I have an 06 nissan frontier that I had the day they brought it down off the car carrier. I've had several sets of tires on this vehicle including studded snow tires. To date, my michelin all seasons seem to be the best for side to side confidence however, I do slip and slide a bit going uphill under packed down once plowed snow. IE: slick from being packed down, and still enough snow there to hinder tire > road contact.
I have to imagine there are better tires that I could use during the winter. My last set of winter tires were some continentals that were rated good but to me, the all seasons felt better.
my wife's altima, normally a car known to be good in the snow, SUUUUUUUUUUUUUUUUUUUUCKS in the snow. I put blizzaks on there and they sucked. I then put the general brand on there which were top rated, and they were nothing great either. Compare to her all season, they are thousands of times better, but compared to other front wheel drive cars we have had, this is the worst one with or without snow tires in the snow.
I think it's because she has a lower profile (60's) and a wider tire than you would normally get on a front wheel drive sedan. Normally, these are 70's and thinner tires. Brand new tires and the treads just dont seem that deep, even with snow tires. Because of this, I will likely never buy another altima even though they are a good car for the money. I would likely pay the extra for a Subaru next time.
