Are your “tire dots” where they should be?
Tire manufacturers recommend the correct positioning of the red and yellow dots with respect to certain “landmarks” on both steel and alloy wheels. These dots can be used to mount tires for optimum initial balance and minimum ride disturbance – where the dots go depends on which dots – and which wheels you have.
First, if the tire has a red dot, the yellow dot is ignored! The red dot is then lined up with either the “low point dimple” (on steel wheels) or next to the valve stem on alloy wheels. Regardless of the type of wheel, if there is no red dot, the yellow dot is positioned next to the valve stem.
Why do the tire dots go where they do?
Simply put – the tire is a bit lighter in the area where the yellow dot is located, and a bit thicker where the red dot is located. On an alloy wheel, the valve stem marks the heavy point of the wheel. By matching the light point of the tire with the heavy point of the wheel it’s likely to give the best initial balance.
On a steel wheel the low point dimple marks the thinner part of the wheel – so it makes sense to match the red dot to the wheel dimple.
Abiding by these guidelines results in a precise – uniform placing and usage of wheel weights when balancing your vehicle’s tires.
