What Constitutes a Passenger Car Tyre?
Rubber
Natural and synthetic rubber (also known as polymer) are the main components of a car tyre. Depending on the variety, these materials provide a high level of slip resistance and, after processing, the preferred elasticity. Apart from that, rubber has the disadvantage that it wears out quickly and can harden at low temperatures or become soft at high temperatures.
Fillers
In general, fillers are added to the rubber. These fillers can be carbon black, silica, carbon or chalk. They bind the rubber and make it more resistant to wear, as rubber on its own can crumble, particularly as a result of breaking. We use fillers to counter this effect and increase the mileage of your tyres. However, this can harden the rubber compound a little.
Fillers are also the reason for the colour of tyres. Carbon black was the first filler to be used and gave the tyres their colour. However, coloured tyres never made their breakthrough, even when other fillers and therefore other colours came into play later on. That is why tyres are still black to this day.
Plasticiser
Plasticisers are needed to ensure that the tyre gives you a positive and safe feeling while driving, even in snow and rain. These oils and resins make the tyre flexible and improve the grip of the material. For you, the driver, this means that plasticisers improve rolling resistance. Oils also add to the slip resistance of the tyre. That's why more oils are used in winter tyres than in summer tyres; plasticisers prevent the rubber from hardening at low temperatures.
Factors to Consider When Changing Passenger Car Tyre Sizes
Several factors should be considered when changing tires to ensure the best performance, safety, and compatibility with your vehicle.
Tire Width
For better grip and control, wider tires are usually a good choice. However, excessively wide tires tend to have a higher rolling resistance, which can lower your vehicle's fuel economy. While the wider contact patch offers improved cornering abilities, these tires can sometimes feel heavy or clumsy.
Wide tires typically work best with vehicles with high horsepower and torque, as they can significantly enhance acceleration, reduce wheelspin, and improve grip.
If you opt for narrow tires, you might enjoy better mileage and lower fuel consumption due to reduced rolling resistance. The narrow tread pattern also makes them a suitable choice in extreme winter, as they can cut through the snow and ice more effectively.
However, this also means limited traction and handling and reduced stability, particularly at higher speeds.
Tire Height
Taller tires can give your vehicle more ground clearance, deliver a smooth ride, and change overall handling. These tires are more popular among 4WD vehicles.
While bigger tires do offer several advantages, it is recommended that you follow your vehicle manufacturer's guidelines for the most appropriate tire sizing.
Width & Aspect Ratio
A key component of tire sizing is the width and aspect ratio, which influences the tire's overall profile and performance characteristics.
To find the correct aspect ratio, consider the vehicle's specifications and load requirements.
Tires with a lower aspect ratio (40, 45, 50) have a shorter sidewall height, giving the car a sporty look. Additionally, this ratio enhances handling and stability, particularly when driving at higher speeds. It's important to note that opting for lower aspect ratio tires may compromise ride comfort.
Conversely, tires with a higher aspect ratio (70, 75, 80) have a taller sidewall. This delivers a more comfortable and cushioned ride with better impact absorption. However, it's worth noting that tires with higher aspect ratios typically offer comparatively less responsive handling.
Important Functions of a Passenger Car Tyre
Carry the weight of the vehicle
A tyre is like a rubber casing that holds air. The air that is filled in the tyre is responsible for carrying the weight of the vehicle. A vehicle's weight moves around the roll center when the vehicle is braking, accelerating, turning or moving forward. For e.g., when brakes are applied as hard as possible, the front suspension gets compressed and a lot of the vehicle's weight is shifted to the front tyres. Similarly, when you accelerate the weight is shifted to the rear tyres. The weight bearing ability of the tyres depends on the air pressure that is filled in it. Therefore, air is the most important ingredient when it comes to safety and handling performance. A tyre filled with the right air pressure provides good traction and handling. Hence always maintain optimum air pressure in all four tyres and for added benefits you could also go for nitrogen inflation instead of normal air for your tyres.
Propel the vehicle without skidding
The tyre is designed to move the vehicle forward. The mechanics of the tyre on a wet surface is different than the mechanics on a dry surface. The tyre tackles different temperatures and road conditions to push the vehicle in the desired direction. Good quality tyres that have the recommended tread depth grip the road better and help the vehicle move without skidding.
Provide cushioning to the vehicle against road shock
Road imperfections such as potholes, bumps, cracks etc. contribute to a bumpy ride. Tyres that are in a perfect condition provide a smoother driving experience on rough patches. As the vehicle moves through the irregular surfaces of the road, various systems such as the suspension, shock absorbers, the wheel etc. get affected. But it is the tyre that absorbs the impact first. While dealing with the various forces that act on the vehicle, the tyres also help in absorbing and damping the shocks.
Enables vehicle to change direction and turn without slipping
The wheels of your vehicle change direction as you steer the steering wheel. This enables your vehicle to move in the direction that you want. It is the tyres that help your vehicle remain stable as the vehicle changes its trajectory. Along with tyre quality, tread depth, tread pattern, the air pressure in the tyres plays an important role in maintaining vehicle stability while turning.
Transmit acceleration, braking and cornering forces to the ground
While a car's performance is very often judged on how effective its acceleration, braking, handling and cornering is, the fact is, it is the tyre that is responsible for accomplishing the desired performance from the vehicle.The tyre generates and transmits the physical forces such as acceleration, braking and cornering to the road surface. The friction between the tyres and the road is what makes it possible to transmit these forces to the ground.
