Air Pressure Check
The Benefits of Correct Air Pressure
Experts agree that keeping the correct air pressure in your tires is as important as giving your engine a tune-up. In fact, the economic benefits may be even greater. With the right amount of air pressure, your tires wear longer, save fuel, enhance handling, and prevent accidents. Failure to maintain the correct air pressure can result in poor gas mileage, reduce tire life, affect vehicle handling, and cause vehicle overloading. If you consider these factors, then the need to routinely check your tire pressure is even clearer.
Because tires do so much without appearing to need attention, it's easy to forget about them. However, tires do lose pressure each day, through the process of permeation. In cool weather, a tire will typically lose one or two pounds of air per month. In warm weather, it's common for tires to lose air at an even higher rate. Tires are also often subjected to flexing and impacts that can diminish air pressure as well. It's important to realize that refilling your tires is as important as refilling your gas tank. In fact, associating the need to refill your tires with the need for refilling your fuel supply can also be a useful reminder.
The correct air pressure may be found in the vehicle owner's manual or on the tire placard (attached to the vehicle door edge, doorpost, glove box door or fuel door). The placard tells you the maximum vehicle load, the cold tire pressures and the tire size recommended by the vehicle manufacturer. If you have trouble, visit Raffield Tire for assistance.
In addition to routine air checks, other circumstances necessitate a visit to the air pump. Seasonal changes or altitude changes create a rise or drop in air pressure (for every 10 degrees change in temperature, tire air pressure changes 1 psi). Perhaps the most overlooked factor is vehicle loading for trucks and RVs. Since these vehicles can be configured and loaded in many ways, actual tire loads should be used to determine the proper inflation pressure. This is best determined by weighing the vehicle. Keep in mind that vehicle loading can change from trip to trip.
Properly checking tire pressure requires an accurate air gauge. Many people believe that they can check air pressure just by looking at the tire and judging the sidewall appearance. Also, many people use air meters at service stations, which can be grossly inaccurate due to exposure or abuse. Invest in a quality air gauge. For trucks and RVs, use a dual-head inflation gauge that is calibrated up to 120 psi at 2 psi increments.
In this example, add 3 psi in the right rear tire to match the other rear tire's warm reading. When the tire returns to cold pressure, it should end up at the recommended pressure.
How can routine air pressure maintenance impact our environment? Consider that fewer tires per year would end up in the landfills and scrap heaps that trouble our ecology. It's estimated that most drivers lose from 10% to as much as 50% of tire tread life due to underinflation. That's a significant statistic. Now consider the extra fuel we burn to push cars along on soft, underinflated tires. Tires require extra energy to roll if they are underinflated. While the statistics vary widely and can be somewhat inconclusive, the implications are staggering. Maintaining tire pressure may seem like a low priority in our busy daily routines, but it adds up to big environmental consequences.
