The ultimate fix, as far as I'm concerned, is to move to a 4,805 lb rated Michelin XTA, Goodyear G114 or similar 215/75R17.5 tire and wheel combination. These tires are 30.7" in diameter, so fitment shouldn't be a problem.
I've run both the Michelin XTAs (on a previous Mobile Suites) and the Goodyear G114 on the current Mobile Suites and have never had a tire problem with either. No, the upgrade to 17.5" wheels and tires isn't cheap, but the peace of mind (along with the TST 507 tire monitoring system) when towing across West Texas on I-10 on a 105 degF day is worth it to me.
