Hot wheels tires

Tire pressure is an issue that car owners should always pay attention to, but some car owners may think that they are buying tires from big brands, such as Michelin, Goodyear, Bridgestone, Dunlop and other international brands of tires, so the quality can be guaranteed.Even if the tires are out of gas, it should be fine to drive as usual.And this idea is wrong, and there are countless accidents caused by lack of air. 1.When the tire pressure is lower than the normal value, the tire will soften, and the deformation will increase. Once the contact area between the tire and the road surface increases, the friction coefficient will increase exponentially, causing the tire temperature to rise sharply. In this case, if the car is still driving at high speed, the heat will quickly gather together, and the inside of the tire will begin to separate and delaminate, causing the tire to burst.If the car is driving at low speed, the tire will be injured due to excessive tire deformation.The latter situation is more dangerous due to the long incubation period and high concealment. It lays a hidden danger for the tire to burst when driving on the highway in the future. 2.Due to the excessive deformation of the carcass caused by the lack of air in the tire, it is prone to cord fracture or even faults, which can cause the tire zipper tire to burst in severe cases. “Air pressure is the life of the tire, and high temperature is the main killer of the tire”" This sentence is not excessive at all.If the tire pressure is 20 percent lower than the normal value, the life of the tire will be reduced by 30 percent, reaching a critical point that endangers safe driving.Therefore, in addition to doing a good job of tire maintenance, drivers should also pay attention to checking the tire pressure, keeping the tires under standard air pressure, and ensuring driving safety.

Sports car tires are thinner because they can have a stronger grip. When the power output of the vehicle increases, the grip also needs to increase, otherwise it is difficult to cope with the output torque.If you want the grip of the tire to become stronger, you can widen the tire, but this will increase the fuel consumption of the vehicle. Sports car tires generally do not use a way to widen the tires to enhance grip. It is to make the diameter of the rims larger and the length of the rim banners longer, so that the rubber raw materials needed on the tires will become less, the thickness of the tires will become thinner, and the engine power will have more room for improvement, so that the speed of the vehicle can be increased. Sports car tires are relatively thin and are not suitable for household vehicles. Household vehicles are more pursuing quiet and comfortable performance, but if the tires are relatively thin, there will be greater tire noise when driving, and the ride comfort will be greatly reduced.Thin tires are generally suitable for vehicles with strong sports performance, so that the handling provided will be more stable, and when driving at high speed, it will have relatively good performance. Thin tires and low flatness have the same meaning. The lower the flatness of the tire, the stronger the handling. If the flatness of the tire is relatively low, then its sidewall will be relatively solid. When the vehicle is turning, the tire is not easy to deform. Tires with low flatness will have a greatly reduced shock absorption effect, so that comfort will plummet, so sports cars will have a loud roar when driving, and the overall performance on slippery roads is relatively poor. When driving a sports car on rainy days, pay extra attention to safety.
