How to Check Tyre Tread Depth

Your car's tyres are its only point of contact with the road, making their condition essential for both your safety and driving experience. In this comprehensive guide, we'll walk you through everything about tyre tread depth, and share tips to ensure your vehicle is road-ready.

Why is Checking Tyre Tread Depth Important?

Tyre tread depth plays a critical role in your vehicle's performance and safety. A few key reasons why it's vital to regularly check your tyre tread depth are:

  1. Traction: The UK's frequent rain and occasional snow require tyres with adequate tread depth to maintain a strong grip on slippery roads.

  2. Braking: Worn-out tyres have reduced braking efficiency, which can lead to longer stopping distances.

  3. Hydroplaning Prevention: Proper tread depth helps channel water away from the tyre's contact patch, reducing the risk of hydroplaning.

  4. Road Safety: Tyres with adequate tread are essential for safe driving, helping you avoid accidents and maintain control in challenging situations.

  5. Compliance with UK Law: It's not just a matter of safety; it's also a legal requirement in the UK to have a minimum tread depth of 1.6 millimetres across the central three-quarters of the tyre's width.

How to Check Tyre Tread Depth

  1. Use a Tyre Tread Depth Gauge:

    A tyre tread depth gauge is a precise tool designed for this purpose. To check your tread depth accurately, follow these steps:

    a. Insert the gauge into the grooves of the tyre tread.

    b. Read the measurements displayed on the gauge. The tread depth should be at least 1.6 millimetres to ensure both safety and legal compliance in the UK.

  2. The 20p Test:

    This is a simple DIY method to assess your tyre tread depth. Here's a quick demo of it.

    a. Insert a 20p coin into the tread groove. 

    b. If you can see the outer band of the 20p coin, your tread depth is below 1.6 millimetres, indicating that it's time to replace your tyres.

  3. Check Tread Wear Indicators:

    Most tyres have tread wear indicators, which are raised bars of rubber located at regular intervals in the main grooves. When the tread wears down to the level of these indicators, it's time to replace the tyre.

  4. Refer to Your Vehicle's Manual:

    Your vehicle's manual may provide specific recommendations for the minimum acceptable tread depth for your tyres, which can vary between different types of vehicles.

Tips for Maintaining a Healthy Tyre Tread

  1. Regular Inspections: Make it a routine to check your tyre tread depth at least once a month, especially given the UK's ever-changing weather.

  2. Proper Inflation: Maintain the correct tyre pressure to ensure even wear and optimal performance, especially when transitioning between different weather conditions.

  3. Rotate Your Tyres: Regularly rotate your tyres to promote even tread wear across all four wheels.

  4. Wheel Alignment: Ensure your vehicle's wheels are properly aligned to prevent uneven wear on the edges of the tyres.

 That’s how quick and easy it is to check your tyre tread and maintain them. But if there’s anything you’re not sure about, just ask our peers at Tire Streets.
