I run Bridgestone Dueler M/T's and Pirelli Scorpion A/T's.

The Bridgestones are superb in all conditions...I can't say anything even remotely bad about them.

The Pirellis suck. Actually, this is my second set of these. THe first set was awesome, but this set has had nothing but quality control problems...two leakers, vibration, etc. They are a superb tire in terms of traction though, probably among the best. Only thing I can tell on the quality issue is the first set was U.S. made and the ones I've been getting (two have been replaced already) are made in Brazil. Too bad.

I will buy Bridgestone Dueler A/T Revos to replace the Pirellis, as I have never had any quality or balancing problems with Bridgestones.
