Comment on Do you need to adjust your speedometer if you change the size of your tires?
frank@sopuli.xyz 2 weeks agoWell there’s lots of ways to measure speed. Some use a worm gear in the transmission, some use a sensor on the wheel hub. But all of them take tire diameter into account, unless you count like GPS, which afaik (though probably some really shitty privacy invading car may prove me wrong) isn’t a thing for speedometers and odometers
So yes, all production cars, I believe.

Pretty sure you can’t use GPS by itself since it can be inaccurate or not work at all inside tunnels.

I knew a guy with a busted speedometer that used a GPS and yes you’re correct. Anytime he was in a major city it was problematic.
