Wheel Weight Usage

WARNING: This page is about a different car, the 2003 GMC Sonoma, 2003 GMC Jimmy, 2003 Chevrolet S10 Pickup, and 2003 Chevrolet Blazer. However, it is still accessible from the selected car via links, so may be relevant.

Tire and wheel assemblies can be balanced using either the static or dynamic method.

IMPORTANT: When balancing factory aluminum wheels with clip-on wheel balance weights, be sure to use special polyester-coated weights. These coated weights reduce the potential for corrosion and damage to aluminum wheels.

These coated weights reduce the potential for corrosion and damage to aluminum wheels.

MC (1) and AW (2) series weights are approved for use on aluminum wheels.
P (3) series weights are approved for use on steel wheels only.
T (4) series coated weights are approved for use on both steel and aluminum wheels.

IMPORTANT: Use a nylon or plastic-tipped hammer when installing coated clip-on wheel balance weights to minimize the possibility of damage to the polyester coating.

The contour and style of the wheel rim flange will determine which type of clip-on wheel weight (1) should be used. The weight should follow the contour of the rim flange. The weight clip should firmly grip the rim flange.

When static balancing, locate the wheel balance weights on the inboard flange (2) if only 28 g (1 oz) or less is called for. If more than 28 g (1 oz) is called for, split the weights as equally as possible between the inboard (2) and outboard (1) flanges.

When dynamic balancing, locate the wheel balance weights on the inboard (2) and outboard (1) rim flanges at the positions specified by the wheel balancer.

IMPORTANT: When installing adhesive balance weights on flangeless wheels, do NOT install the weight on the outboard surface of the rim.

Adhesive wheel balance weights may be used on factory aluminum wheels. Perform the following procedure to install adhesive wheel balance weights.

Determine the correct areas for placement of the wheel weights on the wheel.
- When static balancing, locate the wheel balance weights along the wheel centerline (1) on the inner wheel surface if only 28 g (1 oz) or less is called for. If more than 28 g (1 oz) is called for, split the weights as equally as possible between the wheel centerline and the inboard edge of the inner wheel surface (2). 2.
- When dynamic balancing, locate the wheel balance weights along the wheel centerline and the inboard edge of the inner wheel surface (2) at the positions specified by the wheel balancer.
Ensure that there is sufficient clearance between the wheel weights and brake system components.
IMPORTANT: Do not use abrasives to clean any surface of the wheel.
Using a clean cloth or paper towel with a general purpose cleaner, thoroughly clean the designated balance weight attachment areas of any corrosion, overspray, dirt or any other foreign material.
To ensure there is no remaining residue, wipe the balance weight attachment areas again, using a clean cloth or paper towel with a mixture of half isopropyl alcohol and half water.
Dry the attachment areas with hot air until the wheel surface is warm to the touch.
Warm the adhesive backing on the wheel balance weights to room temperature.
Remove the protective covering from the adhesive backing on the back of the balance weights. DO NOT touch the adhesive surface.
Apply the wheel balance weights to the wheel, press into place with hand pressure.
Secure the wheel balance weights to the wheel with a 90 N (21 lb) force applied with a roller.
