At Galles Chevrolet, we have a lot of people asking what the best tire pressure for their tires is. Typically they assume that the maximum PSI listed on the sidewall is what they should be going by. Unfortunately, the maximum PSI and the OPTIMUM PSI aren’t the same time. Sometimes, the maximum is actually doing more harm than help. Which is why it’s important to find the perfect balance.
Let’s talk about what the maximum PSI is. Somewhere on the sidewall of your tire, just below the big, bold letters of the manufacturer, for example, you might have noticed the words, 'Max. Press. 35 PSI.’ That number tells you the maximum cold pressure needed for your tire to carry its maximum load. Now, that is the absolute MOST tire pressure your tire can have. Can being the operative word here. What it CAN have, not what the tire should have. We mention ‘cold’ pressure because that means you’re filling up your tires at the ideal time which we’ll talk a bit about later in this blog. Usually, your tire’s maximum tire pressure is either 35 or 44 PSI.
What happens if you inflate your tires to the max PSI?
The handling characteristics change
Since tires inflated to the max can’t give as much on the sidewall, you might see superior cornering, but it could be at the risk of your braking threshold. One quick corner and your back end could slide out.
The life of your tire decreases. When your tires are inflated too much, the rubber rounds out at the top of the tire when you’re driving, and the center will quickly wear out. You’ll also reduce your traction and you could even cause a blowout. Check out our post on avoiding blowouts.
The best time to check your tire pressure is every time you fill up for gas, every 10-degree change in temperature, or every 30 days. When adding air to your tires, try to do so when they are cool. It’s preferable to add air after your car has been sitting in the shade for a while. If you want to make sure your tires are inflated to the right pressure before you head out for a drive, stop by Galles Chevrolet. Just pull up and we’ll check your tire pressure and top up your tires if needed. Plus, we can even re-torque your wheels while we’re at it so you know you’ll have a smooth ride.
