YOGYAKARTA - How to read the car tire code must be understood by the owner of a four-wheeled vehicle. Tires are an important component for car movement and driving convenience. There are various models or types of car tires that are distinguished based on several elements, ranging from the site width, diameter, to the tire height ratio.

Each car tire has its own code to show the specifications. Car owners need to choose the type of tire that fits their car model and driving needs. Because each type of car tire offers its advantages or advantages. So how to read the correct car tire code?

Before buying or changing tires, car owners need to understand the various codes on the tires. So the car owner must adjust the tires that will be used with his car and should not be arbitrary. This code is the difference between one tire and the other type.

For example, car tires that have a code of serial number and letter P 205/65 R 15 94 H. Here's how to read the car tire code and what it means you should know:

The first letter of the car tire code is usually in the form of 4 codes, namely P, LT, ST, and T. Although the use of this code is very common in foreign production tires, not all tire manufacturers in Indonesia have pinned this code. Each letter means the allocation of the use of a different car.

The Code P 'Passenger' means that tires are intended for passenger vehicles. The LT code Light Truck is a sign that tires are devoted to light trucks. The ST code Special Trailer means the type of tire intended for heavy vehicles. While the code T shows it is a type of spare tire.

After the letter, the car tire code will be followed by 3 points. This 3-digit writing shows the broader specifications of the tire tread in millimeters. For example, there is a tire type with a tread width of 250 mm. If the tire tread is wider, then the acceleration and grip power will be stronger. However, the selection of the tire tread width must also be adjusted to the rim width.

After writing 3 points, the code will be connected with 2 numbers that were previously separated by a lopsided line. This 2-digit code is the appointment of the ratio of the thickness of the tire wall to the tire tread width. For example, after the figure of 250, followed by a figure of 55. So the code means the thickness of the tire wall, which is 55 percent of the tire tread width of the car.

Furthermore, the writing of the tire code will be followed by letters and 2 numbers. There are two letter codes, namely R radial and B bias ply. Code R shows that tires are intended for passenger vehicles. While code B indicates use for heavy vehicles.

Writing a letter code is followed by a two-digit code that refers to the diameter of the wheels that can accommodate tires. Avoid wearing tires that are smaller or larger than the size of the wheels. Because this makes car movement not optimal and can cause potential accidents.

The last 2 number code shows information regarding load index or maximum limit of loads that can be stopped by tires. If the number in the code is getting bigger, the burden that can be borne by the tire will increase.

For example, the number 90 in the code means the maximum burden of the tire is 600 kg. If the figure is 70 then the maximum burden is 335 kg. While the figure 80 is able to support a maximum load of 450 kg.

The last code on the tires is written in the form of letters. This last letter is written showing the maximum speed limit that car tires can accept. The last letter code starts from Q, S, T, U, H, V, W, Y, and Z. Each letter has a different meaning for the speed limit capabilities received.

Letter Q shows the maximum speed that can be received is 160 km per hour. If the letter is S, the maximum speed is 180 km per hour, T 190 km per hour, U 200 km per hour, H 210 km per hour, V 240 km per hour, W 270 km per hour, Y 300 km per hour, and Z 240 km per hour

That's a review of how to read the correct car tire code so as not to make the wrong choice. Owners of four-wheeled vehicles need to choose tires that are in accordance with car models and their driving needs so they can drive comfortably and safely.
