You can improve your gas mileage by 0.6% on average—up to 3% in some cases—by keeping your tires inflated to the proper pressure. Under-inflated tires can lower gas mileage by about 0.2% for every 1 psi drop in the average pressure of all tires. Properly inflated tires are safer and last longer.
The proper tire pressure for your vehicle is usually found on a sticker in the driver's side door jamb or the glove box and in your owner's manual. Do not use the maximum pressure printed on the tire's sidewall.
Maintain proper PSI for better performance
Tire efficiency is all part of getting the maximum return on investment for anything related to your automobile. Maintaining the proper psi will allow your tires to last months or even years longer than ordinary. It also means that the miles per gallon are the best that can possibly be gotten out of your car’s fuel. It all adds up over time. Very simple inspection tires and proper inflation can save you hundreds of dollars over the life of the tires.
Studies have proven that the Fuel Use index increased dramatically while the tire pressure decreases (under-inflated). And as you can see in the graphics below, the right-hand chart reflects the very situation of how the underinflated tire can raise fuel use.
Knowing Your Exact Tire Pressure Reading
All that being said, to know your tire pressure readings all the time can really help you improve your gas mileage. For those old vehicles that aren't equipped with TPMS that have exact readings, we highly recommend our ZUS Smart Tire Safety Monitor. Equipped with the German sensors to collect real-time pressure data, the algorithm behind the scene really makes ZUS STSM the most reliable piece in the market. This AccuTemp algorithm can tell the car owner if a tire is in the trends for a slow leak by analyzing the data collected. Keep using ZUS STSM will help you grow the habit of maintaining your tire pressure within a healthy range and avoid the embarrassment of worrying about your tire pressure during your drive.
What's more, the STSM is about to support the Mileage Log and Car Finder Feature before Christmas! Check more on the details of these two features.
