What happens when tire pressure is too low (under-inflated)?

Explanation:
Under-inflated tires deform more as they roll, so the tire doesn’t keep a stable, even contact with the road. This makes steering feel slower and less precise, and grip can suffer, especially during cornering or braking. At the same time, the tire works harder due to increased rolling resistance from the extra flex, which wastes energy and lowers fuel efficiency. The extra heat and unequal wear from the deformation also raise the risk of tire damage over time. So, under-inflation harms handling and reduces fuel efficiency.
