The tire is very important for the car, no car can run multiple blocks, out of the four foot. Butsuch a key part is very vulnerable to owners of neglect, in the second-hand car purchase anddaily use, we should improve the tires of the vehicle inspection, the method of editing, as owners of six self check the tire.

1, prick holes

The car was stuck tire? If there is how long ago? In fact, for a long time already fill tires, even if temporarily with no problem, but in the ultimate load capacity is much larger than in the past; in addition, the same tyres if you have got more than 3 holes, we recommend that you replace it as soon as possible.

2, drum kit

The car at high speed through the pits, if obstacles and walls, parts of tire in the huge impact force will have serious deformation, thus the internal pressure increases, the direct consequence is caused by the side of the tire cord rupture caused by bulging. In addition under the same impact force, low aspect ratio tire tire more easily than high flat sidewall bulge. Has been inflated tires must be replaced immediately, otherwise there is a danger.

3, the pattern

Generally speaking, the normal use of the family car every 60000 kilometers or two years to change a tire tread wear, but for serious tires should be replaced. Now the repair shops havetread wear ruler, owners can buy a tread wear of tire, testing their own at any time. In addition,the tread crack is increasing serious aging symbol, usually can be sprayed some tire protectionwax, there is driving so as not to pressure to the corrosive liquid.

4, air pressure

Most cars are now using the meridian tubeless tire, the drive is due to the engine, gearbox and other important drive components are pressed on the front wheel, so sometimes you may look a little flat, but visual inspection is not accurate, must use special tire pressure gaugemeasurement. In general the front pressure between 2 and 2.2 PA (PA, the use and design of each vehicle is different, so it is best to use the numerical reference manual calibration), summer may be appropriate to lower.

5, spare tire

If you want to play a real role in emergency spare wheel, usually pay attention to themaintenance. First of all, should always check the tire pressure; secondly, to pay attention to the anti corrosion of oil spare tire, tire rubber, are most afraid of erosion of all kinds of oil. The tyreswould occur very soon after the oil, corrosion expansion, which will reduce the spare tire service life greatly. Finally, the spare life of 4 years or so, many people mistakenly think that has been the new spare not, in fact, the past 4 years even the spare tire had never once used to replacethe spare tire, otherwise a waste tire.

As the only car tire contact with the ground parts, its role is very important, for security is great.So Xiaobian remind you, in the purchase of second-hand car, in addition to the price of the car,mileage (ginseng, pictures, inquiry) and other information, the factors affect the safety tire condition must pay special attention to; at the same time, after the purchase of second-hand car,because the car itself has been used for a period of time, the tire wear to some extent, it is frequently necessary to inspect the tire and detection.
