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




September 2021: HASETRI has successfully enhanced the scope of NABL accreditation in Wet Grip and Coast by Noise testing for Cl & C2 category tyres as per ECE R117 and proposed AIS 142.


HASETRI received Prof. SK Joshi Laboratory Excellence Award from Quality Council of India (QCI) during their Silver Jubilee celebration held on 6th October 2022 at New Delhi. This is the first testing laboratory in private sector in India to receive this Award.
