tire air pressure
I have had some tire problems in the past so I know a lot of the do's and don'ts. So I have this question which I probably know the answer but I will throw it out here anyway. The last 2 years we have...

So FE as I have posted before. Two trailers of similar size and weight. Mine a 29 ft Cardinal buddies was a 29 ft Montana. Both with 5200 axles and OEM LT235/85R16E's. Mine stated 65 pounds inflation and his 80 pounds. 65 pounds happens to match industry standard inflation charts for the weight on the axles.
So I have a lot less faith in what trailer manufacturers put on placards than you do. My placard would indicate his tires were over inflated and his placard would indicate mine were under inflated.
Somewhere people have to learn to think for themselves or go to a good commercial tire shop and talk to techs the deal with customers that make a living day in and day out with their rigs.
In repeated calls to Michelin's CS I was advised to follow the inflation charts if I knew my weights. They stated that over inflation reduced contact patch/braking and increased chances of impact damage.
After many years of service from my RIBs I settled in at 71 lbs inflation based on wear patterns. Tires were in service for 6.5 years and 40K+ miles. I run the new(2 years old now) R250's at the same 71 pounds.
Of course I choose to spend the money for the best tires available for a trailer my size and do not have to worry about ripping the cap off the carcass as jimnlin noted above.
I have long thought the ST tread pattern, tight cornering and light construction was part of their downfall.
