How To Use A Portable Tyre Inflator? Simple Step-by-step Guide

The tyre manufacturers have put some extra effort into creating a product that improves fuel economy and tyre life and cuts down tailpipe emissions. As a consequence, users get different sorts and advanced technology tyres, like silica-based and low-rolling resistance tyres.

Therefore, you are unable to obtain benefits from such technology if you aren’t able to maintain correct tyre pressure. According to experts, checking the tyre pressure level in your vehicle once every fortnight is essential. Unfortunately, most of us usually neglect it, which is why most issues occur, but there is nothing to worry about.

We are here with remarkable solutions, as you should have a portable tyre inflator. Now you must be wondering how to use a tyre inflator? Is it important to get professional assistance? Let’s uncover such aspects in forthcoming points.

How To Check The Pressure Level In The Tyre?

Start with cold tyres:

The vehicle manufacturers usually specify PSI as the tyres are cold when parked for at least 3 hours or more.


If you drove your vehicle within less than a mile, like 1.6km at a slow speed, then the PSI united is needed for the pressure gauge to serve accurate readings.

Write down PSI every time:

If the rear and front tyres need different pressure levels, pen down the correct PSI to make sure everything is clear regarding checking the right pressure levels. Write down the reading and repeat it often for each tyre to get better results.

Check the manufacturer’s suggest PSI:

Try to look on the driver’s side door jamb or the manual for owners to find out the suggested cold tyre PSI for rear and front tyres. If you cannot find out, you should consider the vehicle manufacturer, dealer, and qualified tyre professional.

Fill in the suggested PSI:

Experts suggest using the air compressor to refill the tyres with lower pressure. There’s a fact you should know that air compressors are present in different ranges, and it provides numerous results. First, fill every tie by placing the end of the hose on the valve stem and then pressing the lever.

Using a gas station air compressor shows that tyres might be hot. If it is important to make certain adjustments to inflation pressure when they are hot and set the pressure to 4 PSI or above. After that, recheck the inflation pressure again when they are cold and use a gauge to measure the pressure level again.

Check time pressure monthly:

Try to make such points a procedure, a monthly ritual. Try to check the tyre pressure in the best way possible to ensure that it will never dip. The digital tyre pressure gauge can be extremely helpful in serving accurate readings.

How To Inflate A tyre?

Maintaining accurate tyre pressure is essential for your vehicle. It is vital for several reasons that can primarily affect the following:

  • tyre lifespan
  • Vehicle handling
  • Fuel economy
  • Braking distance

Ensure that your tyres are accurately inflated as it is a simple process, but shockingly people need to learn how to do it and when to do it. Mostly, people aren’t confident enough to get it done without professional assistance.

But they should learn how to use a tyre inflator? Via a little guide that is mentioned below for their convenience. Just follow the steps to ensure that the tyres are always at the correct pressure level.

Step-by-step Guide On How To Use tyre Inflator:

Step 1: find out what is the correct pressure for your tyres

There are multiple sources to get information is present. The vehicle’s owner’s manual is also there to make things easier. Additionally, many different cars contain a small sticker on the inside or outside of one of the car doors or inside the filler cap.

Pressure gauge

Initially, it would be best if you longed for the connector to use the air inflator, and it should be a 12V power socket that is present in the car. You can get the air inflators with the extendable power cord so users can take closer to every single wheel.

When it comes to precautionary measures, you should keep the engine running so that the compressor doesn’t drain out the car battery.

Step 2: check out the condition of the tyre.

Before considering any further step, you should check the condition of the type. If you have seen or find out a massive puncture on the tyre, then you shouldn’t use the inflator.

The tyre is unable to serve the desired results as it is not able to hold air, so you should get it fixed or swap it with a spare wheel. Feel free to call for assistance to find instant solutions to puncture issues.

Step 3: Determine the level of air

The car tyre pressures usually range from 30-35 PSI, whereas the light trucks often need higher pressure. Some vehicles require the same amount of pressure in every tyre. But others might have different values for rear or front tyres.

The tyres naturally tend to deflate about 1 PSI every month, which affects quality, and users might need to struggle a lot. To eliminate the possibilities of such consequences, check the air pressure in your spare twice every year and consider the following:

Read the car’s manual or your driver-side doorpost to get to know about the recommended tyre pressures. The label should provide the recommended tyre PSI or KPA number.

If your vehicle’s tyre is flat, there are higher possibilities of leak issues. Try to add air by considering the tyre inflator and ensuring that it holds air.

Recheck the tyre pressure and notice if it drops, then it indicates the leak issues. It should be taken to the tyre store where they will repair it.

  •  It is a sign that you should have a spare tyre as it can be helpful in case of an emergency.

Step 4: Prepare to pump

  • Remove the valve stem caps: you need to screw them back later to keep them aside or keep them in your pocket. Try to leave each stem cap on its valve until you are about to pump up the tyre. This is how the caps will spend most of the time in the right place, and vehicle owners don’t need to be worried about anything. 
  • Find out the air pump: there are multiple types of air pumps available in the market. It would help if you used automatic air compressors that are more expensive but much faster. You can use the manual floor pump or portable ones that fit your necessities and budget. 
  • Ensure that tyres are cold: the users need to ensure that the tyres are cold enough to make things happen. It would be best if you got the job done when the type is driven less than 2 miles while being flat. If you have driven it around a couple of miles, then the pressure gauge reading will not be accurate.

Step 5: suggested pressure levels

When you think that you have added enough air, then pull the hose away. After that, use your pressure gauge to read out the pressure levels.

Use Inflator To Inflate Tyre

Most of us should are required to have 30-35 PSI but look for the specifications for a car to ensure that your vehicle may or may not require the same levels. Add air after gaining information regarding accurate pressure levels. Moreover, if you have reached an accurate pressure level, then:

  • You should release air from the tyre by using a depressed center pin of the valve stem. You can use a fingernail or tool to get things done. Therefore, you will hear a steady hiss sound as the compressed air jets deal with over-inflated tyre issues.
  • The experts state you should ensure that tyres have accurate pressure even when they have low PSI units. According to research, pressure levels below 3PSI burn 1% more fuel. With this, you can suffer up to 10% more tyre wear and might need to face a lot of damage.

Step 6: Replace the valve stem cap

When you are done adding air to every tyre, ensure to replace the stem cap. It is not a mandatory step, but it can seal up the value and make sure that the tyres are less likely to lose air. The valve is designed differently as it releases less air unless anything depresses it, like a stray object, finger, or a twig.

Step 7: Repeat the process for every tyre

There are some cases where the hose can’t reach, so feel free to move the car a little closer and turn it around. But there is one thing that you should keep in your mind: each pump session only runs for a specific time. So it would help if you were fast enough to get the job done within a couple of minutes.

Begin the pumping process with the correct pressure. But remember that a lot of vehicles have numerous pressures for rear and front tyres. Most of the pumps will have a couple of different ways of displaying the pressure, as it can be a BAR or PSI.

A common way to measure the pressure level in the United Kingdom is by using a BAR. If you only want to know about the value of PSI, then press and hold the BAR/PSI button to unveil accurate results.
