Technical specifications of the tires are clearly printed on the tires, such as manufacturer, tire size, speed, tire load, shelf life (on a weekly basis). For example, we read P185 / 75R14 82S.

– P – Vehicle type: The first letter indicates the type of vehicle that can be used. P “Passenger”: tires for vehicles that can carry “passengers”. There are also other categories such as LT “Light Truck”: light trucks, pickup trucks; T “Temporary”: temporary replacement tire.
– 185 – Tire Width: The width of the tire is the contact surface of the tire with the road surface. The tire width is measured from one wall to the other (mm).
– 75 – The ratio between the height of the sidewall and the width of the tire: measured in terms of tire width/width ratio. In the example above, the thickness is equal to 75% of the tire width (185).
– R – The structure of the tire: The tires used on the car almost all have the radial structure corresponding to the letter R. In addition, the tires also have other words such as B, D, or E but now very rare in the market.
– 14 – Wheel diameter: Only one tire size can be used per tire. No. 14 corresponds to a 14-inch diameter mounted la-mount.
– 82S – Load and Speed Limits: If this number is less than the load and the speed of the vehicle is the cause of the tire explosion.
– No. 82 – Tolerant Tread Load: Typically, this position is between 75 and 105 equivalent to a load of 380 to 925 kg.
– S – Maximum tire speed can operate normally: Besides the load index is a letter that limits the maximum speed at which the tire can operate normally, with the letter S, the tire will have a top speed of 180 km / h.

The expiry date of car tires: On the front of the tire there is always a sequence of codes. With the last 4 digits, only the date of manufacture of that tire. For example, if the last 4 digits are 1404, this tire is shipped in the 14th week of 2004. The recommended manufacturer’s term is 6 years from the date of manufacture. A tire that is too “dotted” often blurred this sequence, although looking on the surface seems to have no problem at all. When the expiry date means that tires have lost their original features. The manufacturer anticipates this and advises that even new tires that are not used but only stored in stock but have expired are considered to have ended the life cycle.

The above is how to read the specifications of the tires of cars. If you master this information, you will be able to identify and make smarter decisions to protect your car.
