I'm going to be buying a snow tire package for the winter time here in CO- do I need to buy an extra set of TPMS sensors for the new steelies? I assume no harm will be done (aside from having a lack of tire pressure info inside the vehicle), but haven't seen this question. Thanks-

u dont need them, you'll see the tire warning light on the dash, but thats all. I bought some snows and didn't bother either.

What size 17" rim would fit w/ snowtires? I know the SS comes w/ 18's, but I'm thinking of getting a set of 17's for the winters.

Later
