5 Main Functions of Tires and Wheels
Below are the main functions of car tires and wheels. Take a look.
1. Propels Your Car Without Skidding
Tires and wheels are mainly made to direct the car forward. Sometimes the weather may be wet or dry. With that in mind, a car tire usually tackles various temperatures and helps to push your vehicle in the required direction.
Your car will move without skidding because of the good tread depth grip in tires.
2. Bears the Load of the Vehicle
A tire is usually made of rubber to help hold air. As the air is filled in the tire and wheels, it keeps the vehicle’s weight easily. As you drive, the load on the car is mostly directed to the roll center when your vehicle is accelerating, moving forward, braking, and turning.
The ability of the tires to withstand the weight usually depends on the air pressure immersed in them, making air the most vital ingredient for safety and performance. Any wheel and tire with the right pressure usually give great handling and traction.
That’s why you should always maintain the required air pressure in all your car tires and wheels for great benefits while driving. You can use nitrogen inflation rather than normal air for your tires.
3. Gives Cushioning to the car Against Any Road Shock
Some roads usually have cracks, potholes, and bumps, leading to a bumpy ride. However, your tires which are in great condition will give you a smoother ride even on these rough patches. The tires and wheels will withstand the impacts and assist in absorbing and damping any shocks.
4. Helps the Vehicle to Change Direction and Switch Without Slipping
The tires and wheels in your car help you change direction as you control the steering wheel. In turn, you get to drive in the order you want. They also help your vehicle to stand stable as you navigate through corners.
With tread depth, tire quality, air pressure, and tread pattern, your vehicle will remain steady even if it turns.
5. Sends Acceleration, Cornering Forces, and Braking to the Ground
Every vehicle is usually judged by its handling, braking, and acceleration effectiveness. However, the wheels and tires are the ones behind the great performance of a car. They create and send physical forces like braking, acceleration, and cornering to the entire road surface.
The friction that is generated between the road and the tires is the one that spearheads the transmission of forces to the ground.
On top of these main functions, tires and wheels also increase fuel efficiency, give grip even on dry and wet roads, enhance handling stability, and give you a comfortable ride. They are vital parts of the vehicle since they guarantee safety.

7 Different Parts of Car Tires and Wheels
Here are the different parts of car tires and wheels:
1. Wheel Rims
They are a link between the tire and the hub. In simple words, you install the tire on the rim. Then you bolt it to the hub. You will find many rims made from stamped steel. Then stamped and welded to form an edge.
On the center part of the rims, you will see wheel mounting holes. The flange secures the tires in a good place when you have installed the wheels.
Wheels are usually cheap to manufacture, and they are long-lasting. Some are chrome plated for an elegant appearance, while the remaining ones are painted to be used with wheel covers.
Current vehicles use rims generated from materials compared to steel, known as customs. The use for custom wheels includes graphite, aluminum-magnesium alloys, and plastic composites. Then they are designed, colored, and styled the way you prefer.
2. Wheel Bearings
This part of a car wheel generates a low-friction link between the stationary and rotating vehicles. You need to understand that all-wheel bearings come as antifriction bearings. These bearings contain three basic parts: rolling element, inner race, and outer race.
The remaining parts include bearing cages that distinguish the specific rolling elements as they bend and the shield or seal that secures the lubricant inside while water and dirt come out. Always ensure you choose the right wheel bearing to withstand any load and maximum bearing speed.
It would be best to determine the entire bearing side and the rolling elements for great performance without having to replace any.
3. The Hub
The hub is located in the middle section of the wheel. It is where you attach the wheel. It also accommodates the rotors, calipers, and brake pads, allowing the vehicle to move and stop. Five bolts from the hub center are bolted together with the lug nut.
Additionally, the hub keeps the wheel firmly attached to the vehicle.
4. Brake Rotors
In a car, a rotor refers to a component of the disc brake system that rotates with the wheel and is clamped down on by the brake caliper to slow down or stop the vehicle. It is typically a circular, flat disc made of cast iron or other durable materials and is mounted directly to the wheel hub.
During braking, the brake caliper squeezes the brake pads onto both sides of the rotor, creating friction that slows down or stops the car. The rotor’s function is to provide a smooth, even surface for the brake pads to grip, dissipate heat generated by the braking process, and withstand the forces of friction and heat.
Rotors come in different sizes and designs, depending on the make and model of the car and the intended use of the vehicle. Some rotors may have ventilation holes or slots to improve heat dissipation and reduce brake fade, while others may have a cross-drilled or slotted pattern to increase the rotor’s surface area and improve braking performance.
Over time, rotors can wear down or become damaged, which can affect the performance of the braking system and lead to safety issues. Worn or damaged rotors can cause uneven wear on the brake pads, increase stopping distances, and cause the car to vibrate or shake during braking. Regular maintenance and inspection of the braking system are essential to ensure safe and reliable operation of the vehicle.
5. Brake Calipers
In a car, a caliper refers to a component of the disc brake system that applies pressure to the brake rotor to slow down or stop the vehicle. The caliper is typically located near the wheel and is attached to the steering knuckle or strut of the suspension system.
The caliper contains one or more pistons that are connected to brake pads. When the driver steps on the brake pedal, hydraulic pressure is generated in the brake lines, which causes the piston(s) in the caliper to move outwards and push the brake pads against the rotor. This creates friction between the brake pads and the rotor, which slows down or stops the car.
There are two main types of calipers used in cars: floating calipers and fixed calipers. Floating calipers are the most common and are designed to move in and out on pins or bolts to apply pressure to both sides of the rotor. Fixed calipers, on the other hand, remain stationary and apply pressure to the rotor from both sides.
Calipers are critical components of the braking system and play a crucial role in ensuring the safety and reliability of a car. Over time, they can wear down or become damaged, which can affect their performance and lead to issues such as decreased braking efficiency, uneven brake pad wear, and brake noise. It is important to have the brake system inspected regularly and to replace any worn or damaged components to ensure safe and effective operation of the vehicle.
6. Brake pads
In a car, brake pads refer to the replaceable components of the disc brake system that apply pressure to the brake rotor to slow down or stop the vehicle. They are typically made of a composite material, such as ceramic or metallic fibers, bound together with a resin.
When the driver presses the brake pedal, hydraulic pressure is generated in the brake lines, causing the brake caliper to push the brake pads against the brake rotor. This creates friction between the brake pads and the rotor, which slows down or stops the car.
Brake pads come in different sizes and designs, depending on the make and model of the car and the intended use of the vehicle. Some brake pads may be designed to provide high performance and durability for racing or heavy-duty use, while others may be designed for quiet operation and longer life for everyday driving.
Over time, brake pads can wear down and become thin, which can affect their ability to create sufficient friction to slow down or stop the car. As a result, it is important to have the brake system inspected regularly and replace the brake pads as necessary to ensure safe and reliable operation of the vehicle.
In summary, brake pads are an essential component of the disc brake system in a car, responsible for creating friction between the brake rotor and the caliper to slow down or stop the vehicle. They are replaceable and come in different sizes and designs depending on the intended use of the vehicle.
One of the crucial factors during the wheel and tire design is how the rim will be mounted to the axle flange or hub. In almost all trucks and cars, you will find wheel studs in the axle flange or hub.
All the wheel studs are threaded studs or bolts fitted into the flange. A wheel flange usually acts as a link to connect your car’s wheels to the axle.
Flanges are located on the sides of the wheels to prevent the tires from accidentally slipping. A flange also helps the tire remain connected to your wheel regardless of weather conditions.
8. Lug Hole
Specifically, located on the center disc, a lug mainly reassembles the bolt circle. Because of the lug hole, the lug nuts are usually fastened. You will also see the bolt circle diameter, a circle size secured by the lug holes.
The barrel typically is the area of the vehicle wheel that falls between the inboard rim edge and the outboard face. Its main function is to give a surface whereby you will fit the tire. The barrel’s inner diameter is the drop center. It influences the mount wheel type greatly.
Also, flanges created by the barrel’s sidewalls usually stop the tires from slipping your car as you are driving.
10. Wheel Fasteners
Every wheel and tire have to be fastened to the axle flange or the hub using fasteners. It usually depends on the design of the tire and wheel. The wheel studs or bolts are typically mounted as wheel fasteners in your axle flange or hub.
To limit the studs from entirely piercing the hole in the flange, the stud’s head is normally wider than the hole. Then the middle part of the flange is raised a little bit and mounted on the center of your rim to help center the wheel.
3 Types of Car Wheels
Manufacturers usually design car wheels using three materials: steel, alloy, or carbon fiber. The one you prefer will depend on the priorities of your vehicle. Let’s have a look at each of the types.
1. Steel Wheels
Steel is the most used wheel type in a car. They are mostly preferred because they are basic and get the job done quickly. Steel wheels are quite durable and tough hence perform in all seasons. Additionally, steel car wheels are cheaper, making you save money.
The only disadvantage of steel is that it does not make your vehicle stand out. You will also spend more cost on other car parts. Otherwise, steel car wheels have everything else you require in a car wheel.
If you are looking for something good in terms of quality, there are better options than steel. It is pretty heavy, and causes drag.
2. Carbon Fiber Wheels
This type of wheel is light, so it is good in acceleration. Carbon fiber wheels are stronger than alloys and can withstand even more extreme conditions. They have a combination of steel and alloy traits but not their weaknesses.
Although they are quite expensive, they will serve you better, and you will enjoy a comfortable ride. Their only downside is that they are more costly than alloy and steel wheels. Also, if they get damaged, you can’t repair them. You will have to buy another one and replace it.
3. Alloy Wheels
First, an alloy is a combination of metals. In the case of car wheels, it is a combination of aluminum and magnesium or nickel and aluminum. Aluminum metal is common in these wheels because it’s the primary metal.
Alloys shine in the weaknesses of steel. They are lighter as compared to steel. They also do not slow -down in case of acceleration.
Alloys have also been tested to offer a more comfortable driving experience. They are mostly preferred by car owners or drivers for collectible cars over regular daily vehicles. These light car wheels give your car an agile driving experience, making them a preferred choice for cars driven specifically for special events.
The problem with alloy car wheels is that they are not durable. They mostly wear and tear during winter than steel. Some even crack because of pressure during winter. They are also expensive, but you will save more fuel because of their lighter wheels.
3 Types of Car Tires
Just like wheels, also car tires usually come in different types. They are specifically designed for various seasons. Every time you shop for new tires, consider the climate you are around. Here are the different types of tires you will notice in cars.
1. Summer Tires
These types are specifically manufactured for hot weather. Simmer tires withstand hot and dry temperatures. In addition, they can withstand summer humidity and rain. Summer tires are ideal for those who reside where winter doesn’t reach freezing temperatures.
However, summer tires may not be ideal for people who live in areas that get cold winters. These tires don’t bear slippery roads, snow, or other winter conditions.
2. All-Season Tires
All-season car tires can withstand both summer and winter or a combination. You can use them in both dry and wet weather. They have great traction and grip, but you cannot use them in extreme winters.
They can withstand small snowy conditions, but they should be light and disappear fast.
3. Winter Tires
Winter tires are also known as snow tires. You use them in winter since they are softer and do not become rigid when the temperature decreases.
Additionally, these tires have deeper grooves; hence, they have a great grip while on slippery roads. Areas that experience long winters usually make people have winter tires and summer tires so that they can switch each time without inconveniencing themselves.
