Tire engineering question.
So I go and get rig weighted and inflate rear tires to 10% over psi suggested in load and inflation tables. Driving along and whats that BOOM noise? Got a blow out on the rear. In a miles long ...

If they wear okay at max pressure you will be okay, just a harder ride and maybe less traction. I don't run semi truck drives at max pressure ever. Sometimes the steers get max pressure though depending on the tire's load capacity. On the 200 ton and bigger mobile cranes we aired up and down with a CTIS, that was nice to have.
Most of my trailers have Asian tires because of the sizes. I've only lost one 225/75/R15E on the road recently. Its been years since I blew a Chinese 14" tire, I think those have improved actually.
I was blowing apart those Carlisle and Tow King 14" tires yearly for a while back in the late 90's and early 2000's. The E rated ST 15's have been doing better than the D rated for me. The Mastertrack steel belts make a difference in hot weather I think. I'm very careful with air pressure. My E rated 15" trailer tires are rated for 81 mph at 80 psi. Most ST's are only 62 to 65 mph at max pressure. Endurance ST's are rated for 87 mph I think. Good to know your truck tire specs too, I've seen cheap 12R22.5's with 62 mph speed ratings.
