Advice 1: How to determine tire wear

The reason for the huge number of accidents and road accidents is failure to replace worn-out motorists tire.So if you are the owner of the car, it should clearly follow the rule: if the rubber "bald", it must be replaced. But how to determine whether you need tyres to be replaced or not? There are several reliable ways to determine the degree of wear of the tires of your car.
You will need
  • - measuring tire tread
  • - line
  • - Vernier caliper.

The easiest way to determine the tire wear with the help of the device measuring tire tread. This affordable and easy to operate device can be purchased at almost any parts store or service center where your car is serviced.In order to determine the degree of tire wear, turn on the meter and place it in the groove of the tread. Then take a look at the numbers that will appear on the screen. If you have winter tires, the device should show not less than 4 mm residual thickness of the rubber, if the summer - not less than two millimeters. If the readings of the meter protector less, you need to replace the tires.

The degree of tire wear can also be defined manually using calipers and a ruler.
It is necessary to measure with a caliper the height of the tread. You do this by placing the needle in the groove Vernier caliper, measure the distance from the bottom of the groove to its top edge. Then remove the caliper and with a range of calculate how much would be the distance in millimeters. Criteria for the evaluation of wear the same as when measured with a meter tread: four and two millimeters respectively.

On some models, tires, e.g. tire manufacturing, Michelin and Nokian on the inner part of the protector marked numbers, which are gradually disappearing, showing the degree of wear rubber. Figure 8 refers to eight millimeters of the residual thickness, 6 - six millimeters, and so on. Focusing on these figures, you will be able not to miss the moment when the tires need replacement.

Advice 2: How to determine the wear of automobile tires

Check the wear of tires is one of the most important events in terms of car care. Timely inspection of the condition of the rubber will help avoid accidents on the road, extra costs, and even save your life and the lives of your passengers. A reasonable solution is to periodically seek the advice of professionals, however, you can learn to determine the degree of wear on their own. There are several reliable ways.
Instruction
1
Leading tire manufacturers usually specify the rate of mileage to each of the models. This is a different value, and they are very relative. A lot depends on the quality of the source material, the condition of the road surface, driving style etc. This method of determining the wear of rubber is widespread, but it is not the best because of the uncertainty of the outcome.
2
Pay attention to the wear indicators – TWI (Tread Wear Indicator). They are installed by manufacturers of many brands of tires. Usually the indicators are a narrow strip between the tread blocks. For its detection should carefully inspect the sidewall. Try to see either the brand name of the manufacturer, or the arrow, or letter. If the indicator is in contact with the road (seen right), replace the tire.
3
Explore the depth of the profile. Experienced drivers determine the rate at eyes, the other with a ruler. The critical tread depth is considered to be 1.6 mm for summer tyres and 4mm for winter. Better not to bring the tires up to these minimum marks, since they already almost do not provide adhesion with the road. You are wise to change the tires earlier.

Stock up on foreign and domestic coins. Cheerful and resourceful motorists are used to determine the tire wear American 1-dollar coin, which depicts George Washington. Follow their example: in the groove of the tread, insert a coin to the top of the head of the President facing down. If the hair ends Washington's visible, it's time to change tires, if not visible, the tires will serve you.

If you had only a penny with a picture of Lincoln, and be content with them. If inserted in the groove of the tread of the coin the head of Lincoln is visible, then most likely it is time to change the tires on new.

In your pocket is ringing only domestic change? It doesn't matter. Take the 2-ruble coin, and do it with the procedure described above. The eagle head must be at the bottom. If the top of the proud bird is seen on the surface of the tread, the tire still will serve you. But if it is at least partially immersed in the groove, your tires should be replaced.

Despite the apparent futility of this method, it accurately shows the degree of tire wear. By resorting to this method many motorists.
Is the advice useful?
Check the tires for wear at least once during the month. After all, the eternal rubber has not yet been invented, and expose themselves and their passengers risk not worth it.
Note
To change tyres it is necessary not only when they wear from the time the rubber ages, causing worse sticks to the road, it cracks and deformation. In this case, replacement of tyres: continued operation may be unsafe.
