Once you have done with the research of appropriate tyre size then go and purchase a new set. In case of any further queries, go and call the manufacturer to guide you with more details.

How to read the size tyre?

As we have discussed the tyre size is written in a series with a collection of symbols, alphabets, and numbers. This series can never be readable for you if you don’t know the backend written details. Here, we are going to tell you the way to read the tyre size series with an example. 

Suppose that you have written a size code P251/52/R1215S on your snow tyres. This code is divided into various classes the P indicates the Tire Class and the next written number 251 tells us about the width of the tyre in millimeters. 

After that 52 is the aspect ratio and R indicates the tire construction. Moreover, the first two numeric digits 12 next written to R indicate the wheel diameter size in millimeters and the last two numeric digits 15 indicate the load index. Finally, the last alphabet S indicates the speed rating.

 

Details about all the codes of tyre size serial number

All the details about the code of tyre size that is mentioned in a serial number are written here. Let’s have a look;

• Tyre Class (P251/52/R1215S); 

The Tyre class is something that will help you to know which type of vehicle the tyre is built for. Commonly, there are two tyre cases present for average drivers that are P and LT. Here P indicates the Passenger’s car (cars, SUVs, light pickups, etc.) and LT indicates the Light trucks (SUVs, Pickups, and Vans). 

• Tyre Width (P251/52/R1215S); 

The number 215 indicates the width in millimeters which tells us the tyre’s contact with the road. 

• Aspect Ratio (P251/52/R1215S);

The aspect ratio of a tyre’s height to its width. 

• Tyre Construction (P251/52/R1215S)

Tyre Construction tells about the cord plies that work to straighten the tyres and shape the tyre. Radical cord piles denoted by R are the standard of today while some tyres are diagonal or bias cord piles (D). 

• Wheel Diameter Size (P251/52/R1215S) 

Wheel diameter size is also known as rim size. For Example, a tyre having 15 inches wheel size can only be fit onto a wheel having 15 inches diameter. 

• Load Index (P251/52/R1215S)

The load Index rating falls somewhere between 75 and 100. This number corresponds with the weight load that a tyre can carry. For example, if you find 19 then it means that the tyre can support 1520 lbs. 

• Speed Rating (P251/52/R1215S) 

The maximum speed of a tyre is related to its class. Ranges from the lower speed rating for the passenger tyres to the higher rating performance vehicle. The speed rating of a tyre includes 3 categories of speed ratings that include H, S, and T. 

Here H comes with 210 km/h that has 130 mph and is commonly recommended for passenger cars and sports cars. S has 180 km/h that has 112 mph and is recommended for use with sedans, minivans, and other trucks. Last is the T which has 190 km/h that has 118 mph and is good to use with sedans, minivans, and light trucks as well.

The Bottom Line

That is all about this reading and here we are going to wrap up this article. In this reading, we have discussed all about the tyre size. Some people say that not using the right tyre will not affect the performance but actually, it affects the performance, controlling, and handling of the tyre.

This reading is going to end here and we hope that you have gotten all the information and are ready to pick one according to the measurement of your vehicle’s tyre. So, why are you standing here? Pick a measurable one and make your driving smoother
