All season tires are useless on snow and ice unless they're brand new. They're OK the first winter, after that it's bad news. On heavier vehicles I run BFGoodrich All Terrain T/A tires year round. They have good siped treads which grip on ice. For the car, studless Blizzaks have been holding up well year round. No abnormal wear so far, and they do fine in the wet, dry, heat, etc. I probably only drive 1-2 days/yr over 90°F though, in a hotter climate they might not be so great.
[edit] obviously this is a tradeoff--I'm trading slightly reduced hot/dry/wet performance for massively increased winter performance. The reduction in summer performance is small enough to not be noticeable, whereas the increase in winter performance is large. On all season tires I would have to chain up a dozen or so times per year, often just to move the car like 3 car lengths out of a parking spot. I've only ever had to put the chains on once with snow tires on the car, and that was bashing through 6" of unplowed crusty icy stuff up a steep driveway.
I dunno about this - I leave my crossclimate 2 aw's on year round and they're pretty fantastic in snow. We had a pretty good winter this year (44" from dec-feb) and they just worked. I didn't go meandering around any mountains on them, mind you, but they're so far ahead of most typical all-season tires it's almost not fair to compare. For -most- lazy people who don't want to swap tires or rims, they seem a better option than leaving true winter tires on year round. Obviously, there are exceptions depending on where you live.
I've got two sets of wheels, and I rotate my tires every oil change, so it's not laziness that's the motivation. Instead, it was that with 2 sets of tires after 7 years of driving both sets still had tons of tread left but were starting to dry rot. I put about 60k miles on the car during those 7 years. So if I can get ~30k miles out of a single set of snows, and use them up within 5 years, that would be a much better use of resources. The cost isn't really a factor either, I just hate wasting stuff.
I've currently got something like 15k mi on the tires and 2.5yr of year round use. They appear to be wearing evenly and normally.
I agree, I have the same problem, that's why I'm sticking with the crossclimates year round also -- we only drive about 5,000 miles per year, so my tires die from age well before they would wear out from mileage.
I assume we're both making approximately the same optimization but you're going for better snow & ice performance at the expense of some summer and wet stopping distance, and neither tradeoff seems obviously wrong depending on our driving situations.
Yeah I would prefer to run something with an actual tread wear rating, as I believe it would spew less microplastic crap into the environment, and I suspect I might pick up 1-2mpg (maybe 5-7% better?) fuel economy with a less aggressive tire. But the winter performance is really important for me, especially on this car which is my winter beater/mile maker--for now, until it dies and donates its engine to a greater cause. The winters here (northern New England, IECC climate zone 6A) are just about as extreme as it gets in the lower 48. The snow tires have the added benefit of being good in mud season. There are lots of dirt roads around here, it helps to be able to drive them without getting bogged in the spring.
