Tire Air Pressure Chart Navigation
Understanding how to properly read and navigate a tire air pressure chart is helpful when determining how and when to inflate or deflate your tires air pressure. Being able to read this chart and properly check your tires PSI, you will increase gas mileage, increase safety, and increase your tires life.
For example, if your recommenced tire pressure is 32 PSI and it’s 40 degrees Fahrenheit, you should inflate your tires PSI to 35, based on our tire air pressure chart.
Time needed: 2 minutes.
How to use a tire air pressure chart step by step
- Find your vehicle’s recommended tire pressure
Located either on your door jam sticker or owners manual.
- Find your vehicle’s recommended tire pressure on our chart
Hint: At the top in dark blue
- Determine the temperature outside in degrees Fahrenheit
- Match outside temperature to chart
Match the outside air temperature to the column on the left side labeled temperature on the tire air pressure chart.
- Follow the chart across to get your tires recommend PSI
With your finger still on the outside temperature the chart, follow the chart to the right until you reach your original equipment manufacturer (OEM) recommended tire pressure. The number there will be the correct PSI for your tire at that specific outside temperature.
Should I Inflate My Tires in Cold Weather?
A tires pounds per square inch (PSI) inevitably drops or decreases in tires during cold weather. Therefore, yes you should increase or inflate your tires in the cold weather using our tire air pressure chart and a portable tire inflator.
The reason you should do this is because the recommended tire pressure for your vehicle is recommended using “cold” tire readings and measurements.
Cold weather for tires means the tire temperature is less than 65 degrees Fahrenheit. A vehicle’s tire PSI can increase by 1 to 2 PSI per 10 degrees Fahrenheit, meaning that when the temperature gets warm out (above 65 degrees Fahrenheit), you’ll more than likely need to lower or decrease the pressure in them and vice versa for cold weather.
This is done in order to maintain proper tire pressure, increase safety, and prolong your tires lifespan by preventing signs of bad tires.

If you have tire pressure sensors (TPMS), they will tell you when your tires pressure is too low, as well as tell you when they are too high.
This nifty device will allow you to easily monitor your tire pressure without ever having to leave your vehicle or physically check your tire pressure with a gauge.
However, you should never solely rely on your TPMS indicator, they can be faulty. You should always check your tires manually to insure you, your passengers, and vehicle safety.
Long Drives vs Tire Air Pressure
Over the course of a long drive, as a result of alternating between braking and acceleration and of course steering, tires will warm up.
A tire heating up means a tire will increase in pressure. However, if the weather/outside air temperature is too cold, they typically don’t get warm enough to turn off a TPMS alert or inflate your tires PSI to the recommended setting. (If your PSI is too low)
Pro Tip: Giving up on your goals is like slashing the 3 good tires you have left. Don’t let a minor set back destroy your dreams.Tweet
Lower or higher than recommended tire pressure is dangerous and could lead to premature tire wear.
Overall, properly inflated tires endure less wear and tear and therefore last longer. You should never overlook low or incorrect tire pressure.

How Often Should You Check Tire Air Pressure?
As a smart driver, you should check your tires air pressure every time you fill up your gas tank. This will take no time at all and can easily be done while your car is filling up. This quick preventative measure will save you hundreds in preventable tire damages.
It is a good idea to always keep a handheld pressure gauge in your car so you can perform this quick check. However, if this method seems to be excessive or you find that you are checking your tires pressure too often and getting the same results, try to check them at least once a month.
Depending on the size and type of tire air pressure will differ. Check your door jam or owners manual for correct PSI. Never go by what is listed on the tires sidewall. This PSI is the maximum PSI for your tire, not what your vehicle recommends. If you follow this pressure your tire will be over inflated and create premature wear in the center of your tire. Additionally, outside air temperature effects your tires air pressure.
Symptoms of When to Check Tire PSI
Most of the time, it’s hard to spot or identify an under or over inflate tires. Severe tire damage or a completely flat tire means you could need a new tire. Learn to see the tell, tale signs and symptoms of tires that are under or over inflated.
- Your car isn’t handling as well as it usually does.
- There are cracks in the tire.
- Your steering wheel is shaking or vibrating.
- Tire looks flat
- Uneven wear
