When Do You Need to Change Car Tyres?

s play a crucial role in ensuring safety, fuel efficiency, and overall vehicle performance. But how do you know when it’s time to replace them?

At ChipsAway, we believe regular tyre maintenance and timely replacements are key to keeping you safe on the road. In this guide, we’ll outline the key signs that indicate when you need to change your tyres.

1. Tread Depth is Below the Legal Limit 

One of the clearest indicators that your tyres need replacing is the tread depth. In the UK, the legal minimum tread depth is 1.6mm. If the tread is worn below this limit, your tyres lose grip, especially in wet conditions, making it dangerous to drive.

You can easily check this by using a tread depth gauge or the “20p test,” where the rim of a 20p coin should be covered when inserted into the tyre’s tread groove. If it isn’t, it’s time for a change.

2. Visible Damage 

Any visible damage such as cuts, cracks, bulges, or punctures in your tyres can compromise their structural integrity. Tyre bulges occur when the internal structure is damaged, which could lead to blowouts. If you spot any visible damage, it’s important to replace the tyre immediately to avoid accidents.

3. Uneven Tread Wear

If your tyres are wearing unevenly, it might be a sign of improper wheel alignment, under-inflation, or suspension issues. Uneven tread wear can reduce your tyres’ grip and handling ability. If you notice bald patches on one side or more wear on the centre of the tyre, consider replacing them and addressing the underlying issue.

4. Age of the Tyres 

Even if your tyres look in good condition, age plays a role in their effectiveness. Most tyre manufacturers recommend replacing tyres every six years, regardless of tread wear. Over time, the rubber hardens and can develop cracks, reducing grip and increasing the risk of tyre failure. You can check the age of your tyres by looking at the DOT code on the tyre’s sidewall.

5. Frequent Loss of Tyre Pressure

If your tyres are losing pressure frequently, it might be due to a slow puncture or damage to the tyre’s structure. Driving with under-inflated tyres can be dangerous and lead to faster wear. If you need to inflate your tyres more often than usual, it’s worth getting them checked by a professional and considering a replacement.

6. Vibration While Driving

If you feel unusual vibrations or shaking while driving, especially at higher speeds, it could indicate tyre problems or wheel alignment issues. Vibration can signal tyre imbalance, damaged tyres, or even issues with the vehicle’s suspension. If left unchecked, this can cause further damage to your tyres, so it’s best to have them inspected and replaced if necessary.

Tips on Tyre Care and Maintenance

Proper tyre care can help you avoid premature replacements and improve the lifespan of your tyres:

• Check Tyre Pressure Regularly: Keeping your tyres inflated to the recommended level ensures even wear and reduces the risk of blowouts. Under-inflated or over-inflated tyres can cause excessive wear on certain areas of the tyre.
• Rotate Your Tyres: Regular tyre rotation helps distribute wear evenly across all tyres. This prolongs their life and improves vehicle performance. Aim to rotate your tyres every 6,000 to 8,000 miles.
• Align Your Wheels: Poor alignment causes uneven tread wear and reduces the lifespan of your tyres. Ensure your wheels are aligned properly to avoid damage.
• Balance Your Tyres: Unbalanced tyres cause vibration, which leads to uneven wear. Balancing tyres after installation or rotation ensures smoother driving and longer-lasting tyres.

Choosing the Right Tyres for Your Car

Different tyres suit different driving conditions, so it’s important to choose the right ones for your needs. Here are a few common types of tyres and their benefits:

• All-Season Tyres: These provide good performance in most weather conditions. They’re ideal for moderate climates and deliver a balanced mix of handling, comfort and longevity.
• Winter Tyres: Designed for cold weather, these tyres offer superior grip on snow, ice, and wet surfaces. They are essential for areas that experience heavy winters but can wear out quickly in warmer temperatures.
• Performance Tyres: If you prioritise handling and speed, performance tyres offer enhanced grip and precision. However, they tend to wear out faster and may not perform well in wet or cold conditions.
• Run-Flat Tyres: These allow you to drive a short distance after a puncture, giving you time to reach a garage. However, they are typically more expensive than standard tyres.

When in Doubt, Check with a Professional 

Knowing when to change your car tyres is essential for maintaining the safety and performance of your vehicle. From checking tread depth to selecting the right type of tyre for your driving conditions, regular tyre care is key.
