What is the primary effect of low tire pressure on vehicle performance?

The primary effect of low tire pressure on vehicle performance is increased heat generation. When tires are not inflated to the recommended pressure, they tend to deform more as they roll, resulting in extra flexing of the sidewalls. This flexing generates additional heat due to the increased friction between the tire and the road surface as well as within the tire itself. Over time, this excess heat can lead to tire wear, reduced traction, and even tire blowouts if not addressed. Maintaining the correct tire pressure is crucial for safety and overall vehicle efficiency, as it helps ensure optimal handling and performance while also promoting better fuel economy and tire longevity.
