Tire inflation pressure is the level of air in the tire that provides it with load-carrying capacity and affects the overall performance of the vehicle. The tire inflation pressure is a number that indicates the amount of air pressure– measured in pounds per square inch (psi)–a tire requires to be properly inflated.

Manufacturers of passenger vehicles and light trucks determine this number based on the vehicle’s design load limit, that is, the greatest amount of weight a vehicle can safely carry and the vehicle’s tire size.The proper tire pressure for your vehicle is referred to as the “recommended cold inflation pressure.” (As you will read below, it is difficult to obtain the recommended tire pressure if your tires are not cold.)

Because tires are designed to be used on more than one type of vehicle, tire manufacturers list the “maximum permissible inflation pressure” on the tire sidewall. This number is the greatest amount of air pressure that should ever be put in the tire under normal driving conditions.

CHECKING FOR PRESSURE
It is important to check your vehicle’s tire pressure at least once a month for the following reasons:
- Most tires may naturally lose air over time.
- Tires can lose air suddenly if you drive over a pothole or other object or if you strike the curb when parking.
- With radial tires, it is usually not possible to determine underinflation by visual inspection.

For convenience, purchase a tire pressure gauge to keep in your vehicle. And as always, if you have any tire related questions please visit your local Tire Pros. Click here (http://www.tirepros.com/dealers.php) to fine a Tire Pros near you.

Checking for Wear
The simplest way to check for wear is to do the penny test. Place a penny inside the tire tread with the top of Lincoln’s head facing towards the tire. If you can see the top of Lincoln’s head, your tread is worn and needs replacing. The legal limit for tire tread is 1/16″.

Checking Alignment
It’s always a good idea to regularly check your tires for proper alignment. This way, you’ll ensure your tires will last the full life for which they were intended. Ask us for an alignment inspection today.

Checking Tire Pressure
Check your tire pressure monthly when tires are cold. Air pressure changes 1-2 pounds for every 10 degrees of temperature change. Always keep the vehicle manufacturer’s recommended air pressure in all your tires, including your spare.

Selecting the Right Tire
When purchasing a tire: buy the right size; consider factors such as load-carrying capacity as well as traction, tread wear and temperature grades. There is a difference between the lowest price and the best value.
