If you're mostly in snow I'd go higher psi, but if you're mostly on ice I would run a lower psi.
Our Michelin Xi3s actually aren't terrible on fuel. Somehow they managed to make it an LRR tire - yet be one of the best snow tires out there. Guess that's why you pay a premium for them.Winter tires are lousy on fuel economy. They're designed to stick as much as possible, which significantly increases rolling resistance. Keep them near the sidewall MAX PSI until you get snow or ice, then lower them to the door placard for extra traction.
Tire Rack would beg to differ. They only rank the Blizzak WS80 better - and it just came out recently.Junk I declare!
Tire rack testing as well as their user reviews are for brand new tires. I've found that even a slightly worn tire will not hold up to their claimed numbers. I've purchased tires they claimed where good as well as had very good user reviews, and not been happy for long.Tire Rack would beg to differ.
