When I worked in insurance, this would not have been considered the truck companies liability. A blown tire on any vehicle can have pieces fly and hit your vehicle, same as a rock that is kicked up from a tire. The claim would have been the responsibility of your own insurance minus your deductible. Sorry, but that's how it was in the entire state, not just the company I worked for and I believe most states it would be the same way. State insurance rules & regulations will specify when you can recover from another party. You could check that out to see what it says.
