thansk bluetwo... that's some good info...

I just read a bunch of the tech guides at tirerack.com, and they say that wider is not always better in the case of Snow/All-Season tires - the narrower the better... I guess that explains why my current All-Seasons are 185's (and not 195's).

Is it possible that wider is better ONLY for Summer tires?

Another question... I've heard that having a good sidewall is important... but what makes a sidewall good? Does the size of the sidewall make a big difference?
