Ken: Proxies are certainly certainly speed and weight rated for our trucks. I drove Proxies the first year at Bonneville, BUT only after I tested them at Standard Testing Lab of Michigan? I put 2200lb load on the tire, and got it up to 215mph and held it for 10 miles. HOWEVER, the guys misunderstood the instructions, and kept running it to failure, which was about 35miles IIRC? and all it did was chunk a small area. At Bonneville, we went over 182mph (GPS) the first year, but had a 175mph tech limit. The tires showed no damage at all.
Proxies are FAR safer than the Drag Radials or Bias Slicks for our kind of weight. How do I know? When we had a blowout on Blue in Utah, I had to put an M&H tire on Blue to get to a gas station. It didn't survive 10 miles at 50 mph.
Now where Proxies MIGHT be dangerous is lack of traction, but that's a driver issue not a tire issue.
