COATED WHEEL WEIGHTS NOW AVAILABLE FROM GMSPO. THE 1990-91 MODEL YEARS HAVE ALSO BEEN ADDED. ALL COPIES
OF 89-65-3E SHOULD BE DISCARDED.
Vehicles with cast aluminum wheels use a coated clip on wheel weight. The coating has recently changed from nylon to polyester, giving a more natural
appearance that more closely matches the wheel. Coated balance weights are used on both the inboard and outboard rim flanges. They will not discolor,
corrode or damage the appearance of the wheel as may have been the case in the past with uncoated clip on weights. These coated weights will fit most
GM cast aluminum wheels.
There are two types of coated wheel weights available to fit the GM vehicles (see illustration). Both types of weights are available from GMSPO in 1/4
ounce increments. See usage chart below to determine which type weight is correct for the vehicle.
