the thing is also a 8" rim wont allow for true contact patch. Only way id be getting 275 to contact fukll would be with a 50 series sidewall. I have 245/45 on a set of 16x7 rims now. They bow a little and theres 1/2" of tread on each side that doesnt really touch the road like my 225/45s do.
believe me, all the drift guys would see me put 215s on 9" rims
