Choosing the correct tyres for safety and p erformance for your vehicle is a crucial yet often overlooked decision that significantly impacts safety, performance, and overall driving comfort. For those looking to enhance their daily driver, the temptation to upgrade to larger, high-performance tyres is strong. But is this the right choice for your vehicle?

Tyres for Safety and Aesthetics

Most vehicle owners aim for the best tyres, whether opting for premium tyres or a more affordable alternative. While aesthetics play a role, tyres must primarily serve their purpose of providing safety and performance. But with so many options, the main question is whether to choose a premium tyre that aligns with the vehicle’s specifications or look for a more affordable option. Premium tyres are engineered with advanced materials and manufacturing techniques to deliver exceptional all-around performance. These tyres undergo rigorous research and development, with attention to factors like safety regulations, customer expectations, and evolving vehicle technologies.

The Role of Premium Tyres

Premium tyres often feature advanced rubber compounds designed to improve grip. For high-performance tyres, the sidewall construction is reinforced for greater rigidity, which improves handling precision in both wet and dry conditions. In contrast, premium tyres for less performance-oriented vehicles, such as an entry-level Volkswagen Polo, tend to have softer sidewalls for a more comfortable ride. However, all premium tyres, regardless of the target vehicle, meet strict safety and quality standards, ensuring they are both safe and reliable.

Ryan Visagie, Product Communications Manager at Continental Tyre SA, emphasises that premium tyres are characterised by high-quality materials, advanced production processes, and extensive R&D. Each tyre, regardless of its intended use, adheres to stringent safety and performance standards.

Budget Tyres vs. Premium Tyres Options

Although budget tyres are available in the same sizes, their manufacturing processes don’t always meet the high standards of premium tyres. Budget tyres may fall short in performance and safety, as their production lacks the precision and advanced materials found in premium alternatives. Here are some examples of budget and premium tyre options available in South Africa:

Budget Tyre Options:

Hankook Kinergy Eco – Known for providing a comfortable ride at an affordable price, this budget option is often chosen for compact cars.
Westlake SA07 – A more affordable option, offering decent performance for everyday driving.
Toyo A24 – A budget tyre suitable for regular city driving, with a focus on durability and economy.
GT Radial Champiro – Provides good value for money, offering reliable performance in dry conditions at a lower price point.

Premium Tyre Options:

Continental SportContact 6 – A high-performance tyre offering excellent grip and handling, even in wet conditions.
Michelin Pilot Sport 4 – Known for its superior handling and high levels of safety, this tyre is perfect for performance vehicles.
Pirelli P-Zero – A premium choice offering exceptional performance in both wet and dry conditions, commonly found in high-performance cars.
Bridgestone Potenza RE-71R – A top-tier tyre designed for sports cars, providing precision handling and high-speed performance.

While budget tyres may seem like a cost-effective choice, premium tyres are designed to offer superior performance, safety, and longevity. The investment in premium tyres can ultimately lead to a better driving experience and greater peace of mind.

Risks of ‘Over-Tyring’ Your Vehicle

Some car owners may attempt to fit high-performance tyres to vehicles not designed for them. While this might seem like a way to enhance grip or handling, it can cause significant issues. High-performance tyres typically have a wider profile and shorter sidewalls than standard tyres. Increasing tyre size can disrupt the vehicle’s handling, negatively affect fuel efficiency, and distort the accuracy of the speedometer. Larger tyres may even rub against the wheel arches or suspension components, causing wear and damage.

Moreover, the relationship between the tyres and the suspension system is crucial. A mismatch can lead to poor handling and a less predictable driving experience. The extra strain on the suspension can also accelerate wear on the springs and dampers.

High-performance tyres operate best within a specific temperature range. If fitted to a car that can’t generate the necessary heat, these tyres may fail to provide optimal performance, reducing safety and grip. Additionally, these tyres generally wear faster due to their softer compounds and often come with a higher price tag.

Should You ‘Over-Tyre’?

Although the idea of upgrading to larger, high-performance tyres may seem appealing, it might not be the best choice for every vehicle. For example, a Volkswagen Polo GTI comes with 215/45 R17 Continental SportContact tyres as standard, with an optional 215/40 R18 size. Opting for a significantly larger tyre may impact fuel efficiency and offer little improvement in performance, making it an impractical investment.

Conclusion

In the end, sticking to the manufacturer’s recommended tyre specifications is usually the best option. Premium tyres, however, offer an investment in safety, control, and confidence on the road, and are a worthy consideration when looking to enhance your vehicle’s performance and safety. While upgrading to a larger tyre might seem like a simple way to boost your car’s capabilities, it’s essential to consider the potential downsides before making the change.
