How to Read Tire Size Code And Code Of Cars

Adults is becoming increasingly complicated, some car owners do not even understand the specifications carefully tires he used. The following will discuss the specifications of a car tire, type, code, maximum load and tire modifications appropriate for the type of vehicle. 

Car tires are generally classified into 3 types namely bias tires, radial tires and tire without a tube. 

The difference in bias tires and radial tires on the belt and the breaker is used in the inner lining of rubber tires, bias tires used breaker belt and made ​​yarn / textile whereas the radial tires and a belt made ​​from wire breaker used, these differences greatly affect the ability of collision damping on radial tires which have the ability to absorb impact better than bias tires. Tires without a tube or tubeless tire is a tire that does not require the tire, the tire is the most complicated construction. 

Seeing Triangle TWI on Tires

in the manufacture of tires 

Indicator / TWI code triangle on the tire is the tire minimum thickness limit, so if the tires have been used and thinned until it reaches the TWI these tires should be replaced immediately, delay replacement tires in these conditions will result in a fatal case such as tires burst and leak. 

How to Reading Year of Tire Manufacturing

Year of manufacture of car tires is an important thing to consider when we choose car tires, car tires that are too long in the store will decrease the quality of the tire where the rubber elasticity is reduced, cracks occurred on rubber tires, and the tires are the worst off or not functioning normally . Some due to bad tires that are too long / old is not able to adhere to the road where a normal tire, not the tire can carry the load as normal, not able to be driven at the maximum speed of the tire. The use of tires that are too old can make the car a less than ideal and the worst can result in injury to the user. 

Manufacture of automobile tires can be seen from the manufacturing code, this code contains a 4 digit number, for example in the image above (with triangle located under TWI). The first two-digit code in the manufacture of automobile tires in the picture above shows a week to 42 tires This car is made while the last two digits indicate the year in which the image above for code 10 is the year 2010 so it can be recognized that the above car tires made ​​in november of 2010. 

Car tires have a maximum carrying load capacity in kilograms that car owners should pay attention to the limits of tire load-carrying capability, over-capacity will lead to something beyond the desire for example rupture or leak. Load-carrying ability of this can be seen in the code stamped on the side of the tire, the following code load index tires 

Measuring Maximum Speed ​​Tire 

The above code, please note, if you have a car with more than 1500 Kg west with 7 passengers try to use the code 90 tires up or 90-100, would prefer the safety of passengers. 

Car tires also have a speed limit, some specific tire not allow the tire to be driven at high speeds it is dependent on the quality of the tires and car tires designs, some code to measure the maximum speed of the tire is the letter code that is started from G to Y, along with the following code maximum speed 

The speed limit should really be considered, if often drive a car in a high speed above 120 km / h should wear tires with speed code LMN and so on 

In addition to the above code there are some tires that limit the use of tires for certain cars, such as special tires for passenger car, truck and car tires for backup, the following code for a 

certain kind of car tires 

P: Passenger Car or for Passenger Cars 

LT: Light Truck or Truck Light 

ST: Special trailer or for Special Trailer 

T: Temporary or tires just for the spare tire only 

Tire Code Reading 

For example, read the tire code, we present the tire code 215 / 65R15 89H 

Analysis code 215 / 65R15 89H is as below: 

* Numerical 215 is the tread width, the unit millimeters. Numerical 65 is the aspect ratio (the ratio of the thickness profile tires with tread width). Figures 65 expressed high / thick tires that is 65 percent of tread width. 

* R is a radial tire code. If the code is entered B then tires bias tires 

* Numeric 15 shows diameter wheels (inches) 

* Numerical index of 89 indicates the load / maximum load that is 580 kilograms (code load index can be seen above) 

* The letter H after the number 89 is the code speed tire, this tire is the maximum speed of 210 Km / Hr (for code speed can be seen above) 

Below we also present a picture / schema on read code motorcycle tires that are the same with the above article 

that is not less important than the review above, that we should always care about the condition of our cars, including tires, has spare tire would be better if something unexpected happens, always keep the air pressure / tire also reduces the risk of damage to the tire, the tire is deflated too often makes us not survived the trip, so in addition to technical calculations are other factors such as driving habits we who determine our journey.
