The rubber on them is pretty chunked up, aside from the rears. I just dont want to spend a wad of money on 255/295, if the rear is just going to continue rubbing. The bumps I hit werent even that horrendous for NY roads. So i'm trying to decide on 245/275 or 255/295, unless I can swing 255/285 as an option without issues. Any thoughts on that?
MSUGOGRN runs 295/30 on the rear of his convertible without issue. I would bet its the Cup 2 tires. A little rubbing isn't a big deal - let them go for a while and see if it goes away.

The 245/275 setup would look stretched on 9 and 10 inch wheels.

I wouldn't run 255/285 on an x drive vehicle. Look up the size difference to see what you think, but also remember the rears will wear twice as fast as the fronts, increasing the difference
