The quick and short answer is: Yes it is possible but is also highly unlikely.
After reading a statement about RV fires being started by tire fires that were themselves were started by a tire failure I felt compelled to jump in with some facts.
While it is true that tires can burn and be difficult to put out once they are on fire, it is also true that it is difficult to start a tire burning.
According to Wikipedia "Tire fires are normally the result of arson or improper manipulation with open fire. Tires are not prone to self-ignition, as a tire must be heated to at least 400° Celsius (750° Fahrenheit) for a period of several minutes prior to ignition.
Now I can almost hear some saying: "Ya but what about a tire blowout?" Well lets consider a tire failure. You are driving down the road at 50 MPH or more and there is a sudden, loud "BANG". You are startled but with luck and skill, you can pull off the road to look at the damage. Most likely you find a tire in multiple pieces along with some damage to your RV. What you do not see are pieces of burning rubber strewn along the road. If we consider the process of a tire coming apart it may be easier to understand why we don't see burning rubber when we stop because of a tire failure.
Considering the two major reasons for a tire to fail. 1. The belt separation where the belt and tread detach or become separate from the body of the tire. and 2. The sidewall fails because of excessive flexing while being driven at extreme low inflation (usually with an 75% or greater air loss).
If we look closely at the sidewall flex failure of a regular Passenger, LT or Trailer tire we will see that the body cord is usually Polyester surrounded by various rubber compounds. The process of over flexing or over bending while running at highway speeds the same time can result in the polyester overheating. This can result in the Polyester actually melting as seen in this picture of fused Poly cords.
If you stopped right away they tire might look like this where we can see the "Melt line" running 360° around the tire sidewall.
Think for a moment what you do when you cut a piece of Nylon or Polyester rope. You get out a lighter or match and fuse the end.
Polyester looses half it's strength at 300 to 350°F and melts at about 480°F. This is a far cry from the 750°F ignition point of tire rubber.
The second mode of tire failure, Belt separation
takes many hundreds or even thousands of miles to result in a tire coming apart and if the tire has a Nylon cap ply and you occasionally may see signs of some of the Nylon melting at 430°F we see that the rubber that is holding the belts together fails by "de-vulcanizing" or reverting to it's uncured state and looses almost all of its strength . This occurs at about 348°F.
Having covered the examples of why it is unlikely that a tire failure can start a fire, the question remains: Is it impossible? The answer to that is Yes it is possible to start a tire on fire but this usually occurs when the fire started with a brake or bearing failure that ignites the axle grease, or even the brake fluid which both have an ignition temperatures of about 550°F.
Someone is probably thinking about their steel body radial on their big Class-A RV. Yes they do not have Polyester or Nylon that can melt but the rubber in those tires can still revert and lose all it's strength and still be 200°F under the ignition temperature.
A final observation: We need to remember that tires are being run 24/7 at tire plants around the world with most being "run to failure" yet we simply do not see tire test labs suffering tire fires initiated by the failed tires.
I hope you understand why I would say "Please do not spread the false narrative that tire failures start tire fires. The facts just do not support that claim.
