Damage to the tireâÂÂs valve stem may lead to loss of air pressure, which, if unnoticed, could lead to a flat tire or on dual-wheels an overloaded tire. In extreme situations, rapid loss of tire pressure could increase the risk of a crash. Operators may identify an audible rattling noise from the stem extension rubbing against the wheel opening while driving. Visual inspection during inspection or during maintenance may reveal stabilizer is dislocated, damage to the stem extension, or the rim, and low tire pressure of the inner tire.
