First off, they've been an excellent wearing tire, no complaints there. They're a good riding tire especially on bumpy roads. As far as traction goes, they're pretty good. My truck has stability and traction control, plus it's heavy, so it's hard to assess how they are in the real world. My biggest complaint with them is handling. They're kind of mushy and unresponsive. They let the truck sway and fade over way too much for my liking. I can't believe I've driven them this long.
If you have a truck or mid size SUV that needs a decent, long wearing tire, then they are o.k. If you have a heavier vehicle or you tow and haul alot, I wouldn't recommend them.
