This might be just beating a dead horse post as I'm sure people have asked this before. Two questions.

One, has anyone ran a wider tire on the back of their cars with the stock wheels? I have Factory Roush 20's. I think they're 9.5" in width(might be mistaken). I'm wanting to run a drag radial and keep the look of the stock wheels. I really don't want to run another wheel...

And two, does anyone happen to know how heavy they are? Maybe a dumb question since I want to keep the stock wheels, I'm just curious.
