Tires are where a car meets the road. A vehicle’s steering, suspension and braking systems all depend on tires to perform at their best. Get the most out of your tires with proper tire care.
Over- or under inflation can cause irregular tread wear, poor steering and braking response, reduced traction, and even complete tire failure. Underinflated tires also create more rolling friction, requiring more energy to maintain speed and resulting in poorer fuel economy.
A quick tire inspection will nell you about the condition of not only your tires, but also your steering and suspension systems.
Rotating tires extends their service life and helps keep tire treads wearing evenly. Rotate tires at every oil change or every six months. Different types of tires require different rotation patterns. Check your owner’s manual for the advised rotation pattern.
Tire Rotation Patterns
Know your tire rotation pattern and save miles on your tires.
PRO TIP: This is a good time to perform a thorough inspection of each tire and find signs of worn steering and suspension parts.
How to Check Your Tire Pressure:
1. Find the tire information placard inside the driver’s door or door jam. It will specify the suggested tire pressures for the tires, including the spare.
2. Remove the valve stem cap and quickly depress gauge onto valve stem until air stops leaking out.
3. Repeat this process on each tire.
PRO TIP: Keep a pressure gauge in your glove box so it’s always accessible. If it is low, add air until it reaches the right pressure and screw the cap back on.
Checking Your Tires’ Wear Patterns
Excessive outer tread wear — caused by under inflation.
Excessive center tread wear — caused by over inflation.
Feathering— usually caused by incorrect wheel alignment or worn steering parts.
Cupping — caused by bad shock absorbers or worn suspension and steering parts.
Check for shallow tread depth and cracking.
Tread depth should be greater than 4/32”. Driving on wet or snow-covered roads will require deeper tread depth.
Check for cracking and blistering of the rubber on the side wall and between the treads. If any cracks or blisters are visible, the tire needs to be replaced.
PRO TIP: Place a quarter upside down and face out between the treads. If you can see Washington’s whole head, you should consider replacing the tire.
PRO TIP: If the valve stem cap is green, it is probably filled with nitrogen instead of compressed air. Nitrogen and compressed air CAN be mixed, so if you find yourself low on air with no nitrogen in sight, you’ll be just fine using compressed air.
