Everything You Should Know About Tyre Pressure


Updated on:

We received a lot of inquiries like this from our community, so let’s take a closer look at tyre pressure today, don our geeky glasses, and learn all you need to know about your tyres.

What Tyre Pressure Should I Use For My Car?

After conducting many tests and calculations, the manufacturer has calculated the appropriate tyre pressure for each vehicle model. On the sticker or card inside the driver’s door of most recent automobiles, you may find the recommended pressure. The owner’s handbook often contains the information if there isn’t a sticker. As a result, after a lengthy stay, check the pressure; often, this may get done first thing in the morning.

How Should I Check My Tyre Pressure?

You should periodically check your tyre pressure after you are aware of the required pressure for your car from the manufacturer to ensure that you are in excellent health.

You can check the pressure in your car tyres at home, the technician, petrol stations, and auto parts stores. At-home pressure checks require the following:

  • Measurement of tyre pressure (Digital or Regular)
  • compressor for air
  • Your phone or a pen and paper

Step 1: Test with cold tyres.

If at all possible, begin with cold tyres since the recommended pressure for cold inflating is the pressure at which tyre pressure considerably fluctuates with temperature. To avoid the heat from the friction of the previous drive and before the temperature rises, we often check the pressure after one night of rest.

Step 2: Use a gauge to check the tyre pressure.

To stop the hissing sound, unscrew the valve cap and firmly push the tyre gauge against the valve stem. If the gauge is securely attached to the tyre, there should be a reading.

Step 3: Write the readings down.

Next you may write down the pressure for each tyre and compare it to the recommended psi you read in the owner’s handbook or inside your driver’s door. Make sure you read everything carefully because some vehicles have different suggested pressures for the front and rear tyres.

Step 4: Fill your tyres to the recommended pressure

If you discover a tyre that needs inflating, utilise the air compressor to do it. A petrol station or an auto parts store both sell and rent air compressors. To ensure that the reading is correct and the tyres are cold, remember to let them rest for at least 30 minutes.If you must fill your tyres while they are still hot, fill them to a pressure that is 34 psi higher than recommended, and then check your gauge once the tyres have cooled. the impact of pressure on fuel efficiency. While filling the tyres, it’s acceptable to slightly overinflate them because you may release the air using the gauge.

Step 5: Reassess the tyre pressure.

Use your tyre pressure gauge to check the pressure one more after filling the tyres to make sure it is within a safe range. If they are over-inflated, release some air by pushing the gauge firmly against the valve stem.

How Can Correct Tyre Inflation Get Maintained?

We strongly advise that you check your tyre pressure each time you inflate a tyre, after each temperature change of 10°F (5.6°C), and once every 30 days since proper tyre maintenance is crucial to the overall operation of your car.

Remember to check the pressure before the TPMS light illuminates because a typical TPMS may:

  • unable to detect a slow air loss
  • cannot identify tyres that are actualy overinflated
  • unable to identify which tyre is basically underinflated
  • cannot operate if the dashboard signal from the TPMS is not there.

As a result, we urge you to frequently check your pressure, especially before a long journey or while hauling large loads. The following part will describe how temperature significantly impacts tyre pressure.

How Do Temperature and Tyre Pressure Relate?

The variation in pressure with temperature is then increased to 2 psi for every 10°F when it comes to commercial truck tyres, which are frequently inflated to above 80 psi.

How tyre pressure affects fuel economy

How much additional effort would you need to use to keep a ball rolling on ice if there was no friction between the two surfaces?  (Thanks, Newton). The same holds true for how much petrol you use when you’re driving. Fuel economy is greatly impacted by rolling resistance between your tyres and the road. By now, we should all be familiar with the reasoning behind this: low tyre pressure results in a bigger contact patch, which increases rolling resistance and reduces fuel efficiency.
