Which property does the letter V in a tyre marking express?

  • A.The temperature grade, which indicates the ability of the tyre to dissipate the heat generated during running
  • B.The maximum speed for which the tyre is approved
  • C.The construction of the tyre, indicating that it is of radial type with a steel belt beneath the tread
  • D.The load index

Answer: B

The speed symbol V corresponds to 240 kilometres per hour, and H to 210. Radial construction is shown by the letter R within the size. Temperature grade is a separate marking in the American system. Reading the definition literally, rather than recalling a summary, avoids the usual confusion. Naming what changes and what stays the same is the reliable route through questions of this shape. The order in which the effects act is what decides the outcome, so it is worth establishing first.
