reason why I ask is because I am gettin 255s in the front and I wanted 315s in the back, but some ppl told me you wont be able to spin them too well if you dont got alot of power, some say I wont be able to lower it and who knows what else, so yes I know 315 is a big meaty bad ass tire so I was wondering what you guys think and if 315 isnt a good idea I was wondering if there is anythin between 275 n 315 if not well i guess 275 will be my back choice. one more thing, if you guys got 255,275,315s on ur stang can you post up some pics of them to make my choice easier and to jus check them out ?
