the best way to ensure full clearance, without running into the challenges of quirks the 4" kits can have....

As @Texas E63 said, the offset will be crucial for rub or no rub. A 10" wide wheel might help if the offset remains the same, or goes more positive (effectively bringing the outer edge of the wheel more towards the center). Or, run a shorter tire (BFG are typically short for their listed sizes).
