Tracking / Alignment

Incorrect wheel alignment (tracking) is one of the main reasons for premature tyre wear on vehicles.

The most common signs of incorrect wheel alignment are usually seen as irregular, "feather type" wear across the width of the tread. This is caused by the wheels failing to run in the correct direction and having to be "pulled" back into line as the vehicle travels. This pulling effect leads to the tyre scrubbing on the road surface, resulting in irregular wear and a tendency for the vehicle to pull to one side. It can also have a detrimental effect on vehicle fuel consumption due to the increased rolling resistance of the incorrectly aligned wheels.

Correctly aligned wheels extend tyre life and improve fuel efficiency. They also help safe steering of the vehicle and a comfortable ride.

Causes of misalignment are hitting potholes, bumps, or could be caused by loose steering or worn shock absorbers or worn steering components. Your car's wheels should be aligned at least once a year or every 10,000 miles,(whichever is earlier).

Take you vehicle for a professional tyre inspection at Ulster Tyres.


Whilst a puncture is usually more of an inconvenience and unwanted expense, the dangers involved with a tyre failure at high speed are far more serious, ie loss of control.

Punctured tyres must be dis-mounted and inspected internally before any repair is carried out. Anti puncture sprays can temporarily plug small holes but are not long-term repair solution. You must take your tyre to be checked by a professional tyre fitter.

Replace a punctured tyre if:

  • The wire casing is exposed
  • The tread depth is below the legal wear limit (1.6mm)
  • There is damage from it being driven flat
  • The tyre sidewall is damaged
  • Deterioration of tyre rubber
  • Previous tyre repairs have failed

Wheel Balancing

Wheels that are not balanced or are out of balance usually produce a vibration that is uncomfortable to drive in and results in premature wearing of suspension and steering components, rotating parts and tyres.

Correctly balanced wheels eliminates vibration and avoids premature wear on your tyres and ensure smooth and enjoyable driving, ultimately saving you time and money.

The first sign that your wheels may be out of balance is when your steering wheel starts to wobble above a certain speed. A driver may not always sense an imbalance at the steering wheel, this is why balancing is equally important for both front and rear wheels.

Wheels are balanced on a wheel-balancing machine. The machine rotates the tyre and wheel assembly and automatically calculates the weight and location of the balance counter weight.
