I'm currently looking to buy a set of 18x10.5/18x9.5 wheels in the near future and i wanted to know if i can go past a 245F/275R tires without having to roll the fenders. I would love to run a set of 295's in the rear if its possible without fender rolling. The car will be dropped ~1 inch and the wheels will probably have an offset of of around +20. I ran a search for this and i came up with nothing.

 

it depends on the tire. I had T1S's on my car (275/40), and just swapped to S03's and now I have some slight rear rubbing (passenger side more than drivers). My car quite a bit more lowered than yours but to be safe, I will be rolling fenders this weekend

 

I'd have to say that more than likely, you'll rub with the 295s. There's a guy on g35driver.com that had 10.5 w/ 295s lowered and he rubbed.

BTW, I have 19x9.5F w/ 255/35/19 & 19x10.5R w/ 275/35/19 (+20 offset front and rear). I can go 285/35/19 in the rear but only a few tire companies make that size.
