For every vehicle owner, understanding when to replace tyres is crucial for maintaining safety, performance, and efficiency on the road. Tyres are the only point of contact between your vehicle and the road, and their condition can significantly affect your driving experience. Here are five signs that indicate it's time to consider changing your tyres.

Sign #1: Tread Depth is Below Legal Limit

Tread depth is a critical factor in ensuring your tyres provide adequate grip, especially in wet conditions. A simple way to measure tread depth is by using a tread depth gauge or the 'penny test'. If the tread is worn down to the point where the coin's design is visible, it's time for a replacement.

In Estonia, the legal minimum tread depth is 1.6 millimeters. Driving with tyres below this limit is not only illegal but also dangerous, as it increases the risk of hydroplaning and accidents.

Sign #2: Visible Damage to the Tyres

Visible damage such as cuts, bulges, or punctures can compromise the structural integrity of your tyres. Regular inspections can help identify these issues early on.

Not all visible damage requires immediate tyre replacement, but significant damage like deep cuts or large bulges often means the tyre is no longer safe to use.

Sign #3: Tyres are Over 5 Years Old

Even if your tyres look fine, rubber compounds deteriorate over time. Manufacturers typically recommend replacing tyres every 5 to 10 years, regardless of tread depth.

The age of a tyre can be determined by the DOT code on its sidewall, which includes the week and year of manufacture.

Sign #4: Vibration or Unusual Noises While Driving

Vibrations or unusual noises while driving can be a sign of uneven tyre wear, misalignment, or balance issues. These symptoms should not be ignored as they can indicate serious tyre problems.

If you experience persistent vibrations or noises, it's best to have your tyres checked by a professional to determine if they need to be replaced.

Sign #5: Poor Vehicle Handling or Increased Stopping Distance

Poor vehicle handling, such as difficulty steering or maintaining traction, can be a sign of worn tyres. Similarly, if you notice an increased stopping distance, it's time to check your tyres.

Good tyres are essential for safe braking. Worn tyres can significantly increase the distance required to come to a complete stop, putting you and others at risk.
