Need some new tires for my trailer. I don't want to deal with blowouts. I'm of the opinion that LT truck tires are built better and more underrated compared to trailer tires. But in the 235/85R16 size I'd need, they are all rated at 3042lbs each. Load G 16" trailer tires are rated at 4080lbs each. 215/75R17.5 trailer tires are 4805lbs each. For simplicity's sake, let's assume the following: New LT tires, $600, 12k capacity New ST G tires, $500, 16k capacity New 17.5 tires, $950, 19k capacity I think the truck tires are way underrated relative to trailer tires. There's no way a decent quality load range E truck tire is more likely to fail than a $125 Chinese chunk of trailer rubber. My max load will be 3500lb trailer, 9000lb skid steer, 2500lbs of attachments. So 15k, minus 1500lbs of tongue weight, ends up around 3300lbs per tire on the trailer. So a couple of questions: How are trailer tires different from LT tires? How are the load ratings calculated for each (LT vs ST)? If LT tires are rated at 3042lbs at 106mph, what are they good for at 75mph speed index L like trailer tires?
