  • The beginning 3 numbers signify the cross-section width of the tyre in millimetres. Thus it is 195 mm in this case.

 

  • The next value is the aspect ratio which is the value of the height of the tyre sidewall expressed in percentage of the width of the tyre. Thus, in this case, 55 depicts that the height of the tyre is 55% to the width of the tyre which is 195 mm.

 

  • The next alphabet signifies the way the tyre has been constructed. There are 3 ways in which tyres are manufactured. Radial, Bias-belt, and Diagonal. 

 

  • Generally, most of the tyres are manufactured in the radial form where the cord plies in the tyre are arranged at 90 degrees to the direction of the travel of the vehicle.

 

  • Next two consecutive numbers signifies the rim width. In this case, it is 16 inches.

 

  • The final set of numbers is known as the load index of the vehicle. It is the maximum load-carrying capacity of the vehicle.

 

  • Alphabet after load index is known as the speed symbol with alphabet L signifying least speed and V signifying the maximum speed of 240 km/h
