A surveyor's wheel, also called a clickwheel, hodometer, waywiser, trundle wheel, measuring wheel, or perambulator is a device for measuring distance.
The black molding above the wheel well is typically called a fender flare or wheel arch trim. It helps protect the wheel well and adds a stylish accent to the vehicle's exterior.
The part that holds the rim is called the "wheel hub." It connects the rim to the axle, allowing the wheel to rotate. The hub is critical for the overall structure and function of the wheel assembly.
The center of a wheel is generally called a hub.

The outside part of a wheel is called the tire. It is the rubber covering that surrounds the rim of the wheel and makes contact with the ground for traction and support. Tires come in various sizes, designs, and materials to suit different vehicles and road conditions.
When cornering, the speed of the outside wheel is typically higher than that of the inside wheel due to the different radii of their paths. If the crown wheel is rotating at 800 RPM and the inside wheel is at 500 RPM, the outside wheel's speed can be inferred. Assuming the differential allows for this difference, the outside wheel's speed would be approximately proportional to the crown wheel's speed, while the inside wheel's speed reflects the tighter turn, resulting in the outside wheel rotating faster than 800 RPM.
The circle in the wheel is called the rims

It's called a Mag wheel.
A tooth on a wheel gear is called a cog.
The steering wheel of a ship or boat is called the wheel, sometimes the trick wheel on ships with multiple steering systems. The propeller of the boat or ship is sometimes also called the wheel or screw.
A steering wheel on a sail boat is still called a steering wheel.
A water wheel with buckets is called a noria
