Regardless of what the scales say, max out pressure to 65 psi. There is no down side. It will not wear the tires out faster and it will not diminish traction. Maybe on a car or truck it will but not on the marginal capacity of our st tires. BTDT for three decades.
Running at max pressure has many benefits like running cooler, less fatigue from flexing (longer life) and the highest possible capacity for the times it has to deal with pot holes and such.
How will it not effect traction? Any tire with too much air is harder than a tire with proper air. That harder tire also doesn't deflect as much under load. Having a smaller contact patch as well as a firmer tire will reduce traction, always has and pobably always will.
Too much pressure is BAD when dealing with potholes, it is not a plus. Too much pressure and a pothole is a much easier way to damage a tire than proper air and a pothole.
I have never expeiance a ST related tire failure and have always ran proper pressure not blindly ran max pressure. The only 3 flats I have had on ST tires where low speed rock punctures on some nasty roads (got a flat on my pickup 2" wide about 1 mile past where the last trailer tire went flat last fall, there was over an inch of chord sticking out). Less air would probably have been even better but I was HEAVY.
You guys that age out trailer tires before they wear out need to get out more.
