I just replaced the factory BF Goodrich All-Terrain T/A KO tires on my Tacoma Prerunner(+TRD). At only 32K they were terrible. Very poor dry-traction and wet was even worse. Total crap.
Ordered a set of Bridgestone Dueler A/T Revo's and I'm very impressed so far. Very quite on the road and a night & day difference as to traction and control. They get really good reviews.
Tire Rack had a great price and service. And even with the added exspense of shipping and mounting locally there was no way any local retailer could come near the total price.
