A testing assembly calculates stress levels along a cross section of a pneumatic tire having tire beads, sidewalls, and the tread. The testing assembly includes a base defining a base surface. A plurality of mounts are slidably secured to the base surface. Each of the tire beads are secured to each of the plurality of mounts. The tire beads are mounted thereto in a manner to simulate the mounting of a tire to a rim of a wheel. The testing assembly also includes a platform that extends parallel to the base surface. The platform is engagable with the tread of the tire and is movable with respect to the base. The movement of the platform simulates the tire under a load by deforming the tire. The method for using the testing assembly includes taking measurements of the cross section of the tire in an un-deflected state. Once taken, the platform is slid to render the cross section of the tire deflected. Once measurements are again taken, the two sets of measurements can be used to calculate the stress levels of the tire along the cross section. By knowing this, the tire can be modified to minimize higher stress areas to prevent failure at these locations.
