## 🔴 What Do the Red and Yellow Dots on Tires Indicate?

Tire manufacturers aim to produce the most balanced and uniform tires possible. However, due to the complexities of tire construction and materials, achieving perfect symmetry is challenging. To address this, manufacturers use red and yellow dots to indicate specific points on the tire that assist in achieving optimal balance during installation.([tireagent.com][1])

### 🔴 Red Dot: Identifying the High Point of Radial Force Variation (RFV)

The red dot marks the tire’s point of maximum radial force variation. Radial force variation refers to the differences in tire stiffness as it rotates, which can cause vibrations if not properly addressed. By aligning the red dot with the wheel’s low point (often indicated by a dimple or sticker), technicians can minimize these vibrations, leading to a smoother ride and reduced tire wear.

### 🟡 Yellow Dot: Indicating the Lightest Point of the Tire

The yellow dot denotes the tire’s lightest point. During installation, this mark is aligned with the wheel’s heaviest point, typically the valve stem. This alignment ensures that the lightest part of the tire compensates for the heaviest part of the wheel, reducing the need for additional balancing weights and promoting a more balanced wheel assembly.
