I'v put 3 sets of Pirelli Scorpion ATR's on 05, 06 and 07 Dodge 3500 Dually trucks. These have all been the 235/80-17 E rated tires. They have all mounted, balanced and run very quiet down the road. The problem comes with the rim protection protrusion and the chrome plastic wheel cover. It appears that as the tire flexes, it starts to rotate the hubcap, which has torn the valve stem off on two of the trucks. We've pulled the caps off and put everything back in its proper place, drive 10 miles down the road and the cap has spun and folded the valve stem over. So far the fix has been, remove the caps on one truck, change tires on the second, and the latest we changed the valve stem to a heavy duty, all metal one. Anyone else having this problem?
