What should I look for in a tire inflator?

With the tire inflator market overflowing with every brand and tire inflator models you can find, you must get your purchase right. Here are some of the things you should look for in a tire inflator:




A complicated tire inflator is a time waster and can add to your frustrations. It would help if you had something, you can operate smoothly and ready for use whenever you’re ready. It should also include the necessary features to make its usage straightforward.


Size of the inflator


You’re probably looking for a tire inflator that will keep you prepared all the time. Right? If that is the case, you may want to get something you can carry with you in your car boot. For that reason, you need to get something lightweight and compact; it needs to be easy to pack, lift, and carry.


Air pressure gauge


Tires have pressure limits, and you will only know you’ve reached it if you’re using a reliable air pressure gauge. That’s why you may want to get a car tire inflator that comes with an air pressure gauge to keep you updated.


Auto-inflate feature


The feature will make the whole tire inflation process simpler and straightforward. It does allow you to preset the estimated amount of air your tires needs. And all you need is press the ‘Go’ button for the system to wrap things for you.


AC/DC compatibility


You may want to consider needing the tire inflator while you’re stranded anywhere with no electricity, and the only way to power the unit is through the car’s DC cigarette port. That’s why it’s crucial to get a model that is compatible with both AC and DC. It makes it superbly easy to handle pressure problems no matter where you’re.


Cord Length


After checking the AC and DC compatibility, don’t forget to check the cord length. Remember, you will need to check the pressure of all tires. Another thing, the cord needs to be long enough to reach all the corners easily. Consider the position of your AC outlet and estimate if the cable will be enough for you. The best recommendation here would be a 10 foot plus cord.


Pump Time


The pump time is also something crucial to consider. You don’t need something that takes longer to get full. The faster the pump filling time, the faster you will solve the pressure problem. Some high-end tire inflators take less than five minutes. Try to get a model with something close to this.


What size air compressor do I need to fill car tires?

Filling car tires for most passenger cars requires taking the tire pressure up to 32 PSI or around 25 PSI during a cold day. A portable 1-2 cfm air compressor operating at 90 PSI can serve you quite well. However, if you’re planning are using a tire changing machine, you need to consider a four cfm model and above.

How many tires will a 5-gallon air tank fill?

Theoretically, a 10-gallon tank at 90 PSI can fill around four tires from 0 to 30 PSI if the tire’s volume is anything than 5.83 gallons. Now considering this scenario, a 5-gallon air tank can fill the same tires from 20 to 35 PSI only. If you’re reloading the tires from 0 psi to 30 or 35 psi, a 5-gallon air tank is tall small for the job.

How big of a compressor do I need to spray texture?

When it comes to spray texture, there is no one-size-fits-all. That’s why you have a regulator on the air compressor. A 1-2 cfm at 90 PSI is ideal as you may need 70 PSI for a start and test it till you get the result you need. Adjust the pressure finely down to as low as possible considering the type of material you’re spraying and level the coating.

Why are air tools better than electric?

Most people prefer air tools against electric because the high power-to-weight ratio contributes to less operator fatigue. What’s more, air tools do run cooler without generating heat. The same tools are quite flexible so that they can operate where electricity cannot, and they can handle a variety of tasks most electric cannot.

Air tools are also considered to provide low-cost maintenance and operation thanks to their fewer moving parts and the simple design. You should even know that there is some safety assurance with air tools; you don’t have to worry about electric shock and fire hazards.
