  • A properly mounted and inflated tire on a recommended rim or wheel and running at
    rated load, seldom permits the area above the bead heel to contact the rim flange,
    except during severe handling maneuvers. However, during conditions of overload
    and/or underinflation, or brief periods of high cornering, cambering, braking, or
    driving torque, the rim flange radius is pressed against the lower sidewall with
    considerable pressure. Over-deflection permits the area above the bead heel to contact
    the rim flange, creating a condition on the tire that is often described by tire engineers
    as compression grooving. Compression grooving is the permanent circumferential
    indentation of the rubber at the interface of the rim flange radius and the upper
    bead/lower sidewall area of the tire. The overdeflection also contributes to abrasion of
    the surface of the rim flange radius.
    This paper will discuss the occurrence of compression grooves and rim flange abrasion
    as indicators of tire abuse. The presentation summarizes the results of scientific
    studies designed to compare proper operating conditions to a variety of over-deflected
    operating conditions. as well as their relationship to tire endurance, tire-to-wheel
    fitment, and corresponding pressures in the bead area.
