Low or high tire pressure can severely impact vehicle safety during rainy weather. Here is a detailed explanation of the dangers associated with both conditions.
-
Loss of Traction:
Low or high tire pressure affects the contact area between tires and the road. Loss of traction occurs when tires cannot grip the wet surface adequately. Under-inflated tires expand, causing excessive surface area that can lead to slippery handling. Over-inflated tires create a narrower contact patch, increasing susceptibility to slip. According to a 2021 study by the National Highway Traffic Safety Administration (NHTSA), improper tire pressure significantly increases the likelihood of loss of control in wet conditions. -
Increased Hydroplaning Risk:
Increased hydroplaning risk arises from both low and high tire pressure. Hydroplaning occurs when a layer of water builds between the tires and the road, causing the vehicle to slide uncontrollably. At low tire pressure, tires cannot channel water effectively away from the contact surface due to decreased rigidity. Conversely, over-inflated tires have less tread surface in contact with water, leading to a higher chance of losing grip. The NHTSA estimates that hydroplaning is a contributing factor in over 16% of vehicle crashes during rainy weather. -
Reduced Braking Efficiency:
Reduced braking efficiency is a critical danger of tire pressure irregularities. Low tire pressure results in softer tire walls, increasing stopping distance. In contrast, high tire pressure may lead to harsh ride conditions and less surface area for effective braking.

Tire Blowouts:
Tire blowouts can occur when tires are operated under extreme conditions of low or high pressure. Low pressure can lead to overheating due to excessive flexing of the tire sidewalls. High pressure increases the likelihood of tire damage from road imperfections, causing explosive failures. The Tire Industry Association reported that up to 90% of blowouts are attributed to improperly inflated tires, highlighting the need for regular pressure checks. -
Increased Wear on Tires:
Increased wear on tires is a consequence of improper tire pressure. Low pressure causes uneven tread wear and sidewall flexing, leading to premature tire aging. High pressure may lead to center wear, reducing the tire’s lifespan. The American Automobile Association (AAA) emphasizes the importance of maintaining correct tire pressure not only for safety but also for financial reasons, noting that properly inflated tires can extend tire life by over 25%.
