Proper tire pressure in your vehicle's tires is essential for a safe, efficient, and comfortable drive. Here you will learn the basics of tire inflation to help you understand its importance.
Car tire pressure is affected by many factors, from tire and vehicle specifications to outside temperature and your driving style, so it is necessary to understand how to maintain correct tire inflation at all times. Checking tire pressure regularly and maintaining correct tire inflation will maximize the life of your tires, provide smooth and predictable handling, improve gas mileage, and keep you save on the road.
Our resources will help you find recommended tire pressure settings for your vehicle set by the manufacturer, and to check the maximum tire inflation and tire load capacity of your tire model and tire size.
Explore the tire pressure guide for useful articles, tips, answers and suggestions on how to maintain tires properly inflated. Use tire pressure calculators to calculate gas savings when tires are inflated correctly, convert pressure units like psi, bar and kilopascals, find recommended winter tire pressure when ambient temperatures change and correct tire inflation for replacement tires.
It is vital to maintain correct tire inflation pressures for your car, minivan, light truck, pickup, crossover or SUV tires. Low tire pressure and underinflated tires can lead to uneven and excessive tire wear, poor handling and reduced fuel economy. High tire pressure and overinflated tires can result in reduced traction, poor braking and can even be a cause of a tire blowout. Check tire pressure regularly and maintain correct tire inflation for your vehicle to enjoy a safe and comfortable drive.
Recommended tire inflation pressure for your vehicle is determined by the manufacturer based on its characteristics and original equipment tire sizes. You can find recommended tire pressure in vehicle owner's manual or on a tire placard on the side of driver's door or door jam. Tire inflation will be listed in psi (pounds per square inch), bar or kPa (kilopascals). Keep in mind that tire inflation listed on tire sidewall is the maximum air pressure the tire can hold to carry its maximum load, and not necessarily the recommended tire pressure for your vehicle. Your vehicle may also have different recommended tire pressure settings for front and rear tires, especially if equipped with staggered tires.
To check tire pressure for your car, minivan, light truck, pickup, crossover or sport utility vehicle you will need to know its recommended tire inflation and a tire pressure gauge. Check tire inflation when tires are "cold" and have not been driven for at least 3 hours. Adjust tire inflation to the recommended tire pressure levels as needed by adding air with a tire inflator. Learn more on how to check tire pressure.
If you replace original equipment tires with optional or plus tire sizes, make sure to follow guidelines on how to apply tire load inflation tables when replacing tires to find proper tire pressure for new tires on your vehicle. Always refer to the vehicle owner’s manual for any specific safety advice regarding the application of replacement tires.
Tire pressure fluctuates with ambient temperatures, so during winter when temperatures drop tires may lose approximately 1 psi of air pressure for every 10 degree Fahrenheit decrease in temperature. Some vehicle manufacturers may suggest inflating tires 3 to 5 psi above the recommended tire pressure settings to compensate for lower temperatures during winter. Make sure to check tire pressure more often in the winter to maintain correct tire pressure for a safe ride on snow and icy roads. Learn more about recommended winter tire pressure.
If your vehicle is made after 2007, it should be equipped with tire pressure monitoring system that uses tire pressure sensors to alert the driver when tire pressure is low. If low tire pressure warning light is on, check all tires for low air pressure and inflate as needed. If you need to reset tire pressure monitoring system, refer to owner's manual on how to reset TPMS for your vehicle.
