Below, you’ll see nine common questions about tire pressure. These are the same questions that are also featured in the video guide below, so you can choose between a video guide or text guide to your Ford vehicle’s tire pressure. Learn these nine things, and you’ll know everything you need to about tire pressure. 

What is tire inflation pressure? 

Tire inflation pressure is the measure of the amount of air within a tire. This is true whether you are talking about car tires or bike tires. This measurement is used to properly inflate tires. 

Are tire-pressure monitor sensors accurate? 

We can’t claim that any sensor or gauge will be 100% accurate. However, they will be close enough to get you the information you need. Their consistency will help you make a good judgment. 

Is there any difference in inflation pressure for tires in winter vs summer? 

No matter the season, you’ll want to inflate from cold tire pressure. Inflating a warm tire might get different results. You can inflate it in a cool garage for good results. 

How often is it recommended to check tires and pressure? 

We recommend inspecting your tires before each drive. Simply walking around and pushing gently on each tire can give you a good feel for their normal firmness. If they ever feel flat, you’ll know that you need to fill them up. Check them at least once a month. 

What effect does cold weather have on tire pressure? 

For every ten degrees drop in temperature, the pressure inside of your Ford vehicle’s tire will go down by one pound per square inch. Cold air is more condensed than warm air, which accounts for the difference in tire pressure. It does not mean that your tire is leaking. 

How does low tire pressure affect vehicle safety? 

Tires with low pressure will touch the ground at more contact points. This increases friction on the tires and wears them down faster. You’ll have to replace tires more frequently to prevent tire blowouts.  

How low does tire pressure need to be before the TPMS warns a driver? 

The TPMS is the Tire Pressure Monitor System in your Ford. This may differ by model, but a TPMS is required to come on once a tire is 25% below the recommended inflation. That’s a pretty low tire, which is why it is always good to do your own checks. 

Where can the recommended tire inflation pressure be found? 

The manufacturer’s recommendation for tire pressure will be found on a sticker on your vehicle. This is typically located inside the driver’s door, as seen in the video below. Your vehicle’s owner manual will also have this information. 

What is a recommended and reliable tire pressure gauge? 

We recommend digital gauges for being easy to read. Dials that look like a clock-face are also easier to read. You can keep a gauge safe with a carrying case.
