Are you a car safety expert or is this your assumption how a car should behave? I doubt it is a road safety requirement for a car to learn tire diameters.

- BoorishBears 6y agoThey do learn tire diameters, they can even detect a flat using this information.
- lultimouomo 6y agoAnd to be clear, flat detection using slippage, dynamically calibrating to the actual tire diameter, is the cheapest way of doing it. Since flat detection is required by law, at least in the EU, every 10k€ new car sold in the last 5 years does it. Tesla does some marvelous stuff, but they also have some unbelievable inability to provide functionality that is nowadays just expected from a car.
- BoorishBears 6y agoIn one of my cars (124 Spider) the method used to detect tire pressure actually depends on the trim chosen for that reason I chose one that comes with performance oriented changes and interestingly enough that includes using a direct TPMS sensor in each wheel Meanwhile the base trim uses an indirect system designed around the ABS sensors
- t0mas88 6y agoIt's standard for most cars to detect the tire diameters. Not in the last place because most "sports car" brands also allow you to choose a different width rear tire. And that typically also has a slightly different diameter.
- rightbyte 6y agoYou do tire rolling radius adaption. Otherwise you can't have fancy traction control. A leaking tire will also give smaller rolling radius and that is usually how leak warnings works.
