Under normal driving conditions, air-filled tires may lose 1-2 PSI (pounds per square inch) per month as air permeates through the tires.
Of the 130 billion gallons of fuel used in passenger cars and light trucks in 2005, about 1-2 billion gallons were wasted as a result of driving on under-inflated tires.

About90% of tire failures were caused by under inflation. -- American Trucking Association
Properly inflated tires not only save lives, they also reduce tire wear and increase fuel economy.
Quick Pressure™ precision tire pressure monitors or tire monitoring valve caps make it easy for drivers to check tire pressure at a glance without a tire pressure gauge. Our valve monitors indicate when tires are under-inflated by as little as 10 percent.
