I run a +40mm offest on my 8.5" wides and a 245 wide tire and my tire sits even with the fenderwell, a +35 will stick out a tad and may rub if you lower it. +38 to +45 is the best range imo.
My issue was We ordered some wheels for my E and they decided to send us a+15 instead of a +40. Well for $hits and giggles I thought I would give it a shot since they were mounted and balanced. To say the least I was riding dirty, real dirty. I do not see it working out. The best part about it is the company sent the wrong offset because "that was all they had" in that style. nice huh?? :twisted:
