I don't see any manipulation above the sidewall specs.
The tire's max is 50psi, the tables say 35lbs per the actual weighed load, and adding 10lbs gets me to the 75mph figure while staying under that 50psi max.
I called K-Z and was told to run the tires at the max, or 50psi.
I do drive 60-65mph, but I don't like the worry if I exceed 65mph on occasion.
I have found that
Kumho 857 has a higher speed rating.
