I know there's charts out there by tire manufacturers that state that a tire only needs to be inflated to a point that matches it's load requirement but "hey" they get to sell you a new tire if it fails. I've yet to see any data that says a tire has been known to fail if inflated to the tire manufacturers suggested pressure stamped on the tire.
A different perspective...passenger car tires have a max pressure on them and thats what the stated load rating is based on. I have not seen any passenger vehicle where the recommended air pressure equals the max pressure. Of course, the recommended air pressure provides enough capacity to hit the vehicle's GVWR and provide good handling and ride quality. Best wear is typically at a pressure below max. In fact, if under max weight capacity but at max PSI, you are likely to see accelerated wear on the center. ST tires may be different, but I would suggest that max service life would come from inflating tires to match load weight plus some safety margin. If wear is a concern, the load pattern on the tire can be checked wi chalk or a pyrometer.
x2, that's how i look at it .
Most TT owners run out of time before mileage, not sure if it would be noticed with less miles or not.
I run my "C" 15" ST's at 45# and they are wearing fine at 6k miles.
I've been told by some owners of my model Jayco, that the OEM ST tires do show 'center wear' running them at 50# but they have more than 6k miles on them.
The reason i run a little lower pressure is because i'm running my TT below my axle and tire ratings. I often check my tire temp while on the road to make sure im doing things correctly.
P.S. i can't screw things up while on the road (in the truck's cab 10 hrs a day) because i have no 'man-cave' to hide in when things go wrong. :B
