Tread Carefully: Learn More About Your Tire PSI

Let’s do our blog a little differently this time (FAQ STYLE). Frequently asked questions when it comes to PSI and tires. If there’s any we missed be sure to contact your local Russ Darrow and ask any questions you might have, we’d love to help.

Q: What does PSI stand for?

A: PSI stands for pound per square inch. 

Q: What should my tires PSI be?

A: Usually ranging between 30-35 PSI

Q: How do I know what PSI my tires should be?

A: Your vehicle’s recommended tire pressure can typically be found on a sticker inside the driver’s door. It’s also usually listed in the owner’s manual.

Q: What if my PSI is too low?

A: Tires that are driven under-inflated generate excessively high heat levels that can weaken the tire to the point of failure. At high speed, a rapidly deflating tire can cause loss of vehicle control.

Q: What if my PSI is too high?

A: An over-inflated tire will result in harsh ride quality and will cause uneven tire wear.

Q: How often should you check your tire pressure? What about in the winter?

A: Once a month, and in the winter every two weeks.

Q: How to check your tire’s pressure?

You can purchase a tire pressure gauge to keep in your vehicle, or depending on your location some gas stations, or other vehicle servicing locations, costco etc,  have gauges built into their air pumps.

Q: What Determines The Vehicle Manufacturer’s Pound Per Square Inch (PSI) Recommendation?

A: Ride comfort and performance, load capacity, traction and wear and fuel economy.

Q: How does PSI relate to fuel efficiency?

A: Incorrect tire pressure can even have you headed to the pump more often. You can improve your gas mileage by up to 3% simply by keeping your tires inflated to the proper pressure.

Q: Any final tips or tricks?

A: Don’t wait until your tire pressure sensor goes off to check on your tires. Try to get to a location where you have to drive less than 3 miles to fill up your tires otherwise your tires will be warm and that changes the PSI before you fill them up.
