Does anyone have any experience with the Pirelli Scorpion A/T? I currently have 30x9.5 BFG All Terrain T/A KO's with approx. 35,000 miles on them. Shortly after purchasing the tires, they began to vibrate significantly at highway speeds. It is especially bad at speeds in excess of 70 mph. I had them forced balanced which help some, but they still seem to vibrate more than they should. Recently, I came across a product test that indicates that the Scorpion A/T outperforms the BFG's both on-road and off-road. The only draw back seems to be that the Scorpion wears slightly faster. I think the test was completed by Automobile Magazine. Has anyone experienced excessive vibration with the BFG's, or have any experience with the Scorpion's.
