Generally speaking, the normal use of the tire life is 4-5 years, Passenger Car Tyres after 5 years even if the tread wear is very small also better change, because the tire surface rubber will be due to the aging time, and many small cracks is the cause of one of the causes of the tire.Passenger Car Tyres For example, the aging part of the tread is from the tire edge or fetal shoulder, such as the edge of the beginning, long-term sun and rain will make rubber surface into a small circle of cracks, these cracks show that at this time the bearing capacity and quality of the tires have begun to decline, in order to reduce the risk of explosive tire
In addition to aging, tires are also natural wear. Therefore, Passenger Car Tyres the factory tires in the factory will mark the tire side wear limit, to indicate the real-time wear of this tire. For tires without wear marks we can also use calipers (or special tire tread scale) to measure, the general groove depth of less than 1.6 mm tires can not continue to use, because at this time the performance of the tires and the performance of the resistance will be significantly reduced. In addition, if a tyre has been repaired three or four times, Passenger Car Tyres we recommend that you better swap the tyre to a non-drive or rear wheel to reduce the risk of a blow-out.
Of course, the life of the car tires and normal use has a lot of relationship. First of all, we must ensure that the tire is always under normal tire pressure, Passenger Car Tyres too low or too high tire pressure will give the tire safety buried hidden dangers. Need to remind everyone is not to believe that the eyes see, because now most of the car assembly is no inner tube low-pressure meridian tires, sometimes from outside will feel a bit flat, Passenger Car Tyres but does not mean a certain loss of gas, professional tire pressure instrument is the only way to detect tire pressure. In addition, the test tire pressure must be if the cold tire state, Passenger Car Tyres if it is the thermal tire measurement to reduce the measured value of 0.3PA is accurate.
Tire positioning, that is, four-wheel positioning. From the literal meaning of the words, Passenger Car Tyres it feels as if it is related to the four wheels, in fact, car wheels, damping, steering levers and other chassis objects between the installation of a certain relative position, this relative position of the installation is called four-wheel positioning.
This relative position between the distance, angle and so on is the four-wheel positioning parameters, we are doing four-wheel positioning is around these parameters to make a fuss. By adjusting these parameters, Passenger Car Tyres the car can travel to the best possible state. Some of the four-wheel positioning parameters, including front wheel front beam, front wheel camber, rear wheel front beam, Passenger Car Tyres kingpin inclination, etc., have some parameters which are not adjustable.
Four-wheel positioning is not allowed to lead to vehicle running and tire wear, but also lead to car floating, sideslip, steering instability, suspension system parts wear abnormalities, Passenger Car Tyres serious impact on driving safety, so the owner needs to pay attention to the four-wheel positioning.
