It
 only takes a penny to see if your tires are worn or losing tread. 
Examining your tires for wear and tear, along with checking tire 
pressure and alignment, are essential to ensuring your vehicle’s safety 
on the road and helping to improve gas mileage and performance. The 
non-profit Car Care Council recommends that motorists be car care aware 
and check tire condition and pressure regularly.
“The penny test
 is a simple, yet effective, way to check tire tread. If you see 
Lincoln’s head above the tread, you are ready for new tires,” said Rich 
White, executive director, Car Care Council. “Tires are critical to a 
vehicle’s handling and traction, and maintaining proper pressure is 
vitally important to vehicle safety. Underinflated tires are under 
stress and will wear unevenly, causing them to need to be replaced 
sooner. Routinely checking tire balance and wheel alignment reduces tire
 wear, improves handling, and increases fuel economy.”
According to the Car Care Council’s popular Car Care Guide,
 vehicle owners should check the pressure of all tires, including the 
spare, on a monthly basis and more often during colder weather. In 
addition, the tread should be checked for uneven  or irregular wear as 
well as cuts or bruises along sidewalls. Tires should be inflated to 
recommended pressure levels, rotated every 6,000 miles to promote 
uniform tire wear and be replaced if worn or damaged.
If
 the vehicle shakes or pulls to one side, it could be a sign of an 
alignment issue. Because uneven or accelerated tire wear may indicate an
 alignment problem, it’s a good idea to have the alignment checked at 
least once a year. Wheel balance can change as a result of normal tire 
wear and unbalanced wheels can cause rapid wear of shock absorbers and 
struts.
