The best tyre tread depth gauges

Keep safe and legal on UK roads and check your tyres with the best tread gaugues

The best tyre tread depth checkers

by Seth Walton |

Checking the depth of your tyre tread may seem like a laborious and unnecessary part of car maintenance, but in truth, this job is imperative to ensure your safety while on the road.

What is tyre tread?

Road tyres have grooved patterns to displace water between them and the road, keeping your car in a straight line by maintaining grip and friction between the two.

If too much water builds up on the tyre's surface, it will break traction between the car and the road, causing the vehicle to aquaplane (a dangerous skidding motion during which the driver has no control over the car’s direction).

Tyre tread allows water to gather up within the grooves of the tyre, rather than the area contacting the road, and remove it once the tyre rotates.

Over time, tyres will wear away on the surface, reducing the tread depth until there is practically none left. To have no tread on your tyres is incredibly dangerous - and illegal.

It is UK law for road tyres to have at least 1.6mm of tyre tread across the central three-quarters of the tyre - consistent across its complete circumference - to be legal.

If you are caught out by the cops with ‘balding’ tyres beneath the 1.6mm limit, you can expect a healthy fine – up to £2,500 – and three points on your license, per tyre.

Keep the Police off your back, your license free from points and your car on the road, with a tyre tread depth gauge.

These handy gadgets will accurately inform you of the tread depth left on your car’s tyres, indicating whether you’re safe to set off or need to pay a visit to the garage. To maximise your safety, we recommend checking every couple of weeks.
