Unfortunately I can't help you with the snow traction question. I've only had the tires on for 2 weeks. These are nice looking tires and they look good on the Tundra. It's hard to say for sure, but I think these tires are a little stiffer riding than my previous Goodyear Wrangler RT/S. I'm disappointed with that 'cause if you read the comparisons on the
tire rack's chart, the Yokos should be far superior. I've always had a vibration in my truck which I thought was caused by the Goodyears. Well now I have new wheels and new tires and still have a vibration. I'm supposed to go and get the tires checked by a local tire shop.
I was going to get the Michelin M/S but got swayed by the price and the
tire rack's comparison chart. I'm thinking now maybe I should have got the Michelins. It's hard to say if that would have been a better choice or not.
