Optimal inflation for tires is influenced by ambient temperature. As temperatures rise, the air inside tires expands, increasing the pressure. Conversely, cooler temperatures cause air to contract, leading to lower pressure readings. For instance, a tire inflated to 35 psi on a 70F day could read close to 38 psi on a 90F day.
Maintaining correct inflation is crucial for vehicle safety, performance, and fuel efficiency. Properly inflated tires ensure optimal contact with the road surface, improving handling, braking, and traction. This also minimizes the risk of blowouts, reduces uneven tire wear, and optimizes fuel economy. Historically, understanding the impact of temperature on tire pressure has become increasingly important with advancements in tire technology and greater emphasis on fuel efficiency.
