Your vehicle must be fitted with the correct type of tyre for its use. The legal limit for minimum depth of the tread on all car and van tyres is 1.6 millimetres, across the central 3 of the tread around the complete circumference of the tyre. The tyres fitted to your vehicle must be of the same construction on the same axle i.e Radial, Crossply or Bias Belted.
We recommend you change your tyres at around 3mm as leaving them any longer will make a major difference to the handling and braking capabilities of your vehicle.
We suggest you call in for a free monthly tyre and pressure check to avoid the chance of penalty points (3 points per illegal tyre) or up to £2,500.00 (per tyre) in fines.
There are several signs to look for which will help you decide whether it's time to change such as lack of grip and braking ability. Tyre age is another problem as the tread may be ok, however perishing on the sidewall can cause blebbing and ultimately a blow out. Ageing tends to occur most when your car is used infrequently.
Again we suggest you call in for a free tyre depth and pressure check on a monthly basis.
