I remember asking a friend who worked at Grissom AFB with me in the early 80's, he was a civial then, but was active while B-58's were stationed there. The tires were of a harder compound or something like that, they were always getting replacement tires in. We got a lot of tires in while I was there for KC-135's and A-10's, but he said it was nothing compared to the days when the Hustler was around. Being a short tire, I would imagine that they didn't last long given the weight and speed at landings they were subjected to. The Hustler didn't operate at the same altitudes the SR and XB-70. They didn't cruise at supersonic speeds constantly like the SR does and XB was designed to do, so heat exposure wasn't as extreme or prolonged.
