How to Check Your Tyre Tread Depth at Home

A Simple Guide for Bangor Drivers

Your tyres are the only part of your car in contact with the road, so ensuring they have enough tread depth is crucial for safety. Worn-out tyres can reduce grip, increase stopping distances, and even result in a failed MOT. Thankfully, checking your tyre tread depth at home is quick and easy. Here’s how Bangor drivers can do it themselves.

Three Easy Ways to Check Your Tread Depth at Home

1. The 20p Coin Test

The 20p test is a simple and effective way to check your tyres:

  • Take a 20p coin and insert it into the grooves of your tyre tread.

  • If you can see the outer band of the coin, your tread is likely below 1.6mm, meaning it’s time to replace your tyres.

  • Check multiple spots around the tyre to ensure even wear.

2. Using a Tread Depth Gauge

For a more accurate reading, you can use a tread depth gauge, available online or in auto shops:

  • Place the gauge’s probe into the tyre groove.

  • Press the gauge flat against the tread and read the measurement.

  • If the reading is below 1.6mm, replace your tyres immediately.

3. Checking the Tyre Wear Indicators

Most modern tyres have built-in wear indicators:

  • Look for small raised bars inside the grooves of your tyres.

  • If the tread is flush with these bars, your tyres have reached the legal limit and need replacing.

Signs You Need New Tyres

Even if your tread depth is above the legal limit, other warning signs mean it’s time for new tyres:

  • Uneven wear – Could indicate alignment or suspension issues.

  • Cracks or bulges – A sign of ageing or damage.

  • Reduced grip in wet conditions – A sign your tyres are losing effectiveness.
