Got E rated tires installed, 80psi max, Tire guy said it would be better to run around 65-70 psi as tires heat up. Always thought I should run max cold rating 80psi. FW weight is around 9000 lbs hooke...
If you look at tire inflation tables they say they are load limit tables not recommended pressures. If you match the table pressure to your actual load, you are running the tire at its rated limit for that pressure. These are load limit pressures, nowhere do they say they are recommended pressures.
