Having your tires properly inflated is essential for a safe and comfortable driving experience. Here you will learn the basics of tire pressure that will help you understand the importance of correct tire inflation.
Car tire pressure is affected by many factors, from tire specifications to outside temperature and your driving style, so it is necessary to understand these factors to maintain properly inflated tires at all times. Checking your tire pressure regularly and adjusting it to recommended levels will result in optimal tire performance, fuel efficiency and road safety.
Our resources will help you find the recommended tire pressure for your vehicle as set by vehicle manufacturer, and to check the maximum tire inflation and load capacity of your tire model and tire size.
Explore our tire pressure guide for articles, tips, answers and suggestions on how to keep the tires properly inflated for a safe and comfortable driving. Use our tire pressure calculators to calculate gas savings, convert pressure units, get proper winter tire pressure and proper tire inflation when installing new tires.
It is vital to maintain proper 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 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 pressure when tires are "cold" using quality tire pressure gauge. Adjust tire inflation to the recommended tire pressure settings as needed by adding or releasing air. Learn more on how to check tire pressure.
If you replace original equipment tires and switch to different tire size, make sure to follow guidelines for the application of load and inflation tables 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. Learn how to apply tire load inflation tables when replacing 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 recommend 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 keep tires properly inflated 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.
