Tire Inflators Buying Guide

You should always ensure that you know everything about buying the right tire inflator for your vehicle or even your bike. The more you know, then the easier it will be for you to make the right choice, so keep reading on to find out more.

Why is Tire Pressure Important

You must know the tire pressure and the limit that your current tire can handle. If you don’t have the right tire pressure, you will be using more gas, and your vehicle will be much safer. This would also keep your tires in better condition than they might be if they weren’t inflated properly.

How to Properly Check Your Tire Pressure

You should make sure that you have a tire gauge in your vehicle to check the pressure easily. You can also use these machines if they aren’t turned on for inflating, and you would need to push the air hose onto the tire. Once it is placed on, make sure to push the locking mechanism into place, and it will tell you what the pressure currently is.

How to Properly Inflate your Tires

If the pressure in your tires is low, you will want to inflate them to the proper level, which you can find on the tires themselves. You should ensure that you are getting your machine out and installing it on the tires and then let it go. You can set the pressure level that you want automatically, or you can watch it and then turn the machine off.


What to Look for When Buying a Tire Inflator

  • You should know what factors to consider when buying a tire inflator before you start to look. This would help in making the decision process easier, and some of the top factors include:
  • Storage and portability – Make sure that you are thinking about how the machine will be stored and its size so it can be moved around easily.
  • Inflation time – Another thing to consider is how long it will take to inflate a basic 35PSI tire since you aren’t want to wait a long time, especially if you are on the roadside.
  • Automation – You should also consider the automation that the device can do, including turning itself off after setting the desired pressure.
  • Size of the tire – Consider what size tires the machine would handle since not all of them can deal with a larger vehicle or even an SUV.
  • Duty cycle – Also, think about the duty cycle and how long it will need to cool down after usage since you want to know how soon you would be able to use it again afterward.

Ensure that you are thinking about all of these factors, and it would be critical to use them when you are comparing the models when making your choice.

What is the Size of Air Compressor I Need to Fill Truck Tires?

If you are hoping to fill up your truck tires and need an air compressor, you need to be aware of the size. There are plenty of options for this, and you want to know what size tank you would require, which should be around 6 gallons. You would need to choose a larger one for a larger vehicle, so go ahead and find the right one.

What Does PSI Stand for in Tire Pressure?

You might be wondering what PSI stands for, and it means pounds for every square inch, which can help you know the right pressure limit for your tires. The normal PSI for a small vehicle tire is 35PSI, so make sure that you are looking at your tires and seeing their limit.


FAQ

How long will these machines last?

These can last for quite a long time depending on how well you maintain them, but normally they will last for between 4 to 8 years. You should make sure to replace it if you find any damage to the electrical cord or the air hose.

Should I leave my vehicle on while the inflator is working?

You should keep the vehicle on just enough so that the power is running, but the engine shouldn’t be. The only reason that you need the power going is so that it can help the device to start and work.

What is the lowest PSI that I should be driving on?

If you don’t have your machine ready or if it isn’t working when you need it, then you need to be aware of the lowest possible PSI that you can drive on. The lowest that you should ever contemplate driving on is 20PSI since anything is thought to be a flat tire.


Final Thoughts

You should always make sure that you are ready for any emergencies that might happen, including a flat tire. You never want to be caught unaware or stuck in a location that you don’t know, so ensure that you buy one and have it placed and charged in your car. You should make sure that you are thinking about the tire size you would have to fill, duty cycle, and much more before comparing these models and deciding which to buy.
