Your Complete Guide to Staying Safe and Informed on the Road

Tyres are one of the most important – and often most overlooked – parts of your vehicle. They’re the only point of contact between your car and the road, which means they play a crucial role in everything from handling and braking to fuel economy and comfort.

Whether you’re a first-time car owner or just want to brush up on the basics, here’s everything you need to know about tyres, explained clearly and simply.

1. Understanding Tyre Sizes and Markings

Ever looked at the side of your tyre and seen something like 205/55 R16 91V? Here’s what it means:

• 205 – Width of the tyre in millimetres

• 55 – Aspect ratio (height as a percentage of width)

• R – Radial construction (most modern tyres are radial)

• 16 – Diameter of the wheel (in inches)

• 91 – Load index (how much weight the tyre can carry)

• V – Speed rating (maximum speed the tyre can handle safely)

These markings help you ensure you’re fitting the correct tyres for your vehicle.

2. Types of Tyres

🛣️ Summer Tyres

Optimised for dry and wet conditions in warmer temperatures. Offer excellent grip and performance.

❄️ Winter Tyres

Made with special rubber compounds and tread designs to provide traction on snow, ice, and in cold temperatures.

🍂 All-Season Tyres

A blend of summer and winter tyre features. Ideal for UK drivers who want a year-round solution and don’t face extreme weather.

🚗 Performance Tyres

Designed for high-speed handling and superior grip. Commonly used on sports and luxury cars.

🚙 Run-Flat Tyres

Allow you to continue driving for a short distance even after a puncture—enough to reach a garage safely.

3. Tyre Maintenance Basics

Proper tyre care doesn’t just keep you safe—it saves you money too.

✅ Check Tyre Pressure Monthly

Under- or over-inflated tyres wear unevenly and reduce fuel efficiency. Always check your pressure when tyres are cold.

✅ Inspect Tread Depth

UK law requires a minimum tread depth of 1.6mm across the central three-quarters of the tyre. Use a 20p coin to check—if you can see the outer band, it’s time for a replacement.

✅ Rotate Your Tyres

Switching tyres between front and rear can extend their life. Aim to rotate every 6,000 to 8,000 miles.

✅ Wheel Alignment and Balancing

Poor alignment leads to uneven wear and poor handling. Have your wheels aligned and balanced regularly.

4. When to Replace Your Tyres

Look for these signs:

• Cracks in the sidewall

• Bulges or blisters

• Uneven tread wear

• Excessive road noise or vibrations

• Visible steel cords or damage

Even if they look fine, tyres older than 5–6 years may become brittle and unsafe—check the DOT date code on the sidewall for the year of manufacture.

5. Choosing the Right Brand

There are plenty of excellent tyre brands on the market. Some of the most trusted include:

• Goodyear – Known for premium quality, long lifespan, and performance across all conditions.

• Hankook – Offers a great balance of value, comfort, and durability.

• Michelin – Famous for innovation and longevity.

• Continental – Excellent for braking and wet grip.

• Pirelli – Ideal for high-performance and sports vehicles.

Choosing a tyre brand depends on your driving style, budget, and the type of car you drive.

6. Tyres and Safety

Your tyres affect braking distance, cornering grip, hydroplaning resistance, and more. Worn or incorrectly fitted tyres are not just dangerous—they can also result in:

• Fines and penalty points

• MOT failure

• Voided insurance

Safe tyres = safe journeys.

7. The Eco Angle: Fuel Efficiency and Emissions

Modern tyres are designed with low rolling resistance, which improves fuel efficiency and reduces carbon emissions. Many tyres now come with EU tyre labels showing performance in:

• Fuel efficiency

• Wet grip

• External noise levels

Choosing eco-friendly tyres can help your wallet and the planet.

In Summary

Tyres may not be the flashiest part of your car, but they are undeniably one of the most important. Understanding how to choose, inspect, and care for your tyres ensures better performance, improved safety, and peace of mind every time you hit the road.

Whether you’re cruising through the city or exploring country lanes, make sure your tyres are ready for the journey.
