I’m getting ready to head to San Antonio tonight with some valuables in my Pacifica. Namely my wife, daughter, son-in-law and grand daughter. You bet I’m doing my pre-trip!

Winter is here and one of the important external factors of tire pressure is temperature change. In fact, for every 10-degree change in temperature, a tire can lose approximately one pound per square inch (PSI).

In checking my tire pressure 3 out of 4 were right at 35psi. I had actually expected more inconsistancy with the extremely cold weather we have had in Houston. The 4th tire was 36psi. I feel comfortable knowing I’ve done my due diligence.

Safety is the focal reason why tire pressure must be checked regularly. Under inflated tires causes accidents due to skidding, hydroplaning, loss of control and the like. Another reason for maintaining it right is fuel-efficiency. The latter is lowered by 1 percent for every 3-PSI under inflation. Hence, a correctly inflated tire equates to 1 free tank each year.

Your tire pressure should be checked at least once a month. Make sure you have a pressure gauge in your glove box or clipped to that CD case on your visor so you have it handy to check the pressure the first of the month (might be a great item to add to your 101 list http://your101.wordpress.com/).

Down the Road – Mike
