Braking performance is one of the most critical aspects of vehicle safety. A car’s ability to stop quickly and efficiently depends on several factors, but tyre choice plays a particularly significant role. Different tyre sizes, tread patterns, and rubber compounds can either improve or compromise braking performance, especially on wet or icy roads.
In this article, we analyse statistical comparisons of various tyre types, including tyres 215/35/16, and their impact on braking distance in different driving conditions.
The Impact of Tyre Type on Braking Distance
Studies show that high-performance tyres with optimized tread patterns can reduce braking distances by up to 15% compared to standard all-season options. The difference is even more pronounced in extreme weather conditions, where summer, winter, and all-season tyres perform differently.
Braking Distance by Tyre Type (Dry Surface)
- High-performance summer tyres – Shortest braking distance due to superior grip and rigid tread compounds.
- All-season tyres – Moderate performance, offering a balance of grip and durability.
- Budget tyres – Often have longer stopping distances due to less effective rubber compounds and tread designs.
On dry roads, high-performance tyres with a soft rubber compound and a wider contact patch provide better stopping power. However, they may wear out faster than standard options.
The Effect of Wet and Icy Conditions
When roads are wet or icy, tyre choice becomes even more crucial. Tread depth, siping (tiny slits in the tread), and rubber flexibility at low temperatures significantly influence stopping distances.
Braking Distance Increase in Adverse Conditions (Compared to Dry Roads)
- Wet roads: +30–40% increase in braking distance.
- Snow-covered roads: +50–100% increase in braking distance.
- Icy roads: Up to ten times longer braking distances.
Winter tyres, designed with softer rubber and deeper grooves, help maintain traction in cold conditions. In contrast, summer tyres harden in low temperatures, reducing grip and extending stopping distances.
The Role of Tyre Size and Pressure
Tyre dimensions also play a part in braking efficiency. Narrower tyres can cut through water more effectively, reducing the risk of hydroplaning, while wider tyres provide better dry-road grip. For example, tyres 215/35/16 are often used in performance vehicles to enhance stability and control.
Correct tyre pressure is equally important. Under-inflated tyres increase stopping distances due to reduced road contact, while over-inflated tyres decrease grip by limiting tread flexibility. Maintaining the manufacturer-recommended pressure ensures optimal braking performance.
Tyre Wear and Braking Efficiency
Even the best tyres lose their effectiveness as they wear down. Studies indicate that when tread depth falls below 3mm, braking distances can increase by 20–30% compared to new tyres. Worn-out tyres struggle to channel water away efficiently, increasing the risk of skidding.
Key Recommendations for Safer Braking
- Choose season-appropriate tyres – Use summer tyres in warm months and winter tyres in colder climates.
- Monitor tread depth – Replace tyres before they reach the legal minimum of 1.6mm.
- Maintain proper tyre pressure – Check it monthly to ensure optimal contact with the road.
- Invest in quality tyres – While budget options may seem cost-effective, they often compromise safety.
Tyre selection directly influences braking distance, particularly in challenging weather conditions. High-performance and season-specific tyres enhance grip and reduce stopping distances, making driving safer. Regular maintenance, proper inflation, and timely replacements further contribute to optimal braking efficiency. By choosing the right tyres and keeping them in good condition, drivers can significantly improve road safety for themselves and others.
