Force and Moment

    Smithers can provide force and moment data for passenger, light truck and racing tires over operating ranges from parking lot speeds to the limit of the V speed rating. Tires can be testing at loads up to 5,500 lbs (25 k-N) as a function of the load, slip angle, inclination angle, speed and driving/braking torque.

    Tires which range in size from small aircraft to passenger car and heavy truck can be tested at loads up to 10,000 lb (45 k-N) as a function of load, slip angle, inclination angle and speed. Available data include:

    • Stresses and motions in the tire footprint
    • Tire forces and moments
    • Lateral, longitudinal and vertical spring rates
    • Custom items, such as force development with distance rolled, bead/rim pressures, etc.
