I have a 2007 Yukon Denali and I have been hearing I need to keep the tire pressure at 40 psi front and rear at all times. Can you please tell how much psi it should be in cold and hot weather?

    Your hot and cold weather pressure should be same as recommended by vehicle manufacturer. Your tire pressure will fluctuate with atmospheric temperature changes - when temperature goes up, so does your tire pressure, when temperature drops, tire pressure drops too. You have to maintain recommended tire pressure in your tires by adding or releasing some pressure as needed to keep it at 40 psi. Just make sure you measure your tire pressure when your car is "cold" meaning when it has not been driven for at least 3-4 hours, preferably first thing in the morning.
