Signs of Wear and When to Replace Your Tyres
Your tyres are your car’s first line of defence when it comes to road safety. But like all components, they wear out over time. Recognising the signs early can save you money, reduce the risk of accidents, and keep your vehicle handling at its best. Here’s how Bangor drivers can tell when it’s time to replace their tyres.
1. Your Tread Depth Is Too Low
In the UK, the minimum legal tread depth is 1.6mm across the central three-quarters of the tyre. Driving on tyres below this limit is dangerous and illegal.
How to check:
The 20p test: Insert a 20p coin into the tread groove. If you can see the outer rim of the coin, the tread is likely too shallow.
Use a tread depth gauge for a precise measurement.
Tip: Many experts recommend replacing tyres when tread depth drops below 3mm for safer stopping distances in wet conditions.
2. Cracks, Bulges or Visible Damage
Inspect the sidewalls for:
- Cracks (often due to ageing or exposure to the elements)
- Bulges (usually caused by impact damage or internal weakening)
- Cuts or splits
These signs mean the tyre structure could be compromised — increasing the risk of a blowout. If you spot any of these, have your tyres checked immediately.
3. Uneven or Strange Wear Patterns
Uneven wear is a clue that something isn’t right. Possible causes include:
- Wheel misalignment
- Suspension issues
- Incorrect tyre pressures
Common signs:
- Worn edges: Often due to under-inflation
- Worn centre: May suggest over-inflation
- One-sided wear: Likely caused by misalignment
Bangor Tyre Company offers wheel alignment checks to help prevent premature tyre wear.
4. Tyre Age
Even if the tread looks fine, older tyres can become hard and brittle, especially if they’re exposed to sun or rarely used.
Most manufacturers recommend changing tyres every 5 to 6 years.
You can check the tyre’s age by reading the DOT date code on the sidewall (the last four digits show the week and year of manufacture).
5. Persistent Loss of Pressure
If you’re constantly topping up tyre pressure, it may be more than a slow puncture. Common causes include:
- Valve damage
- Corroded wheel rims
- A poor seal between the tyre and rim
Bring your car in and we’ll identify and fix the issue — or advise if a replacement is necessary.
6. Strange Vibrations or Noises
Vibrations through the steering wheel or odd noises can suggest:
- A flat spot from sudden braking
- Tyre imbalance
- Internal tyre damage
These symptoms shouldn’t be ignored, as they may lead to further tyre or mechanical damage.
