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!!

Tires don’t become loose because the pressure between the sidewall of the tire and the rim is literally an air tight fit. Then throw in internal pressure pushing on that bead and you e got a nice snug fit (although in instances of extreme power the friction between the ground and that bead on the rim becomes too great and the rim will spin leaving the tire behind.)
The tires know how fast to go because there are gears inside the transmission that take power from the engine and by changing ratios attain higher and higher speed. There are sensors in the transmission and each wheel that make sure everything is working as designed so you know how fast you’re going at any given time.
