Factory-P and all,
Tire pressure when you inflate the tire....
If you go on a racing circuit you will notice that race tire manufacturers do inflate the tire in a cage.
Want a story? 15 years ago in the ALMS paddock, a Michelin service engineer, whom I knew from the late 80s in Formula 3, nearly lost his life.
The tire did not exploded under the inflating pressure; the rim imploded! Rim manufacturing problem, lack of homogeneity in the casting of one of the spoke. Should have been seen in quality control but wasn't.
A piece of rim clipped a piece of his ear. Another rim part went through the truck awning and was found in the paddock 400 meters from the truck. The guy could not hear for 2 weeks.
If he would have had his head 50 mm away from where it was he would have been killed. Since that time Michelin and then others race tire manufacturers only inflate the tire in a steel cage.
The Michelin race engineer is well and still working these days; I saw him at Le Mans 24 hours this year. But that day the gods where with him. Racing can be dangerous and not only on the circuit.
