This blog is dedicated to providing information about cleaner burning ethanol fuels, but there are some other topics we like to cover from time to time. Today, it’s tire safety.
Experts say you should check tire pressure at least once a month. Why? Because on average, tires lose approximately 1 pound per square inch (PSI) of tire pressure every month. PSI refers to the minimum amount of air pressure needed to support the weight your vehicle when fully loaded. In winter, you may want to check your tire pressure more often. For every 10 degrees F change in outdoor temperature, tire pressure will change by approximately 1 PSI.
Also, to meet legal safety standards in the U.S., a tire’s tread needs to be at least 2/32” deep. Here’s an easy trick to see if your tires pass the “penny test.”
Place a penny in the tread of your tire.
Turn the penny so that Lincoln’s head points down into the tread.
See if the top of Lincoln’s head “disappears.” If it does, your tread is still above 2/32” and you’re good to go. If you can see his entire head, it may be time to replace the tire.
Have a safe summer of driving, and don’t forget to check those tires.
