Care & Safety Tyre
Tyre care and tyre safety
Here at Wythall Tyres and Exhausts in Wythall you can get a few useful tips on tyre care and storage of tyres and wheels.
Filling pressure for tyres
Important factors, e.g. Driving safety, fuel consumption and tyre wear are decisively influenced by the tyre inflation pressure. Due to diffusion through the sidewall, a tyre always loses some air. Although the proportion is negligible, the air loss accumulates to a dangerous level over time. The consequences: lateral forces in the tyre are no longer sufficiently available, the vehicle reacts retarded to steering movements, the straight line and the braking distance are deteriorating.
If a tyre is filled with insufficient air, the pressure distribution of the wheel load is greatly distributed to the outer edges and reduced in the center of the surface. Due to the different distribution of forces, depending on the speed and weight of the vehicle, there is sometimes a strong sweeping movement with heat developments of over 150 ° C. In the worst case, the material overheats in the shoulder area, the substructure loses its strength, parts of the tread and belt are detached.
The air pressure should always be checked with cold tyres as it increases by up to 0.5 bar due to the heating of the tyre. Information on the correct air pressure can be found in the fuel filler flap, the door handle or in any case in the operating instructions of the vehicle. For some years now, special sealing gases have been offered as tyre fillings, which are mainly used in long-distance transport. These gases do not escape through the side wall and can hold the filling pressure once set for about one year. However, damage to the tyre or to the valve can not be ruled out and, above all, can not be compensated for. The safest and most cost-effective method is the regular manual check of the air pressure at the service station. Do not forget the spare wheel, which you should occasionally check. The air pressure should be 0.5 bar higher than the service tyre.
The right tyre storage
Even if your tyres are not in use, you may be exposed to numerous hazards. Tyres should never be stacked on top of each other for a long period when they are not mounted and inflated. Do not stack items on your tyres. Avoid the proximity of open fire or glowing objects, as well as material that generates sparks (welding equipment), electrical discharges, or ozone (battery chargers). It is recommended to wear protective gloves when handling tyres.
Tyres should be stored as follows:
In a ventilated, dry and tempered room without direct sunlight and weather influences.Keep away from chemicals, solvents or hydrocarbons that may damage the rubber.Do not store in close proximity to objects that can damage or damage the tyre (metal tips, wood, etc.)
If possible, do not stack the tires over an extended period of time if they are not mounted and inflated. Do not put heavy objects on the tire.If you still stack your tyres, make sure that they do not deform and change the position of the tyres from time to time.
For long-term storage, the tyres should be stored vertically in shelves, at least 10 cm from the ground. Turn the tyres slightly once a month to avoid deformation. Regularly check the tyre pressure and keep the pressure recommended by the manufacturer.Service life of tyres
The life of a tyre depends on the vehicle, the driving style and many other factors and is referred to as running performance. In the case of vehicles with front-wheel drive, the running power of the rear tyres can be three times as high as that of the front tyre. It should be noted that the legal residual profile depth is 1.6 millimeters. However, tyre experts recommend changing the summer tyre at 3 mm and the winter tyre at 4 mm profile depth.
The right wheel change
After approximately 6000 to 10000 miles, you should carry out a front-rear wheel change. As a result, the tyres are evenly distributed and can be replaced at a later stage. However, if you only have two new tyres installed, they always belong to the rear axle. Here the stabilization of the rear axle and thus the safety is the most important.
