Stiffness Test

Stiffness or spring rate tests are used to determine the resistance of tire to deflection or deformation by the applied force.

HASETRI houses test machine capable of measuring the stiffness of the tire along 3 coordinate axes & 1 angular axis: radial(z), lateral (y), longitudinal (x), and torsional stiffness respectively. The facility for performing stiffness tests is available for the following tire categories.

Passenger car tire/ Light truck (C1/C2)
Truck/Bus tires (C3)
Motorcycle tires (Two and three-wheeler tyres)

The test machine can perform the stiffness test in compliance with the following test standards.

AIS 044
SAE J2704
SAE J2718
