Ordinary people can't imagine the power of a truck with a flat tire. The standard tire pressure of a car with an average dead weight of about two tons is 2.5 atmospheres. Generally, the tire pressure of large trucks should reach 7 to 10 atmospheres, and some even exceed 10 atmospheres. If the tire of a heavy truck explodes, the power is equivalent to a grenade.
In order to avoid tragedy, it is necessary to pay attention to the use of tyres. How often is it appropriate to change the tire? It is well known that the warranty period of tyres is generally 6-100000 km or 3-5 years, but after more than 60000 km, their wear has reached a certain degree. The more frequent use, the greater the possibility of problems, so it is recommended to replace them early.
A wear mark is set at the bottom of the tread groove of all tires. Generally, the wear mark height of car tires is 1.6mm, and that of truck tires is 2.4mm. If the tread pattern of the tire is worn flush with this mark, it means it needs to be replaced. Wait until all the tread patterns have been worn, and then replace them.
In addition, if the tire is bulging, it proves that the metal coil inside the tire has been deformed or broken. If you continue to drive, it is very likely to cause a tire burst, and you must replace it immediately!
