What impact do incorrectly inflated tires have on a vehicle?

Incorrectly inflated tires have a significant impact on a vehicle’s performance and safety, one of the primary effects being an increase in surface rolling resistance. When tires are under-inflated, they have more surface area in contact with the road, which leads to greater friction. This increased friction requires more energy for the vehicle to move, thereby increasing rolling resistance.

Higher rolling resistance does not only have implications for the vehicle's fuel efficiency (leading to poorer fuel economy) but also affects the handling and braking performance of the vehicle. Properly inflated tires ensure a safe and efficient ride, highlighting the importance of regular tire maintenance and checks.
