I've had 265-75-16 load c duratracs for about 15-20k miles so far. They seem to be wearing well. Still lots of tread left.
I have noticed with snow it depends on the type whether they handle well or not. If it's a light fluffy snow then they have terrible traction. If the snow is heavier and the tire can grab then they're alright. Personally I wouldn't consider them a 'great' snow tire. There was literally times when my wife's Acura TSX handled the same conditions better than mine while I was in 4wd.
They cut through deep puddles at high speed very well. They do not have great traction on simple wet roads. I find myself having to be overly cautious going around turns when the roads are wet. It either wants to plow forward or kick the ass end out. From a stop the rear lets loose entirely to easy. I've been in a few precarious situations when I was trying to pull out into an intersection and the tires just wouldn't grab.
Dry conditions they run really well and have good traction. Not horribly noisy, but definitely a noticeable hum. After rotating sometimes they will do the wawa until they've worn a little. They run well on the highway without too much 'loose' feeling from the tread or larger side walls.
Forgot to mention. I don't do any extreme off roading, but I take it up in the mountains and the mud. The duratracs do very well in those conditions. Bite right in.
Overall I'm happy with them. They look really good, handle well under normal conditions, and they're not too noisy. I just wish they had better wet and fluffy snow traction.
They are way better than the BFGoodrich that came stock on my last Tacoma.
When it comes time to buy new tires I may or may not get another set. If I find something that looks as good but is known to handle better, then I will get those.
