Tire Inflation
Improper tire pressure causes irregular tire wear which creates and amplifies imbalance, resulting in wheel vibration. Wheels can be balanced and rotated to greatly reduce or stop the vibration.
As you are diligent to check your tire pressure monthly, and bring your car in for regular wheel rotation, you will greatly extend the life of your tires. Remember, our 4-Wheel Rotation service is still only $12.50 for most vehicles!
Inflate -- Rotate -- Evaluate
Tires can lose one PSI (pound per square inch) per month under normal conditions. In addition, tires can lose 1 PSI for every 10 degrees F temperature drop.
- Inflate -- Check your tire pressure monthly.
- Rotate -- Rotate tires every 5,000 miles.
- Evaluate -- Routinely look for signs of tread wear or damage.
Always check your air pressure, especially if you're carrying extra weight. Lower pressure increases heat which will result in tire damage.
Tire Inflation Q & A
How can I tell if a tire is properly inflated?
"Eyeing" a tire doesn't work, especially with radials which, when under-inflated 5 PSI or less, tend to "look" alright. You must use a tire pressure gauge. Gauges built into air pumps at service stations are often inaccurate. You can purchase a hand-held gauge for as little as $2, which is a wise investment.
What happens when there is too little air in the tire?
Wear will show on the sides or shoulders of the tire. When severely under-inflated, a tire is overloaded, flexes more, develops head build-up and runs hot which can cause damage and possible failure. Less severe under-inflation results in sluggish handing and response.
What happens when there is too much air in the tire?
Wear will show on the middle of the tread. Beyond causing the vehicle to ride harder, over-inflation increases stress on the tire, affects traction and strains the suspension system.
What about checking tires on a long trip?
Inflation pressure will increase 4 to 8 PSI (or more) when the tire becomes hot from high speeds and longer drives. Never reduce air pressure when tires are hot.
How can I save money with properly inflated tires?
You will save money in both tires and fuel costs. Tire technology engineers report that the life expectancy of a tire drops approximately 25% with under-inflated tires, and fuel efficiency drops significantly as well.
