Doug: Not sure why the sidewalls gave up at just over 100 passes , we rotate properly and i never let get into hard paddling more than once no matter where we go. Knowing the car so well, I pretty well know where to put tire for first pass after looking at track . Thats why i was so shocked when the tire started going away so quickly once we put the new bullet in. We normally run a 29. x 10.5Ws at 12.5 to 12.75 lbs on a 3200 lbs car. Perhaps it was just time rather than passes on the tire??
At any rate, we are loving the radials.
Thanks for info on Crew Chief.
