Tire Manufacturer Recommendations?
Hi, We have a 2013 Skyline Mountain View Joey Select (TT), currently with 225/75R15 Power King Tow Max tires load range D's. About 2 months ago we had a blow out that caused significant damage t...

When you change to much more maximum load of tire, and you use the pressure/loadcapacity lists of ST tire maker as you give,
You then could end up with to low pressure, and so still overheating tires so tiredamage.
The ST list you give is made with the formula that was introduced in 1928 for diagonal tires.
This is what I discovered a few years ago, and wrote Goodyear about.
ST tires are calculated in maximum load for 65m/h, wich allows more deflection.
Better would be to give the ST tire the same deflection as an LT tire with same loadrange and sises would need.
And you already wrote that you now use 60% of the given maximum load. so if I would calculate it for you , compensating for the lesser deflection, it could lead to the AT-pressure given on sidewall .
This is what the tiremaker and TT maker also give nowadays, and needed to prefent damage to tires the missery that can come of it.
