I'll see in a few years how well they continue to do, but so far I'm happy with the Michelin XPS Traction, a commercial tire.
They come in 235-85-R16, and after finding that my landlord uses them on his trucks, I searched craigslist and found a set.
Unfortunately, they were over 20 years old, but still not dry-rotted at all. Ran them for over a year until I had money for a new set... and the old set still holds air, with no delamination or cracking.
Those are /good/ tires!
They are also retreadable, which might explain the extra quality materials in the tire.
The new set, I've had for about a year(and 7-10K), and while the tread height isn't as much as it was new, there's still plenty, and they handle nicely. No uneven wear(despite the Dana 50 TTB setup), no rotations done in this time.
Pretty happy so far, and as long as the tread holds up, I'll buy them again.
Also, oddly enough, they are /quiet/. I've run some OpenCountry(?) tires, which you could easily hear as a 'tire noise' when going down the road. These(old and new sets) are quiet. I don't hear any 'noise' from the tires, aside from rocks embedded in the tread 'ticking' until they fall out.
