On car tires, we often see some letter identification, such as h and t. These letters represent the speed rating of the tire, which is the maximum speed that the tire can withstand.
So, what is the difference between the letters h and t?
First, let's understand the meaning of h and t. The h represents the maximum speed of the tire at 210 kmh, while the t stands for the maximum speed of the tire at 190 kmh. Therefore, in terms of speed class, h is higher than t.
So, why are there different speed classes?
This is mainly due to the fact that different tire materials and structures can cause them to withstand different speeds. When driving at high speeds, the centrifugal force and wind resistance of the tires will increase significantly, and if the materials and structure of the tires cannot withstand these forces, it will lead to problems such as tire deformation, increased temperature, increased wear, and even safety accidents such as punctures.
Therefore, in order to ensure the safe driving of the vehicle, different types of tires have their corresponding maximum speed limits.
In addition to the speed class, there are other letter identifiers on the tires, such as P, Q, R, S, V, etc., which represent different use scenarios and performance requirements. For example, P stands for a car tire, which is suitable for driving in cities and highways; R stands for radial tires, which have better wear resistance and stability; V stands for sports tires, which have better handling performance and stability, etc.
In short, when choosing tires, we need to choose the right tires according to our vehicle model, usage scenarios and performance requirements. At the same time, we should also pay attention to the care and maintenance of tires, and regularly check the wear and tear of tires, air pressure and temperature to ensure the safe driving of the vehicle.
The above is an introduction to the difference between H and T tires. It is hoped that through the introduction of this article, you can better understand the meaning and use scenarios of the speed grade and other letter logos of tires, so as to better choose and use the right tires for yourself.
