The tire is generally characterized on the basis of forces and moments being generated at the contact patch, which describes the friction potential of the tire in both longitudinal and lateral directions at different load conditions. The field conditions and applications under which the tires (especially commercial one) perform is diverse, which results in varied performance for the same product. To understand this there is a need to recognize the range of friction values the tire undergoes in different conditions. Though there are couple of methods and indoor test available to estimate the available friction potential, they are not only deficient in replicating the different real road scenarios but also prove difficult to reproduce different road surfaces. There is also a lack of availability and expense of out door test equipment in India.
