Check Tread Depth
Legal Limit: In most regions, the legal tread depth limit is 1.6mm. However, for optimal safety and performance, it’s recommended to change your tyres when the tread depth reaches 3mm.
Tread Wear Indicators (TWI): Most tyres have built-in tread wear indicators that show when your tread is getting too low. If these markers are level with the tyre tread, it’s time for new tyres.
Visible Damage
Cracks or Cuts: Inspect your tyres regularly for cracks, cuts, or bulges on the sidewall. Any visible damage can compromise safety and requires immediate attention.
Punctures: Small punctures can sometimes be repaired, but if you experience frequent punctures or a large tear, you may need to replace the tyre entirely.
Irregular Wear
Uneven Wear Patterns: Uneven tread wear could indicate issues like improper alignment, unbalanced tyres, or suspension problems. If you notice significant differences in wear between tyres, it might be time for replacements, along with a check of your vehicle’s alignment.
Age of the Tyres
Tyre Age: Even if the tread depth looks fine, tyres should generally be replaced every 5-6 years due to aging rubber. The rubber hardens over time, reducing traction, especially in wet conditions.
Manufacture Date: Check the sidewall of your tyres for the DOT code. The last four digits represent the week and year of manufacture. For example, ‘2219’ means the tyre was made in the 22nd week of 2019.
Frequent Loss of Pressure
If you notice that one or more tyres are losing air pressure faster than the others, it could be a sign of a slow puncture, valve issues, or internal damage that requires tyre replacement.
Poor Handling and Vibration
If your car is pulling to one side or you experience unusual vibrations, it might be a sign that your tyres are worn or damaged. Worn tyres can reduce your car’s handling and safety, particularly in bad weather conditions.
Mileage Considerations
High Mileage: Depending on the type of tyres and your driving habits, tyres typically last between 40,000 and 80,000 kilometers. If you’ve been driving for a long time on the same set, it may be time to replace them regardless of their visible condition.
