So if the wheel width is 7" like you say it is, it should fit with no problem, right?
One more thing...I DO know my physics and know that the wider the tire, the worse it is in snow...but is 225 too wide?? I noticed today at school that the Grand Am GTs come with 225/50/16s on them, and I see a lot of those here in Michigan, so they can't be too bad on those anyway...opinions please!
