I have a 2002 Tacoma TRD with 22k miles on it. It came with Goodyear AT something-or-other tires (I'm not awake enough to wander out into the blizzard and check the exact model) They've been rotated properly and often, and I keep the pressure at 32psi, checking it weekly. These tires are pretty lousy in snow, even when using 4WD. It's not a question of driving experience. I've been driving in snow for 30 years and have had little or no trouble, although my previous experience is with front wheel drive sedans and all-weather tires, usually Michelin or Toyo.
I suspect that tires like this are designed to be more bulletproof when driving on rough roads, but are a compromise when it comes to other types of driving. Is this pretty much correct?
