Research has consistently shown that optimal psi levels can lead to significant improvements in fuel economy, with estimates suggesting a 3-5% reduction in consumption for every 1 psi increase. This is because proper psi helps to reduce rolling resistance, which in turn enables the tire to move more efficiently.
The Science Behind Psi and Fuel Efficiency
To grasp the intricacies of psi and fuel efficiency, let’s delve into the underlying physics. When a tire is inflated to the optimal psi, it creates a more robust contact patch between the tire and the road surface. This results in a lower rolling resistance coefficient (RRc), which measures the energy lost as the tire rolls. The relationship between psi and RRc can be approximated by the following formula:
RRc = (psi x diameter) / (tire load x radius)
By manipulating this equation, we can see that a higher psi will lead to a lower RRc, provided the other variables remain constant.
