We just learned about the Rims.
Another part of a car is the Lug Nut or wheel nut.
The lug nuts are what hold the rims onto the car.
If you need to replace a tire or work on the car brakes or the axle, you start by lifting up your car with something called a jack, and then removing the lug nuts using a tool called a lug nut.
