And as an actual Tire Design & Quality Engineer w/ 40 years experience, I base my recommendations on Science and the results of numerous invistigations on WHY tires fail, not based on a detailed reading of DOT regulations.
Too often "Regulations" are developed to make those that have to live under the regs (rv companies) happy, rather than providing the best information for the end user. Otherwise why wasn't the +10% load capacity adopted for RV applications years ago? Why are the release test requirements for ST tires the same as in 1970 where Passenger and LT tires have newer and tougher test requirements?

Yes you can follow the published regulations or you can do a better job. You can do the minimum required or you can do a better job. You can continue to have tire failures every year or so or you gan get longer tire life. Your decision, your money.
