Proper tire care and safety is simple and easy. The Rubber Manufacturers Association (RMA) recommends taking five minutes every month and before every long trip to check your tires, including the spare. Just remember to "Be Tire Smart - Play Your PART: Pressure, Alignment, Rotation, Tread."
Your Tire Maintenance Checklist
How to Check Inflation Pressure Look for this information in your vehicle. Refer to your vehicle's owners manual for the proper level of inflation; it may also be posted on the door post or in the glove box.
- Under inflation results in unnecessary tire stress, irregular
wear, loss of control and accidents. A tire can lose up to
half of its inflation pressure and not appear to be flat!
How to Check Inflation Pressure
- A bad jolt from hitting a curb or pothole can throw your
front end out of alignment and damage your tires. Have a tire
dealer check the alignment periodically to ensure that your
car is properly aligned.
See More on Checking Your Alignment
- Regularly rotating your vehicle's tires will help you achieve
more uniform wear. Unless your vehicle's owners manual has
a specific recommendation, the guideline for tire rotation
is approximately every 5,000 miles.
Details on Rotating Your Tires
- Advanced and unusual wear can reduce the ability of tread
to grip the road in adverse conditions. Visually check your
tires for uneven wear, looking for high and low areas or unusually
smooth areas. Also check for signs of damage.
How to Check Tread
Always practice good driving habits
When you check the inflation pressure, make sure the tires are cool - meaning they are not hot from driving even a mile. (Note: If you have to drive a distance to get air, check and record the tire pressure first and add the appropriate inflation pressure when you get to the pump. It is normal for tires to heat up and the inflation pressure inside to increase as you drive. Never "bleed" or reduce air pressure when tires are hot.)
Check inflation pressure once a month and before long trips.
If you overfill the tire, you can release air by pushing on the metal stem in the center of the valve with a fingernail or the tip of a pen. Then recheck the pressure with your tire gauge.
Replace the valve cap.
Remember to check the spare. (Note: Some spare tires require higher inflation pressure).
If your car's suspension system is out of alignment, your tires will wear unevenly and you may experience handling problems. Potholes and rough roads can contribute to problems with alignment.
Front-wheel drive vehicles, and those with independent rear suspension, require alignment of all four wheels.
Have a tire dealer check your alignment periodically as specified by your vehicle owner's manual or if handling problems develop, such as "pulling."
Also have your tire balance checked periodically. An unbalanced tire and wheel assembly may result in irregular wear or vibration.
Each tire on your car supports a different amount of weight; this unequal weight distribution causes your tires to wear at different rates. By rotating your tires, you can extend their useful life.
If your tires show uneven wear, ask your tire dealer to check for and correct any misalignment, imbalance or other mechanical problem involved before rotation.
Refer to your vehicle's owners manual for rotation recommendations. If no rotation period is specified, tires should be rotated approximately every 5,000 miles.
Sometimes front and rear tires use different pressures. After rotation, adjust tire inflation pressure to the figures recommended by the vehicle manufacturer.
the tread is worn down to 2/32 of an inch, tires must be replaced.
tires have "wear bars," which are small, raised
bars of rubber in the groove that indicate when tires are
worn out. If your tread is worn down to the wear bars, it's
time for a new tire.
penny is a reliable tool to check tire tread.
1. Take a penny and put Lincoln's head into one of the grooves of the tire tread. If part of his head is covered by the tread, you're driving with the legal amount of tread.
2. If you can see all of Lincoln's head, it's time to replace the tire.
check your tires for signs of uneven wear. You may have irregular
tread wear if there are high and low areas or unusually smooth
areas. Also make sure no nails or other objects are embedded
in the tire. Consult your tire dealer as soon as possible
if you see problems.
Tire Pressure Monitoring System (TPMS) Vehicles equiped with Tire Pressure Monitoring Systems (TPMS) can help motorists detect loss of inlfation pressure. Federal regulations require TPMS to warn drivers when tires are 25% under inflated. For many vehicles this warning may be too late to prevent damage caused by under inflation. TPMS units are NOT a replacement for monthly tire pressure checks with a gauge.
