TKPH Calculator

    TKPH stands for Tonne-Kilometres Per Hour (or TMPH: Ton-Miles Per Hour), and is a rating for each tyre specification representing load carrying capacity in relation to heat generation. This rating is compared to site TKPH, which represents the operational TKPH of any given vehicle.

    Tyre selection is one of the most important factors for tyre life. Choosing the correct tyre specification with the most appropriate TKPH rating for site operations can significantly improve tyre life and reduce vehicle operational costs.
