As vehicles frequently carry heavy loads, it's essential that tyres are inflated to the correct pressure. If a tyre is under-inflated excess heat builds up within a tyre, which greatly increases the likelihood of a rapid deflation.
This is a major safety risk as it can cause loss of control and can also put other road users at risk.
Drivers should ensure that tyres are inflated to the correct pressure, which can be found in the vehicle handbook.
Tyres are engineered to work in harmony with the vehicle's braking, steering and suspension systems. If a tyre is under-inflated it contains insufficient air to support the weight of the vehicle. This can greatly affect acceleration, braking and cornering, potentially making unsafe driving.
By keeping tyres properly inflated, drivers can travel further on each tank of fuel and reduce their CO2 emissions.
A vehicle's load is supported in the shoulder area of the tread, therefore under-inflated vehicles experience rapid wear in this area. Driving on over-flated tyres results in higher wear in the centre of the tread. Keeping tyres inflated to the recommended pressure for the vehicle and load ensures a even wear rate, helping the tyres last longer.
1. Use a reliable and accurate pressure gauge to check the pressure of van tyres at least once a month or before a long trip.
2. Check the pressure in all tyres not forgetting to check any spare tyre(s) as well.
3. Tyre pressure should be checked against the vehicle manufacturer's recommended operating pressures for the load being carried.
4. Check the pressure when tyres are cold or when the vehicle has travelled less than two miles.
5. When checking pressures, give the rest of the tyre a thorough visual inspection. Remove any stones and other objects embedded in the tread. Look out for any cuts,lumps or bulges.
6. If you are unsure on any aspect of tyre pressure or tyre condition take your vehicle to an approved fitting centre and speak to the experts
1. Clean the dirt from the valves and make sure that caps are fitted to the valves on each wheel.
2. Remove any stones and other objects embedded in the tread.
3. Look out for any bulges, lumps or cuts to the tread and sidewalls as well as any evidence of surface cracking or crazing. Any damage should be inspected by a tyre professional.
4. Repairs to van tyres must only be carried out by a tyre specialist, and must be done in accordance with the current British Standards.
5. The suspension alignment should be checked and corrected as necessary if the tyres show signs of excessive, uneven or irregular wear.
6. Any unusual vibration or air loss must be examined immediately by a tyre professional, as these could be signs of potential tyre failure.
Many drivers buy part worn tyres because they believe they offer better value for money. Legislation exists which permits the sale of part worn tyres subject to them meeting criteria. However this isn't always the case, drivers should look at the cost per mm of useable tyre and that part worn tyres that do not meet these legal requirements pose a serious safety risk to you, your passengers and other road users.
The Requirements under The Motor Vehicle Tyres (Safety) Regulations 1995 (reg.7.) for sell of part worn tyres are as follows;
1. The outer visual condition must be free of bulges, cuts or lumps.
2. Any repair must have been carried out in accordance with the BS AU 159.
3. Tyres must have passed an inflation test.
4. Current UK law requires that the tyres must have a minimum depth of 2 millimetres, across the central ¾ of the tread around the complete circumference of the tyre.
5. Part worn tyres which have not been retreaded must clearly show the 'E' mark alongside 'Part-Worn' at least 4mm high.
