In my opinion, it's the Ford Pinto mentality. Until someone gets killed and/or the lawsuit costs exceed the cost savings they are enjoying by putting those rubber bands on their new trailers, nothing will change.
I'm about to pay for body work on my new 5th wheel that happened as a result of the blowout. Jayco dodges any responsibility and simply refers me to the Ranier warranty to replace the tire. I told them no thanks, I already have a good tire swing in the backyard.
