[Fulltiming]

Clint, I don't drive quite that fast, usually 65-68, and will slow down to about 60-62 in really high temps (over 105F) and I have always run 11R24.5 H rated tires and most of the time run 305/75R24.5 Michelins on the front that are J rated. Of course I am not racing from job site to job site either. I have never seen tires do that. I do check the tire temperatures with an infrared thermometer at rest stops to insure there is nothing out of whack. The side facing the sun is always 10-20 degrees hotter than the other side. It does look like the rubber actually melted (either from heat or from chemical reaction). Certainly doesn't look like any alignment wear I have ever seen.
