At what psi can I travel 65-75mph?
This Maxxis pdf has the same table. Using the table(s) above, my ST175/80R13 with 1060lbs load could run at a minimum 35psi with ~4% reserve capacity. Is there a +10lbs rule? I run with +1...

I buy my tires based on this: ST tire designation: ST stands for Special Trailer tire. ST tires are designed for use on trailer axle positions only. They are not designed for the load or traction requirements of a drive or steering axle. ST tires have strengthened sidewalls to prevent the tire from rolling under the rim in turns and when cornering. All ST tires have a maximum speed rating of 65 mph. ST tires feature materials and construction designed to meet the higher load requirements and demands trailer towing presents
LT tire designation: LT stands for Light Truck tire. One definition at www.tiresafety.com defines an LT tire as any tire line or size which would typically be applied on a light truck (SUV, pickup, van). As such it could be an LT-metric tire for use on a one-ton truck or a P-metric ‘light truck’ size of a typical tire used on an SUV. Light trucks (pickups) and SUVs differ from standard passenger cars in their overall strength, load carrying capacity, center of gravity, and driveline complexity. For this reason, the tire options for light trucks and SUVs are often more complex than passenger cars. Factors such as load range, ply rating and sizes vary greatly from those of passenger car applications.
I just returned from Ruidoso NM and I traveled I-20 across Texas. I ran 75-80 MPH and I never left the right lane. I would dearly love to see some of you easterners try and drive 55-65 on I-80 across Texas. You will most likely be run over.
