I'm no expert so maybe someone else can chime in but you still need to know the disk space to determine how Mich of a space you will need as well as how far you can go before fender work is required.

 

My fronts are +38 with same size tire and they seem to have some room before they would hit the fender, at least a few mm, maybe up to 7 or 8mm. Vossen is here in Miami, you should give them a call, I'm sure they would be able to have wheels finished in chrome if that's what you want.

 

Thnks for that info on the spacing. I will try to give vossen a call later on today.

 

The guys at Vossen will be able to answer all your questions and set you up with the best offset. I called them when I was in the market for rims and they're very knowledgeable. I think you'd be safe to go as far as 20x9fr/20x10rr with an around 30 offset.

 

20x10 +30 in the rear will rub, almost certain of that
