The Summer Factor: Temperature. Temperature also affects density altitude. When you heat the air, the air molecules have more energy. And, when they have more energy, they spread farther apart. (You probably learned this in high school chemistry class...). When the air is warmer than standard, it's less dense and performance decreases.
Drivers need to be aware that tires lose small amounts of air pressure each day through a process called permeation. Some factors that contribute to air pressure loss are as follows: Cooler temperatures can cause the air in your vehicleâs tire to contract (roughly 1-2 psi of air a month). Seasonal, or altitude changes, can cause a drop in air pressure (for every 10 degrees change in temperature, tire air pressure changes 1psi).
