This can lead to uneven wear or potential tire failure.

  2. Frequent Hard Braking:
    Frequent hard braking can lead to a reduction in tire pressure over time. This occurs because the brakes generate heat, which, in combination with slow speed from braking, can cause the tires to cool down rapidly. The tire pressure can drop due to the cooldown, resulting in lesser contact with the road and decreased performance. Research by Tire Rack in 2021 found that drivers who often brake hard have tires that can lose 1 PSI per month on average.

  3. High-Speed Driving:
    High-speed driving often increases the tire temperature, which can cause the tire pressure to rise. The higher the speed, the more heat is generated in the tires due to friction against the road surface. A 2020 report from the National Highway Traffic Safety Administration (NHTSA) indicated that driving at high speeds can lead to pressure levels exceeding manufacturer recommendations, which could increase the risk of blowouts.

  4. Cornering Dynamics:
    Cornering puts additional stress on tires, mainly if the vehicle’s weight shifts significantly. When a car corners, the tires on the outside of the turn bear more weight, causing increased flex and heat buildup. This can result in an increase in tire pressure. The Automotive Engineering Institute states that this can lead to about a 5 PSI increase in tire pressure during aggressive cornering.

  5. Load Distribution Changes:
    Changes in load distribution, such as carrying heavy loads or additional passengers, also impact tire pressure. Tires need higher pressure when carrying more weight to maintain their structural integrity.
