need help choosing a rear wheel size and offset..

Wheels will be work vs-xx's

18x9 +58 or 18x9.5 +52? I am lowered with Skunk 2 Pro COilovers, Rear Quarters are rolled.. Would there be issues of rubbing witht he 9.5? I think the 9 would be fine..

Front will be 18x8 +58 which is fine..

 

Well I think both would be fine, but even without fender rolling, with the 9's offset you could safely fit 265s, with the 9.5s offset you could only fit 255s. But, since you have your fenders rolled, you probably could put 265s on the 9.5s also.

 

I agree, the offset is high enough so you should not have an issue. If you want to be safe go with the higher offset and the 18X9.
If I can help with the tires let me know.
