LOCKING WHEEL NUTS

ALL CHEVROLET DEALERS
Whenever a heavier, solid locking wheel nut is used to replace a standard nut, it should be installed nearest the valve stem, and a 1/2 ounce balance
weight should be added 180~ opposite the locking nut.
This situation will usually occur on styled wheels. For improved appearance, the balance weight should be installed on the wheel's inboard side.
When rotating tires, always re-install the locking nut nearest the tire valve stem so that it remains opposite the 1/2 ounce balance weight.
This procedure will improve the on-car wheel balance by compensating for the heavy locking wheel nut. This does not apply to the light weight,
two-piece locking nuts used on some Chevrolet models.
