Q:The left rear tire side of the car scratch, need to change it?

From the line of tyre usage, there will be four digits on the side wall of the tire indicating the date of manufacture of the tire, the first two representing weeks, and the last two representing the year. The use of tires generally do not exceed 3 years, mileage is not more than 60 thousand kilometers. Although slightly longer than the length of life and mileage is no harm to the overall situation, but the winter low temperature and summer rain will make the tire of wetland grip and dry ground handling is relatively poor.2, pay close attention to the side wall of the car tire: as the tire rubber gradually aging, the tire side wall will appear deep lines. However, as long as the sidewall of the tire is not impacted and the cord is not broken, it can continue to be used. The triangle mark on the side wall of the tire can help the owner find a protuberance in the groove of the crown, and can determine the actual wear limit of the tire. The value should be greater than 1.6 millimeters.

Q:Automobile tire exchange principle

If the tyres are properly transposed, they will make the tires more uniform, extend the service life of the tires and provide better handling performance throughout the life cycle of the tires.

Q:Does anyone know what brand of big truck is used in the market now?

Generally used drivers will be more understanding, because HANKOOK tires longer life, more wear-resistant, performance is relatively stable, the most important is cost-effective.

Q:A gas car tires have not stopped for a night, I'll crush the tires, what's the problem

It depends on the specific circumstances!If the tire can fix it, it is best to fill the front wheel, tire suggestions play a tyre dynamic balance!

If only minor deformation, you can continue to use.Attention: the balance of the tires is always about two hits, do not hit only one side!

Q:How often do the tires change?

A car tire 2.5 in winter, 2.2 in summer, the highest pressure tire can withstand the tire side, reasonable pressure of tire mark maximum pressure of 70%-80%, but it is best not to pressure higher than the maximum pressure of tire mark.
