Does tire pressure really drop in hot weather?

No, tire pressure does not drop in hot weather. In fact, it typically increases due to the expansion of air inside the tires.

As the temperature rises, the air within the tires heats up and expands. This expansion causes an increase in tire pressure. Conversely, if the tires are used in cooler temperatures after being heated, the air will contract, potentially leading to decreased tire pressure. Properly monitoring tire pressure is essential for vehicle safety and efficiency. Always check tire pressure when the tires are cold for the most accurate reading.

How does the temperature impact tire pressure?

Temperature impacts tire pressure significantly. As temperature increases, tire pressure rises. This happens because air expands when heated. Conversely, when temperatures drop, tire pressure decreases since air contracts. For every 10 degrees Fahrenheit change in temperature, tire pressure changes by about 1 psi (pound per square inch). This means that in hot weather, under-inflation may lead to poor handling and increased tire wear. In contrast, cold weather can result in over-inflated tires that may affect traction and ride comfort. Therefore, it is essential to regularly check tire pressure, especially during temperature fluctuations, to ensure safety and optimal vehicle performance. Adjusting tire pressure according to temperature changes helps maintain ideal contact with the road. Proper inflation also enhances fuel efficiency and prolongs tire life.
