Tyre tread depth is one of the most critical aspects of tyre performance and safety. The tread refers to the rubber on the tyre’s surface that makes contact with the road. Over time, this tread wears down, reducing the tyre’s ability to grip the road effectively.
Why Tread Depth Matters:
- Water Displacement: Adequate tread depth helps disperse water on wet roads, preventing your car from sliding uncontrollably (known as hydroplaning).
- Traction: Tread gives your tyres the necessary grip on the road. The deeper the tread, the better the grip, especially in adverse conditions such as rain or snow.
- Legal Requirements: In most countries, the legal minimum tread depth is 1.6mm. Driving on tyres with less tread is illegal and unsafe, as they offer almost no grip in wet conditions.
How to Check Tyre Tread Depth:
Use a tread depth gauge or the “coin test” (inserting a coin into the tyre grooves) to check your tyre tread. Regular checks will help you maintain safe driving conditions and know when it’s time to replace your tyres.
