Goodyear at one time had a statment about over pressure by 10psi extra but not longer and it was only for their Marathon trailer tires. I can find no other brand that makes that statement.

AFIK the Marathon is the only tire with a publish bulletin to exceed the speed rating and sidewall pressure for speed.
