When you drive, your tires get warmer, causing the air pressure within them to increase. Your tires can get warm after just 1 mile of driving. you should always check your tire inflation pressure when your tires are cold, and inflate them to the recommended pressure at that time.
Owner's manuals usually recommend to check the tires' air pressure weekly.
Its your low tire pressure gauge. Check all your tires and the spare as well
check the side of tires. most tires are different!
Check the air pressure in the tires.
when they are cold....
It means at least one of your tires pressure is too deflated. Check the pressure and inflat the tires to the correct pressure and rest the light.
Cold tires is just a term used to describe a tire that has not been driven lately. Driving the car creates heat in the tire thus increasing the air pressure. That is why you should always check the air pressure when the tire is cold or has not been driven for a few hours.
The correct tire pressure depends on the tire. The max pressure will be listed on the sidewall of the tire. I usually run about 5lbs less than the max. Always check your tire pressure when the tires are cold.
Check the air pressure in all tires and adjust it to the recommended PSI.
When air cools, it becomes denser and actually shrinks. If you check the tire pressure when cold and tire pressure when hot, you'll see that the tire pressure is higher when the tires are warm. Your tires were probably borderline low before the temperature changed. To minimize the effect, you can fill your tires with nitrogen instead. The pressure will fluctuate less. Check the pressure in your tires every time you fill up. You'll get better gas mileage, and your tires will last longer if you maintain the correct pressure in them.
Check the sidewalls on the tires. It will be "printed" there.
