Functions of Car Wheel:
Over the years, cars have taken on a variety of bodies, designs, and sizes. Some auto parts are now obsolete and have expired or been replaced with new versions. The car parts that have always been in use are the wheels.
These circular structures generate rotary motion and are responsible for moving the car from one point to another. Therefore, wheels are an essential part of any automobile. Since their invention in 3500 BC, these circular blocks have taken on various designs, structures, and styles.
Despite this, his work remains the same. The wheel consists of several parts that play different roles to ensure that it functions as expected. Some of these parts have been the subject of misunderstanding and confusion.
Below, we break down these parts and understand their structure, functions, and adaptations. And so, if you are a car person, knowing the wheel parts and their functions is essential.

Parts of Car Wheel:
#1. Wheel Bearings
Wheel bearings create a low-friction connection between the rotating wheels and the stationary vehicle. All-wheel bearings are antifriction bearings. Antifriction bearings consist of three basic parts: inner race, rolling element, and outer race.
Other parts of antifriction bearings include bearing cages, which separate the individual rolling elements as they bend, and the seal or shield, which keeps lubricant inside and dirt and water out. Wheel bearing must be carefully selected to deal with the type of load, maximum bearing speed, where the bearing will be used on the vehicle, and what the vehicle is used for.
The total bearing size, as well as the size of the rolling elements, should be determined to give the longest service life without unnecessary weight & size.

#2. Wheel Rims
The Wheel rims are the connection between the hub & the tire. The tire is installed on the rim, & the rim is bolted to the hub. In many cases, rims are made of stamped steel. The Rim part is stamped to shape and then welded to the final form.
In the middle part, there are wheel mounting holes. On some wheels, additional stamping is used to attach the wheel cover; The flange holds the tire in place once installed and inflated. Steel rims are relatively lightweight and reduce the amount of unsprung weight.
They are also durable and cheap to manufacture. Some steel rims are chrome plated for appearance, while others are painted and used with wheel covers. Modern vehicles are increasingly using rims made from materials other than steel.
These rims are commonly called custom rims. Common materials for custom rims are aluminum, aluminum-magnesium alloys, and graphite and plastic composites. The rims are made of strong metal such as steel to withstand the force and load of the car. The width & diameter of the rim determines the size of a car tire. You can get customized rims as aftermarket car spare parts.
These customized rims are colored and styled to your liking, but they come with additional costs. The barrels of the rim create surfaces for a tire to be mounted on. The inner diameter of the barrel is the drop center, which determines the mount wheel type.
For front-mounted wheels, the drop center is near the front face of the wheel. Rear-mount wheels, on the other hand, have drop centers near the rear of the wheel.

Tires do two things:- they reduce shock and provide traction. In their role as cushioning devices, they can be considered part of the suspension system. As for traction devices, they transmit engine power, as well as braking and turning efforts, to the road. Tires cover and prevent wheel rims from rubbing or touching the ground.
It also acts as a cushion & shock absorber when you drive on rough terrains. The main parts of the tire are the thread and its body. The tread or track is the outermost rubberized part of the tire. It is in direct contact with the ground and wears out over time.
The tread consists of grooves and notches, which are called tread patterns. This pattern has two important roles – to increase the friction between the ground surface and the tire and to direct water and debris away from the wheel.
On the other hand, the body acts as a habitat for a specified amount of compressed air. Tires come in different sizes to fit different cars. You can stamp your car’s tire size and other specifications on its sidewalls. You can also find it engraved or printed on the glovebox door, your door jamb driver’s side, or within the fuel tank hatch.
Specifications found on the sidewalls of tires include the following:
- Tire width
- Tire height and width ratio
- wheel diameter
- Treadwear, traction, and temperature grade
- Tire Ply Composition and Materials Used
- load index and speed symbol
- Inflation and load limits

#4. The Hub
The hub is the middle part of the wheel to which the rim is attached. It is home to brake pads, calipers, and rotors. All this attaches to the axle & allows the vehicle to move & stop. The tires are attached to the hub, and from its center, five bolts are mounted together with the lug nut.
The hub is home to the mechanics of the wheel and keeps it attached to the vehicle. When it’s time for new rims and tires, meet us at your local RNR Tire Express. We have everything you need to makes your car or truck look road-ready.

#5. Wheel Fasteners
An important factor in the wheel and tire design is the way the rim is mounted to the hub or axle flange. On almost all cars and trucks, there are wheel studs in the hub or axle flange. Most wheel studs are threaded bolts or studs that are pressed into a hub or flange.
A sharp area on the back of the stud is cut into the hub or axle metal to keep the stud loose. The head of the stud resembles a bolt head and is wider than the hole in the hub or flange. The head prevents the stud from coming completely through the hole.
To properly center the wheel, a middle section of the hub or flange is raised slightly and holds the center of the rim in position. To install the wheel, holes are drilled into the middle of the rim over the studs, and lug nuts are threaded through on the stud.
The lug nuts can then be tightened in a cross or star pattern. The tapered end of each lug nut corresponds to a tapered area in the wheel mounting hole. Matching tempers help center the wheel. On most steel wheels, lug nuts can be tightened by hand or with an impact wrench.
Custom wheels have different metal expansion rates than steel and iron hubs, and the lug nuts must be tightened to a specific torque.

#6. Valve System
Car tires inflate or deflate through their valve system. The wheels of the car have a valve mechanism that is integrated with the tire pressure monitoring system to help the driver know the pressure status at all times. For more information about tire pressure sensors, tire maintenance, and other matters relating to your car, please visit Carport Australia.

Parts of a Car Wheel and Axle
In general terms, an axle is a shaft between the wheels, which can be fixed, or rotated in unison with the wheels. Historically, the main examples of the wheel and axle setup were winch, mill, and even a doorknob.
What Are the Parts of a Wheel
Before we get into the types of wheels, you should familiarize yourself with the various components of the wheel, which include three main parts: the tire, the rim, and the hub. The tire, which is the width of the wheel, goes around the rim and gives the wheel grip on the road surface.
