You make a very valid point. Heat and sidewall flex kill tires, when on the road. Add sidewall cracking (due to age), under-inflation and excess speed and you're in for trouble. I've used Load Range E light truck tires for years on my trailer. I keep them at max inflation at all times (because they experience less sidewall flex and therefore, less heat), and change them when the sidewalls start to crack. I do exactly the same with my motorhome tires. I'll grant that it's tough to throw away tires that still have a lot of tread depth, but running cracked sidewalls is a terrible idea.
