Just remember this even though a tire can go on a rim the "look" will differ with the width of the rim. So if you slap a 275 on a 9 inch rim it will probably bubble out a bit vs on a 10.5 inch rim it would stretch a little.

I rocked the 245/275 set up on my 350z with the stock track rims and the rear bubbled a bit more then I liked but was still ok for the rim width.
