It is law that the minimum tyres tread depth is 1.6mm. The tread wear indicators molded into the base of the tread grooves are set at this depth.

Drivers found in breach of this will face a fine up around £2500 and 3 penalty points for each illegal tyre. However, by the time your tyres reach this level, the tyre’s ability to grip the road will be significantly diminished. Therefore through advice from the National Tyre Distributors Association (NTDA), We recommend that tyres should be changed when the tread depth reaches 3mm.

Some important things to think about as tread wear increases it will lead to:

  • A greater chance of aquaplaning in the wet.
  • Reduced handling characteristics and reduced control of the vehicle.
  • Longer stopping distances.
  • A greater chance of sudden tyre failure.

 

A vehicle tyre is a vehicle’s only point of contact with the road, and the contact patch area is often no bigger than the palm of your hand. Therefore it is essential to maintain overall good tyre condition. To achieve this, tyres should be checked regularly and changed when needed.  It is also vital that the right size of tyre, including the correct speed/load rating is fitted to the vehicle, balanced accurately and inflated to the correct tyre pressure.

There are numerous other reasons that tyres may be deemed unsafe and would warrant changing, such as bulges, slices, cracks and other sorts of damage.

Wheel Balancing

Incorrect wheel balance causes a vibration/wobble in the steering when driving above a certain speed. If left, incorrect wheel balance can also lead to –

  • Premature wear of tyres
  • Rapid wear of suspension parts
  • Reduction in your vehicles road handling capabilities
  • Less fuel economy

Wheel Alignment

Vehicle suspension misalignment is bad news for your tyres and bad news for your pocket.

If your suspension is misaligned the tyre is essentially being forced sideways, resulting in greater tyre scrub, excessive, irregular tyre wear and can even affect the handling and safety of your vehicle.

If wheel alignment is set correctly, tyres will last longer and control of your vehicle will be greatly improved. Some tell tale signs of suspension misalignment are excessive wear on either the inside or outside edges of your tyres and the steering wheel pulling in one direction. Wheel alignment can be knocked out for many reasons, for example, potholes, clipping kerbs and speed bumps.

TPMS: Tyre Pressure Monitoring System

Some modern vehicle have this TPMS fitted, and you may not know about it. TPMS gives you the ability to monitor your tyre pressures, without physically checking them yourself. Normally displayed on your dashboard, or as a warning message that will pop up when it notices the tyre pressures are getting low.

    Things to know:
  • We sometimes see if you have TPMS fitted by just looking at the valves on the wheel.
  • The Connection between the rotating wheel and the car is done via Radio frequency.
  • Run flat tyres, by law have to have TPMS, they also have stronger sidewalls.
  • The Biggest cause of tyre blow out is low tyre pressures (this is cause mainly from the extra heat build up)

Two types of Tyre Monitoring:

Direct & Indirect

Indirect use existing wheel speed sensors to monitor relative wheel speeds. A tyre with significant deflation will have a smaller rolling radius and hence will rotate faster. This is an indication only form of monitoring system.

Direct method relies on a permanently installed sensor inside the tyre which communicates to the body electrical system via telemetry. This remote sensing module comprises of a pressure and temperature sensor, signal processor and radio frequency transmitter and power provided by a long life Lithium battery. The Signal processor manages power consumption of the sensor so effectively that the battery life can be up to 10 years! A receiver unit is mounted close to the wheel and receives the data transmitted by the tyre sensor which includes pressure, temperature and Wheel ID. This can be transmitted via CAN to the instrument panel where detailed information can be processed and displayed to the driver about tyre pressure status.
