Your car’s tyres are the only point of contact between your vehicle and the road, making them one of the most critical components for safety, performance, and comfort. Over time, even the best tyres wear down and lose their grip, putting you and your passengers at risk. But how do you know when it’s time to replace them? At Siri Cars and Tyres, we believe that understanding tyre health is key to a safer and smoother driving experience.
1. Tread Depth is Too Low
One of the most obvious signs your tyres need replacing is worn-out tread. Tyre tread helps maintain grip on the road, especially in wet conditions. If the tread depth is below 1.6 mm, it’s time to replace your tyres. You can easily check this using a tread depth gauge or even the coin test — insert a coin into the tread grooves; if you can see most of the coin, your tread is too low.
2. Cracks or Bulges on the Sidewall
Inspect the sidewalls of your tyres regularly. Cracks, cuts, or bulges may indicate internal damage or ageing rubber. These issues can lead to tyre failure while driving, especially at high speeds. If you notice any abnormalities, it’s best to have your tyres inspected by a professional immediately.
3. Uneven Wear Patterns
If your tyres are wearing out more on one side than the other, it could be due to poor alignment, unbalanced tyres, or suspension problems. Uneven wear shortens tyre lifespan and can cause your car to pull to one side. Replacing worn tyres and correcting the root cause will improve both safety and driving comfort.


4. Vibrations While Driving
Excessive vibrations while driving may be a sign of tyre imbalance, internal tyre damage, or even issues with the suspension. While some vibration is normal, especially on rough roads, unusual shaking is often a warning sign that your tyres are no longer in optimal condition.
5. Tyre Age
Even if your tyres look fine on the outside, they can degrade over time. Most manufacturers recommend replacing tyres every 5 to 6 years, regardless of tread depth. Rubber ages and hardens, which reduces grip and increases the risk of cracks and blowouts.
6. Increased Stopping Distance
If you’ve noticed your car takes longer to stop than it used to, your tyres might be to blame. Worn-out tread significantly affects braking performance, especially on wet or slippery roads. Replacing your tyres can help restore safe stopping power.
