since the truck is gone, and genny has about 5 seasons on the snows, the rears are a little low. If i had the truck, i would have just went this season on them. Since it's gone, i need a good rear tire with tread. I have the birdgestone blizzack lm-60's on it now, but apparently those are no longer being made. The lm-32's that replaced them seem to be less of a die hard snow tire, focusing more on dry traction/stability-- exactly what i don't want (i think the lm-60's are fine). So, dad didn't know what to get me for Xmass, so bingo, thanks dad! had him order me up a set of the Michelin Pilot Aplin PA4 to try for the rears. my front lm-60's are still 80% tread life, so it won't be too far off of a match on the set. Anyway, On the receipt from tire rack, it says WTF is this? is this a new law? http://www.tirerack.com/tires/tiretech/techpage.jsp?techid=171 This is news to me.. first i've seen of it. Are you guys aware of this and i'm just oblivious?
