Haven't really decided what I'll do yet. I was letting the websites decide my tire size and it was consistently 255/70R16, but when I went out there I didn't even realize I only had the 15" wheels . So the the 235/75R15 Michelins are only $140/tire versus the $127 Firestones. The 255s were $180 versus $139. So I'll probably go with the best winter all-weather highway tire and not worry about the $50 difference unless I decide the Firestones aren't much different form the Michelins. It's hard to make out much from online reviews.
