1、Is it necessary to look at the date of manufacture when purchasing tyre? In fact, the date of manufacture of tyre is not that important. For retreaded tyre, it is not difficult to tamper with this information. Regular tyre brand authorized stores sell brand-new tyre within the warranty period. Consumers don’t need to look at the date of manufacture to choose the so-called “fresh tyre”; while buying tyre online, if you don’t pay attention to distinguishing, it’s easy buying retreaded tyre processed from stock tyre or even old tyre. Even looking at the date of manufacture cannot avoid being deceived. 2、Use mileage to decide whether to replace? We often hear a saying that this XXX tyre can run at least X million kilometers. How long does it take for a tyre to be replaced? Is it really determined by the mileage used? This is actually a very imprecise point of view, after all, the environment, frequency of use and driving habits of drivers are different for each car. Therefore, we cannot use the mileage as the criterion for judging whether the tyre should be replaced. 3、What standard determines the service life of tyre? It is measured by two standards: one is the depth of the pattern, and the other is the service life. There will be a small rubber bump at every interval in the tyre tread groove. This bump is called the wear indicator point, and its height is 1.6mm. Another is the age of the tyre. The technical personnel of the tyre manufacturer suggest that the service life of the tyre should not exceed three years from the date when the tyre is installed on the vehicle. 4、 Tyre adjustment is four tyres crossed? Many people think that the positions of the four tyres are crossed, that is, the left front and the right rear, and the right front and the left rear, but this is not correct. The following principles should be followed when changing the position of the tyre: the driving wheel is changed vertically, such as left front to left rear; the non-driven wheel is changed diagonally, such as right rear to left front. The same principle applies to rear-wheel drive vehicles. If it is a four-wheel drive model or a single-guided tyre, it is directly changed vertically front and rear, such as left front to left rear, right front to right rear. The cycle of tyre exchange is recommended to be 8,000 to 10,000 kilometers. 5、Can’t use tyre with two patterns? Can’t use tyre with two patterns? When changing tyre for a vehicle, it is not necessary to change all four tyres at the same time. Tires can be replaced coaxially. For example, if you replace the front axle tyres at the same time, you only need to use tyres of the same brand and the same pattern on the same axis. The owner of the car should remember not to replace only the tyres on the same side of the vehicle, such as changing the left front and left rear at the same time. If the tyre patterns on both sides are different, it will bring hidden dangers to driving safety.
