Tire Speed Rating Question
I'm posting this here because the speed rating of a tire seems to me to cross all lines/types of vehicles. Reading up on warranty issues/questions just now, I came across the following language ...

Applicability is the key to using inflation pressures outside of normal procedures. Just because a procedure is known doesn’t mean just anybody can apply it.
All LT tires can be aired to 10 psi above the maximum amount printed on the tire’s sidewall. Weight reduction to do so is not a factor. Speed is not a factor. So why would it be done? Maybe to cut down on tire flex with heavy loads? Anyhow, now you know it. What you ganna do with it?
Tire manufacturers do not set the pressures for your vehicle’s tires. Vehicle manufacturers do. They place the correct tire pressures on certification labels. In the owner’s manuals they tell you to never exceed the maximum amount of pressure shown on the tire’s sidewall. All of the tire warranty information I’ve read says to never exceed the maximum amount of tire pressure shown on the tire’s sidewall. So, when is this extraordinary event of increasing tire pressure going to happen? Can you get someone to take responsibility (tire manufacturer/vehicle manufacturer) for such radical increases in tire pressures?
If you take it upon yourself to jack your tire pressures up 10 psi beyond maximum sidewall inflation pressure and one of those tires blows off the side of your trailer, who do you think should pay the damages? Better to check with the tire and trailer builders before experimenting with tire pressures up above the normal recommendations.
