im planning on getting some 15" rota wheels, and I was wondering what would be a good low profile tire to go along with it? im also contemplating on some 17's but i don't know...everyone has them and the 15's would be much lighter wouldnt they?

 

what ever tire size you want to put, its best to choose the one that are on or close to your stock tire diameter, so you won't have inaccurate speedo readings.
I guess less than 3% difference is still manageable.
try this site and play around with the sizes

205/55/15 would be a good tire size.

 

I've got a set of 15" Volks w/tires that would look tight on
