How to check your Tire Pressure

ACCORDING to a recent study by the National Highway Traffic Safety Administration vehicles with under inflated tires are three times more likely to involved in an accident linked to tire problems than tires with the correct pressure. Low tire pressure does not just affect handling characteristics, and gas mileage but can lead to irreparable tire damage. Tire pressure is important and easy to maintain by following a few simple steps. It is important that you check tire pressure when cold not after driving the vehicle or in the afternoon. Tire pressure can vary as much as 10 pounds here in Arizona from cold in the morning to our warm afternoons after a drive. The basic rule of thumb is for a temperature change of 10 degrees the pressures will change by 1 pound. Add to that a warm tire can increase pressure by 5 pounds compared to the same tire cold you can see it is important to check your tires under the proper conditions.
Having properly inflated tires helps for many reasons some are, properly inflated tire help maximize fuel economy, (with today’s gas prices this simple procedure can save you hundreds of dollars over the course of the year). Improves durability and performance designed to match the needs of your vehicle. Increase tire responsiveness, traction and handling. To increase tire life, you should check your tire pressure at least once a month.

Step 1 is to find out what your tire pressure should be. Forget about the number on the side of the tire that is most likely a maximum tire pressure and is not the correct pressure for your vehicle. To find the correct pressure for your vehicle look in the vehicle owners manual or in the drivers side door jamb for a sticker that has the correct tire size and the correct tire pressures (NOTE) front tires do not always have the same pressure as the rear tires so look at both front and rear.
Step 2 would be to remove the tire valve cap from the tire valve put that somewhere safe as you do want to put the cap back on after you adjust the pressure.
Step 3 is to use a tire gauge to check the pressure. there are several different types of gauges the most accurate is a digital gauge there are stick gauges also they are inexpensive and still pretty easy to use.

After checking your tires you can add or release air as needed if you do not have air available to you make a note as to how much air is needed to get the tires to the correct pressure and then when you get to an air compressor check your pressure again then add the pounds that you were low and recheck the next day.
