Tire Pressure Basics
Tire Pressure Monitoring System (TPMS) / Tire Pressure Sensors
What is the recommended tire pressure for my vehicle?
Recommended tire pressure is set by the vehicle manufacturer based on its specifications and characteristics such as tire sizes, gross vehicle weight rating and maximum load-carrying capacity.
Where can I find recommended tire pressure for my vehicle?
You can find recommended tire pressure for your vehicle in the owner's manual, on a tire placard on driver's door or door jam, on inner trunk lid, in the console or on the fuel door.
How often should I check tire pressure in my tires?
Tires can lose air pressure naturally over time. Drop in outside temperature can also result in lower tire pressure. You should check tire pressure regularly, at least once a week, to keep tires properly inflated for a safety and comfort on the road.
When to properly check tire pressure?
Check tire pressure only when tires are "cold" and have not been driven on for at leats four hours. Checking tire pressure when tires are "hot" may show incorrect tire inflation levels due to heat expanding the air inside the tires.
Can I drive on low tire pressure?
It is highly discouraged to drive with low tire pressure as it not only lowers gas mileage and reduces tire life, but is also dangerous. Underinflated tires can overheat and break down at high speeds, which can cause a tire blowout.
What is proper winter tire pressure?
Your vehicle's recommended tire pressure should stay the same all year round in any weather. But as temperatures drop, your tire pressure can decrease about 1 psi for every 10 degrees Fahrenheit because the air inside the tire condenses, taking up less space when it's cold. Check tire pressure regularly in the winter and keep it at recommended levels.
Should I inflate my tires to their maximum psi?
The inflation psi indicated on the tire sidewall is the maximum air pressure the tire can hold while carrying its maximum load, and not necessarily the recommended tire pressure for your vehicle.
Should tire pressure be the same for all tires?
Tires on the same axle should have the same tire pressure, but some vehicles might have different recommended tire pressure settings for front and rear tires, especially when equipped with staggered tires.
Why is my tire pressure warning light on?
If your tire pressure monitoring system (TPMS) warning light comes on, it means one of your tires may have low air pressure. Check each tire, determine the cause of air pressure loss and add air to its recommended levels.
Why is my tire pressure warning light not going off?
If you have check all tires for correct tire inflation and your tires are not damaged but the tire pressure warning light stays on, there might be a problem with your tire pressure monitoring system or tire pressure sensors.
What causes a tire to lose pressure?
Tire can lose air pressure naturally over time. Leaking tire valve stems can slowly decrease tire pressure. Punctures in the tire tread will let air out even faster. Even running over pot holes can cause air to escape.
What is proper spare tire pressure?
Spare tire or temporary use tire (T125/80R15 for example) should typically be inflated to 60 psi.
