So, today we explore the importance of Tire Pressure as relates to your wheel alignment. Many people have no idea that a temperature drop in winter or rise in summer can greatly affect your tire pressure, but all of us know that if there is an issue with your tire, it will affect your wheels and therefore alignment!
In 2003, all vehicle manufacturers were directed to place tire information labels in a standard location and follow the same format. Tire information labels identify the Original Equipment tire sizes and inflation pressures (including the spare), along with the vehicle weight capacity.
In addition, the new vehicle owner manual must also reflect the five subject areas:
· Tire labeling
· Recommended tire inflation pressure
· Glossary of tire terms
· Tire care
· Vehicle load limits
Vehicle manufacturers can also list alternate tire pressures based on load and/or speed in the owner’s manuals.
Vehicles produced between 1968 and 2003 have the original tires size(s) and inflation pressures (including the spare) listed on a vehicle placard (sometimes alternate pressures based on load and/or speed conditions are provided).
The 1968 – 2003 labels are found in one of the following locations:
· The driver-side door or doorjamb
· Rear passenger doorjamb of Ford sedans
· Fuel filler door
· Glove box or center console door
· The engine compartment
As far as temperature affects, a good rule is that pressure varies 1 PSI for a temperature change of 10 degrees Fahrenheit. So for example, if you measure your tire pressure at 90 degrees Fahrenheit, the “standard” pressure at 68 degrees would be about 2 PSI less than what you measure. If you want, say, 44 PSI at 68 degrees, but it’s 90 degrees outside, then put some extra air in your tires, wait for it to adjust to the outside temperature, and bleed or top off the tire until the gauge reads about 46 PSI.
Just remember to maintain your pressure and perform your scheduled QuickTrick™ routine measurements and your car performance will be better, your tires will last longer and you will be the master of your own “wheel” domain!!
Have a great week!
