Lynn, Jon Hansen (Hayden Industries) is a wealth of knowledge on wheels/tires, and I'm sure will comment here. It's not the speed, it's the weight. I ran a set of Jon's wheels with Kenda ribbed tires for several years on my FED, then had one go down on a 220 MPH pass. In hindsight and in talking with Jon, I probably did not have enough air pressure (I ran 32-35 psi) and had the tire come off the rim. Jon made it right with me, but I did switch back to Goodyear front runners. They are not nostalgic, but the bead is much heavier. FYI, I run 60 psi in the Goodyears.
