I'm having some trouble finding any tires in the 21" 245/35/21 265/35/21 range that do not have the giant "DO NOT USE BELOW 45 DEGREES WE WILL NOT REPAIR THEM THEY WILL CATCH FIRE AND YOU WILL DIE" warnings. What are you guys running and how has that gone? I live in the PNW with mild-ish winters but we definitely have a few weeks of freezing and a few months near it. I REALLY don't want to have to buy another set of wheels just for rubber! I've looked at tirerack at the Pirelli PZeros and the ContiSport Contact 5Ps. I would love to sacrifice some 'ultimate summer performance' for tire longevity and all season use! Any suggestions?
