My question is what is the max width tire anyone has put on these wheels without rubbing. I can adjust the offset somewhat and stay within the rules.
I used wheel-size.com to look up the numbers but i’d Love some confirmation from someone who has tested fit.
For the fronts it looks like I could get to 265/35 easily and maybe 275/30
I’m thinking 285/35 rear.

Depends on offset and suspension. I run 285/35r19's on the rear, RE11's, that's about as chunky as you can go unless you run a smaller sidewall. 18's shouldn't be a problem
