My partner has been asking me how tires spin (specifically on cars) and I don’t know how to answer. How do they spin without coming loose? How do they understand the speed you want them to go?
Thanks in advance!!

I’ll answer the second question cause I don’t really understand the first.
There’s a sensor that detects how fast the wheels are spinning and uses that plus the knowledge of the wheel diameter to tell you your speed. If you replace your wheels and have a smaller or larger diameter, you will need to have your speedometer recalibrated or else it will no longer be accurate. Even well worn tires will result in the speedometer being off, though not by a lot, unless your tires had a huge amount of tread and it’s all been worn away.
