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? (Just maybe because the national highway speed limit was 55 MPH back then with no relief in sight).
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. (That's sort of a misguided statement. The regulations and standards are to insure we know what the minimum safety levels are. They do not prohibit us from doing better). You can continue to have tire failures every year or so or you can get longer tire life (Than what?). Your decision, your money.

If you would take the time to read the minutes and final decision of the 2007 NHTSA tire rules committee you would know why they shelfed it. The most favorable recommendation at that meeting was 12%.
