1. Do not use tyres with a tread depth of less than 1.6mm. Apart from being illegal, tyres with low levels of tread will slide easily, suffer from extended braking distances and will be more susceptible to rupturing. In wet conditions the vehicle will aquaplane making braking and handling almost impossible.
2. Make sure air pressures are correct. Low air pressure generates heat which can result in the rubber and cord separating, which in turn leads to the cord becoming cut and puncturing the tyre. Low pressure also results in excessive wear on the edge of the tyre, shortening the tyre's life. Excessive pressure, meanwhile, results in unpredictable handling in addition to which, if the tyre suffers an impact, it's easily ruptured and cut. If you brake hard, the tyre may skid, which reduces tyre life as the centre of the tread becomes worn. Check tyre inflation pressures at least twice a month. Always check pressures when tyres are cool and maintain the pressure recommended by the vehicle manufacturer.
3. Remove objects from damaged tyres. Driving with objects such as stone in the tread groove, or with a nail stuck in the tread can puncture or rupture the tyre. You should change or repair the tyre immediately on discovering any damage to avoid any further damage to the carcass.
4. Treat abnormal tyre wear immediately. To assure normal wear you should check air pressures and alignment and rotate the tyres regularly. Advise customers to avoid bad driving habits such as sudden acceleration, braking and cornering.
5. Check the spare tyre. Check the spare tyre's air pressure, existence/non existence of damage and the depth of remaining tread.
6. Never mount radial tyres on the same axle as non-radial tyres or radial tyres on the front axle when non-radial tyres are mounted on the rear axle. These conditions are likely to cause vehicle instability resulting in a sudden loss of control and serious injury.
7. Ensure wheel nuts are securely tightened.
8. Never overload tyres. The maximum load and inflation pressure of the tyres are moulded into the sidewall. Also, remember; the tyre is capable of carrying the maximum load only if it is inflated to its maximum air pressure.
9. Do not use detergents or chemicals containing petroleum products for cleaning or polishing tyres.
10. Never fit used tyres unless their past history is known. Tyres age even if they have not been used or have only been used occasionally. Cracks in the tread or in the sidewall rubber, sometimes accompanied by deformation of the carcass, are a sure sign of aging.
11. Punctured tyres must always be removed from the wheel to check for secondary damage.
12. If it is necessary and feasible to repair a tyre, it must be carried out by a tyre specialist as soon as possible to avoid any structural deterioration. All tyre repairs must be entrusted to a tyre repair specialist.
1. As per central Motor vehicle regulations (CMVR) car tyres must have a minimum of 1.6mm of tread in a continuous band throughout the centre of the tread width and over the whole circumference of the tyre.
2. To help recognise when tyres are nearing the legal limit, tyres are manufactured with tread wear indicators in the grooves.
3. However, despite the law, it is universally recognised in the tyre industry that the legal limit is wholly insufficient to protect drivers in adverse driving conditions.
4. Drivers are therefore recommended to consider replacing their tyres when the tread depth reaches 3mm. Correct Air Pressures
Setting and maintaining the correct air pressures is the first step to obtain optimum performance and life from tyres. Incorrect Inflation
1. Over inflation reduces the ability of the tyre to absorb road shocks resulting in a much harsher ride. Excessive over inflation may lead to impact fracture or other casing failures. Over inflation will also cause excessive wear of the centre of the tyre.
2. Under inflation allows excessive flexing of the tyre, causing excessive internal heat to build up, eventually weakening the casing and causing damage. Under inflation will also cause excessive wear on the shoulder of the tyre resulting in heavy steering and poor handling.
3. Excessive pressure on the shoulder area will increase wear and reduce stopping distance. Tyre Rotation
Front Wheel Drive
Rear Wheel Drive
Rotate your tyres every 5000km to achieve equal rate of wear.
