V: This indicates speed rating i.e. an alphabet code corresponding to max tyre speed in km/h rated under conditions specified by tyre manufacturer. Speed rating table contains a list of speed rating and their corresponding max tyre speed. For example, a speed rating of V corresponds to max tyre speed of 240km/h.

AUTOMOTIVE SYSTEMS – TYRE PRESSURE

WHAT? Tyre pressure is the amount of air pressure in the tyre. The recommended tyre pressure for your vehicle is typically printed on the vehicle door placard or in the vehicle owner's manual. Do not use the tyre pressure displayed on tyre sidewall as this represents maximum allowable pressure for that specific tyre.

WHY? Proper tyre inflation pressure ensures safe driving and improves tyre life and fuel consumption by reducing uneven or premature wear.

WHEN? Tyre manufacturers usually recommend to check tyre pressure (including spare tyre) at least monthly, before long trips or travelling with heavy loads.

AUTOMOTIVE SYSTEMS – TYRE BALANCING

WHAT? Tyre balancing is the process of compensating for the weight of tyre and wheel after assembly using balance correction weights.

WHY? Proper tyre balancing ensures safe driving and improves tyre life by reducing premature wear. Proper balancing also prevents unnecessary wear to vehicle suspension.

WHEN? Tyre manufacturers usually recommend to check tyre balance:

· when one area is heavier or lighter than the rest

· vibrations, bouncing or wobbling occurs

· before new tyres are installed

AUTOMOTIVE SYSTEMS – TYRE ROTATION
