I'm pretty sure i'm going to get some winterforces for my trans am this winter. I was just wondering if I should get some 245/50/16 or try to get something a little less narraw to do better in the snow. What's the most narrow tire I can fit on a stock t/a wheel?

 

You can go to a 225/55-16 on an 8" wide wheel, if you follow the manufacturer's recommendations. Probably go to 215/60-16 if you wanted to push it. Pick a tire, and look up the manufacturer's recommended wheel width. There is some variation from manufacturer to manufacturer.
