alright, i'm almost positive i have 245/50-16, tirerack.com also gave me that size, but they didnt they have any winter tires for that size. my question is, does anyone make a winter tire to fit my rim or do i also need to get a different size rim? i have a 2001 trans am with factory 16'' polished chrome rims.

 

225/55/16? You want narrower for the winter. That's a popular snow tire size, tons of choices.
