A Guide to Interpreting Car Tire Labels

Decoding Your Car's Tire Label

Selecting the correct tire is vital for optimal vehicle performance, safety, and comfortable driving experience. To do so, understanding the tire label on each vehicle is crucial.

Example tire label: P195/60R16 63H M+S

The characters and numbers indicate specific tire details. The initial four characters reveal the tire's size and type. The letter "P" signifies a passenger tire manufactured according to North American standards.

Deciphering Car Tire Labels
Absence of the "P" suggests the tire may be engineered to European ETRTO standards. The label may also include "LT," which indicates suitability for trucks or SUVs, designed for heavier loads. The letter "T" usually represents a temporary or spare tire.

The number 195 specifies the tire width in millimeters, while 60 represents the aspect ratio, which is the tire's height compared to its width, here meaning the sidewall height is 60% of the width.

The letter "R" indicates radial construction, which is the most common type, and the number 16 refers to the wheel diameter in inches. The load index 63 shows the maximum load capacity. Speed ratings such as "T" (118mph), "H" (130mph), and "S" (112mph) guide the tire’s speed capabilities. The "M+S" marking indicates all-season suitability.

Understanding these elements ensures appropriate tire selection, maintaining vehicle stability and safety. Mismatched tires can affect handling and overall performance.
