Finite element analysis is used to predict radial force variations caused by geometry and material imperfections in the tire. Imperfections, such as a change in tread compound modulus or an increase in product thickness, are applied in a 180° section of the tire model. The radial load variation for a given deflection is then computed. Experimental studies are carried out to confirm the numerical results.

Further studies investigate the influence of the inflation pressure and address the application of results to other tire designs.
