Kumho 857s, pressure?

On a trailer you don't have to worry so much about 100% max road contact nor are dealing with steerable tires or the normal vehicle NVH issues where overpressure can have a negative impact on those.

Thanks Larry! What are NVH issues?

Assuming you have upgraded tires for more reserve capacity and you have overinflated for the load, won't you start wearing out the center of the tread? As an example: Lets say I put tires on my trailer that have a stated capacity of 2094 lbs each single, 1984 dual, at 65 psi and my trailer only weighs 5,500 pounds.

Perhaps this isn't a big issue for most of us since our tires will need replacement because of age before the tread wears out?

NVH is Noise, Vibration and Harshness which comprise ride quality in vehicles. It really is not applicable to trailers since they are not normally manned when in motion. I know a lot say you should have shocks and even balance TT tires, but unless things are WAY, WAY out of whack who cares if the trailer ride as we would describe it to be ROUGH. My take is that the simple springs or rubber in torflex type axles along with the tires provide all the ride quality needed in a TT and even balancing is again IMO of questionable benefit.

Your comment about the wear while has merit at first glance is again not that important in TT tires because of the lack of the type of reserve capacity in TT tires normally vs. what one might see in passenger type tires along with the normal life expectency of TT tires being time due to deterioration and not to mileage makes this concern basically mute.

As I mentioned in my first post TT tires, especially ST tires should be run at a much higher inflation than those maybe on a passenger type vehicle, because of scrubbing during turns and even curbing and other road hazards. Finally, a loaded TT can have a much higher delta wt. wise than a typical passenger vehicle because you have to account for the varying levels of extra liquids that can approach 120 to 200 gal and that is over a 10% variance approaching 20% on a 10K GVWR trailer. Thus the tires need to be inflated to account for supporting that extra often unknown exact weight.
