Did you know that for every 10 degrees (Fahrenheit) the temperature rises, the pressure in your tires goes up 1 PSI (Pounds Per Square Inch). This may not seem significant, but in the summer, when temperatures fluctuate widely between morning and afternoon and vacation miles put extra stress on vehicles, that difference in PSI can mean a lot. It is especially important to check your tire pressure and general tire condition during the summertime.
This is because driving on under or over-inflated tires (the latter is more common when it’s hot) can reduce gas mileage, increase the rate of tire wear, and even make your vehicle susceptible to dangerous blow outs.
CHECK AND INFLATE
We assume that as a responsible car owner, you have a working tire gauge and a basic idea of how to use it. Good! Now make it a point once a month this season (and every season) to check your tire pressure first thing in the morning. In order to get an accurate reading, you have to test the tires when they are “cold.” According toC,G, & J Inc, cold tires are tires that:
have not been driven for more than one mile
have been out of direct sunlight
parked on hot pavement
warmed by hot daytime temperatures
Checking the tires in the morning is indeed the best way to ensure that they are “cold.”
From there, be sure to check the side of the driver’s side door or the owner’s manual for manufacturer recommended PSI. Note: This is different from the Max PSI listed on the driver’s door. For everyday driving, do not exceed the manufacturer recommended PSI. Keeping your tires inflated to that specification saves gas and reduces strain on the suspension system. If you are driving with a heavy load, it may be appropriate to inflate the tires to the max PSI as listed on the sidewall (or to the PSI listed in your owner’s manual for the expected load).
Over the course of the day, especially when it is hot, you can expect your tire pressure to sometimes meet or exceed the max PSI, and that’s okay as long as they start at the manufacturer recommended specification.
Keeping tires inflated to the proper pressure is one of the best things you can to do maintain your vehicle and keep your family safe on the road this summer. Also, don’t forget to make sure that the tires are in good condition.
If you need your tires changed or suspension repaired, call, contact or come into any of our three American Pride Automotive Locations.
