Tires are the only component that has direct contact with the road surface, playing a crucial role in ensuring safety and performance while driving. However, many drivers often neglect tire pressure, leading to potential dangers and severe consequences.
In this article, VietNamNet will reveal the hazards of driving with underinflated tires.
Risk of Accidents
Low tire pressure increases the contact surface area with the road, resulting in higher friction. This can lead to tire overheating, increasing the risk of tire blowouts or punctures if sharp objects are encountered. Such incidents are hazardous when navigating traffic.
Additionally, a single underinflated tire can disrupt the balance and stability of the vehicle, especially when driving at high speeds or navigating curves.
According to statistics from the National Highway Traffic Safety Administration (NHTSA) in the United States, underinflation is a contributing factor in approximately 11,000 traffic accidents annually.
Accelerated Tire Wear
Insufficient tire pressure causes uneven wear on the tire surface, accelerating the deterioration process. When tire pressure is inadequate, the center of the tire is pushed down, leading to rapid wear on the tire shoulders. This not only shortens the tire’s lifespan but also increases maintenance and replacement costs.

Underinflation increases rolling resistance, forcing the engine to work harder to maintain speed. Consequently, this raises the tire’s temperature and accelerates wear. Research by the Rubber Manufacturers Association (RMA) indicates that driving with underinflated tires can reduce tire life by up to 25%.
Increased Fuel Consumption
Underinflated tires create higher rolling resistance, requiring the engine to work harder. This results in increased fuel consumption, directly impacting the vehicle’s operating costs. According to a study by the US Department of Energy, underinflation can increase fuel consumption by up to 3%.
Impact on Suspension System
Insufficient tire pressure can cause significant damage to the vehicle’s engine and suspension system. When tires are underinflated, the car’s ride quality is affected, and it may experience excessive swaying on the road. This creates uneven stress on the suspension components, such as shock absorbers and springs, leading to their overwork and increased risk of failure or reduced lifespan.
General Assessment
Modern vehicles are typically equipped with a tire pressure monitoring system (TPMS). This system continuously monitors tire pressure and alerts the driver when it falls below the recommended level. For vehicles lacking this feature, aftermarket TPMS units can be purchased and installed.
The standard tire pressure information is usually printed on a sticker inside the vehicle’s door or in the owner’s manual. Checking tire pressure when the tires are “cold,” meaning the vehicle has not been driven for a significant distance or has been stationary for at least three hours, yields the most accurate results.
