Figuring out when to get new tyres can be a bit challenging. Since tyres can be pricey it's easy to want to hold off on replacing them for a little longer especially when you have other things on your mind. However the timing for changing tyres depends on factors like your driving style, road conditions, weather and of course how worn out the tyres are. So how can you tell it's time for a change? Here are the key signs to look out for:
1. Tread Wear
Tyres come with built in indicators to show you when they are due for replacement. Keep an eye out for arrowhead shapes on the sidewall; these indicators are positioned near rubber bridges between the treads. If the tread wears down to the height of these bridges it's a sign that you should head to your tyre dealer without delay.
2. Asymmetric Tyre Wear
Occasionally a tyre can wear unevenly due to problems with alignment or suspension. One side of the tyre might still have tread while the other side could be worn down to its limit. In these situations it’s important to not replace the tyre but also fix the underlying issue like alignment or suspension repair.
3. Hardened or Cracked Tread
If you don't use your car frequently the rubber on the tyres can become stiff as time goes by. Take a look for any cracks on the tread surface. While some small surface cracks are common, more noticeable cracks particularly on the sidewalls suggest that the rubber has hardened considerably. You may still be able to use these tyres for journeys but if you intend to drive long distances or at speeds it's advisable to get them replaced.
4. Damaged Sidewalls
Most new cars are fitted with tyres that rely on the strength of their sidewalls. If you drive on roads or hit a pothole unexpectedly it can cause damage to the sidewall resulting in bubbles or cracks. Although repair shops provide sidewall patches they are not a guaranteed fix. Opting for a tyre replacement is a safer and more dependable choice.
5. Tyre Age
As tyres get older they become less flexible and lose their grip even if they look fine on the outside. Older tyres are not as efficient, soft compound tyres might not show signs of cracking but their performance still diminishes with time. It's generally a good idea to steer clear of purchasing tyres that are more than six months old and to replace them after three years or once you've driven 40,000 kilometers.
6. Environmental Parameters
The performance of tyres can be influenced by factors such as weather conditions. For instance if your tyres are getting worn out it might be wise to replace them before the rainy season starts to ensure good traction on slippery roads. Moreover driving at speeds can lead to faster tyre wear necessitating more frequent replacements for safety purposes.
7. Tyre Vibration:
Excessive vibration while driving could be a sign that your tyres need to be replaced. While some vibration is normal, especially on rough roads, unusual shaking or wobbling can indicate internal tyre damage, an out-of-balance wheel, or even problems with suspension. Ignoring this can not only reduce comfort but also affect your vehicle's safety. It’s important to get your tyres checked by a professional if you notice significant vibration.
8. Frequent Air Leaks:
If you find yourself constantly refilling air in your tyres, it might be a sign of wear or damage. Small punctures or leaks can be repaired, but if you’re noticing consistent air pressure loss without obvious damage, the tyre might have weakened and should be replaced.
9. Reduced Fuel Efficiency:
Worn-out tyres can increase rolling resistance, which means your car needs to work harder to move. This can result in lower fuel efficiency. If you notice that you’re making more trips to the gas station without changing your driving habits, it could be a sign that your tyres are near the end of their lifespan and should be replaced to improve performance and efficiency.
10. Decreased Traction in Wet Conditions:
Over time, tyre treads lose their ability to channel water away, increasing the risk of hydroplaning in wet conditions. If you notice a loss of traction during rain or that your car is skidding more frequently, it's a good indicator that the tread depth has worn down to unsafe levels and it's time for new tyres.
