When a super single goes flat like that, do they diagnose it? Or is it just an automatic toss incase the sidewall/cords are damaged?
I always worry about the failue modes of SS's. With no redundant tire to take the weight, the other tandem suddenly gets way overloaded and overheated. Especially on a trailer - at which point, if the driver doesn't know a trailer tandem is flat, you're asking for a nice 120" x 18" piece of rubber to hit another car.
I always look carefully at trailer tires, especially the back axle. I know ya'll can't see it and I know most don't have TPMS. Unless you'e watching the suspension load gauge, you'd never know there's a limp axle until something flies off.
On our way to Phoenix, saw a live bottom trailer that the inner dual on the back axle/left side was completely decapped, only the sidewalls left. Driver was too busy on his phone/headset to pay any attention to me waving out the window. I was confused why a live bottom would be out in the middle of BFE New Mexico more than why the driver paid no attention to surroundings.
