Why is this aloud?

Mine does. it's kinda annoying but eh

Run flat tires were not designed for anything short of special applications and maybe some higher end sports cars. Even today with RF tires being available for cars and SUV/CUV's, they hold basically zero market share. There is nothing in law about TPMS sensors being required in the possibility of someone putting run flats on a vehicle. They became law because Ford was selling vehicles that had an already very low air pressure in all 4 wheels, and after several months would drop lower due to air naturally defusing through the tire, and that's without even considering temperature.

You can point fingers or shill for Ford as much as you want, but at the end of the day the wide adoption of TPMS in vehicles started because of Ford.

>Run flat tires were not designed for anything short of special applications and maybe some higher end sports cars

Yeah nothing says high end sports car like a Toyota Sienna or Highlander. Run flats popped up on family haulers like that in the early 2000s, it was mandated they have TPMS sensors. That was years before they mandated all cars have it due to the rollover thing.

>The reason TPMS became widespread is run-flat tires

The reason depends on the source and who has an axe to grind. Mainly, the ever increasing requirements for passenger car mileage necessitated the use of TPMS. A huge number of cars were running on under-inflated tires. That results in lowered fuel economy. When the number of passenger cars is taken into account for the whole country, that's actually a huge amount of fuel loss as well as added pollution. So TPMS was the correct approach to fight that problem.

That doesn't make any sense, who would be the one pushing for that? The manufacturers don't care what mileage the cars actually get, only the EPA rating. It's not even possible to track actual fleet mileage in a practical way.

It was part of an agreement when CAFE was re-negotiated in 2006. By putting TPMS on the table the they were able convince the EPA that they would be able to get a higher % of vehicles to stay at or near the rating, and got a smaller CAFE requirement increase because of it.

The second reason was safety, with the rise of cross-overs and SUVs vehicle weight-loading is getting much higher. A tire's strength at a given weight load is directly proportional to it's internal pressure, by creating an idiot light (and a log in the BCM), auto-makers could avoid another Firestone-Ford fiasco.
