Tyre inflation:
It is very important to check the pressure in your tyres, using a special instrument for measuring pressure, at least once a month. Insufficient or too high pressure can cause irregular, too fast wear of tyres and because of this a tyre heats up too much, more fuel is consumed and there may even arise a risk of tyre explosion. Check the tyre pressure when they are cold and have not been used for some time. Even if you have driven one kilometer, it will increase the pressure, so the results of measurement will be inaccurate. A constant pressure drop can indicate problems with the tyre or its installation problems. If you notice such situation, immediately consult a professional – a seller of tyres.
Checking of tyre tread:
Regularly check the tyre tread in order to find out when you should replace the tyres. Tyres of all passenger cars and small trucks have tread-wear indicators built right into the tread. These stripes are mounted into tread grooves in several places of a tyre. When a tyre wears out so that these stripes are clearly equated with the adjacent edges of the tread, it is time to replace the tyre. If the tread wears only in one or two places, it can mean that the tyre is inflated improperly. Here are some of the most common forms of uneven tread wear, and problems which cause them.
Tread dents: WORN PARTS
Usually this is the problem of front tyres, although the rear ones can be also damaged this way. This may indicate that your tyres are unbalanced, or that the brake and steering systems of your car are worn out.
“Saw teeth”: MISALIGNMENT
Do the edges of your tyre tread look like saw teeth or feathers? This problem can be eliminated by folding or spreading out the axes. The proper tread grooves are essential for the right operation of a tyre. If you notice that the adherence with the wet road surface have weakened or changed, maybe your tyre tread is worn out. When the tread depth is only 3 mm, the tyre should be replaced.
Wear in the center: PRESSURE TOO HIGH
When the tyre pressure is too high, all the weight falls on he center of the tread, so it wears out faster than the side parts. Uneven wear reduces the useful lifespan of the tyre. Constantly check the tyre pressure of your vehicle. The cause of improper operation of the tyre can be misalignment and mechanical problems.
Wear of both edges: PRESSURE TOO LOW
If your tyre looks this way, it might be not pumped up enough. Because of the pressure being too low the tyre wears out more on the outer edges, which reduces the lifespan of the tyre. This period is also reduced because the tyre heats up more. Eventually, this leads to an increase in fuel consumption, as resistance increases (due to the soft tyres your car has to work harder). The cause of improper operation of the tyre can be misalignment and mechanical problems.
Tyre Balancing:
Unbalanced tyres cause vibration, because of which the driver gets tired, and lead to premature, unusual tyre wear, and also create an additional load on the brakes. The tyres of your car should be balanced when they are being installed for the first time or after repair. The balance of tyres should be checked when the first signs of vibration appear.
Wheel alignment:
The wheel alignment is correct if all components of the suspension and steering systems are in good order, and if the wheels are going straight and accurate. Uneven tread wear may indicate a misalignment. This problem can be eliminated only by a professional.
Tyre replacement:
Though most people can replace tyres themselves, it can be done faster, easier and safer by professionals. A certain way of tyre replacement and its frequency should be given in your car manual. If a particular frequency is not specified, it is best to replace the tyres when the residual tread depth is not less than 4 mm.
Tyre repair:
The tyres should be repaired by trained professionals. The proper repair procedures should be carried out after removing the tyre from the wheel, so that it could be possible to make a thorough search for possible damages and patch up all the punctures, as it is required by the rules of professional repair.
