Proper Tire Presure
What should the proper tire pressure be on ST205/75R15 tires on a travel trailer? Thanks
Forum Discussion
ST tires and car/truck tires are different, but there ARE load/inflation tables specifically for ST tires.
Stating one Should inflate to max sidewall pressure is a technique, but it is NOT the one recommended by the tire manufacturer or most trailer companies (at least every manual I have looked at says to adjust trailer tire pressure for the load). The one recommendation that should matter is the one by the tire manufacturers.
I have lots and lots of miles with ST's at proper pressure, not max, at sustained speeds up to 70-72 and have never had a neat related failure in 20 years of dragging trailers. Some trailer where at, or slightly above, load capacity and some where well under.
The OP asked for proper pressure not how to run them overinflated as most have recommended.
