When you purchase new tires, you might notice a small red or yellow dot. At first glance, these dots might appear as insignificant markings, but they actually play a vital role in your tire’s performance and longevity. Knowing what they represent can make all the difference in how well your tires perform over time.The red dot indicates the highest point of radial force variation on the tire, marking its stiffest or heaviest section. While tires are made to be as uniform as possible, no tire is perfectly round or perfectly balanced.
This red mark ensures that the heaviest section of the tire aligns properly with the wheel, minimizing vibrations and improving driving comfort.On the other hand, the yellow dot signifies the point of lightest weight on the tire, often indicating where the tire is most balanced. This mark helps during tire installation by guiding technicians to align this lightest spot with the valve stem on the wheel. This ensures that the wheel and tire assembly is better balanced, which can lead to smoother rides and less wear over time.
Properly aligning these dots during installation isn’t just a suggestion — it’s a key factor in maximizing tire performance. Misalignment can lead to uneven tire wear, vibration, and a decrease in overall lifespan. By ensuring that these dots are aligned with the wheel’s corresponding points, you’re setting your tires up for optimal performance.
