Gator Attack- Never seen one before:::::

If semi drivers were responsible for damage when a tire blows, then so should anyone driving a motorhome, pulling a trailer, or driving a vehicle. What about when a cars wheel falls off and comes rolling at you on the x-way. That is why you carry insurance. Not every incident that happens can be known by inspection even before every trip. Many non-mechanical people drive, and even if it was something obvious, they wouldn't know it. If you have damage from something like this, it is covered under your insurance if you choose to carry appropriate coverages.
