Have you wonder about the meaning of the letter and number mentioned on your car’s tyres side. Let’s check. The Side of tyres have Brand name and model name. Apart from this it also have mysterious code of letter and numbers. This code represent all the information related to tyre specification.
Most of the tyre has something similar code random For
example, P205/65 R16 95V
The first letter of the code indicate that this tyre is made
for particular type of vehicle. In above case P stand for Passenger vehicle. Some
of other example of first letter i.e. T stand for Truck, LT means Light Truck
Vehicle, C stand for Commercial etc.
The three digits before the slash indicate the tyre width in
millimetre. All tyre of the Car must have the same tye width.
Two numbers after the slash denotes the aspect ratio
expressed in percentage. It compare the tyre height with tyre width. If you
have to change one tyre then ensure the aspect ratio will be same as other
tyre. For example if two number after slash are 65, it means tyer height is 65%
of the tyre width.
After aspect ratio a single letter represents how tyre was
constructed. In above example R indicate the radially construction. After this
letter there is two digit number which denotes the rim diameter of the wheel. In
above example two digits are 16, means Rim size is 16 inches.
Last two digit and letter combination indicate the load index and max speed capability. In above instance V stand for max speed of 240 kmph as per speed rating. Few of other letter i.e M for max speed 130 kmph, P for max speed 150 kmph, R for max speed 170 kmph.
