Will I only be using the compressor for the car or also for bikes, toys, balls etc.?

(Consider the number of adapters and the strength of the unit which you need.)

Will it always be kept in my car or will I also use it at home?

(Consider buying a compressor with a specific option for both an AC and a DC connection.)

Are these features important to me: Automatic shut-off, emergency LED light and a digital display?

(Choose the digital compressor.)

Do I find an analog display easier to read, and I need more PSI?

(Choose the analog compressor.)

Is the air flow rate important to me?

(Consider: The digital compressor gives 30 liters per minute. The analog compressor  gives 20 liters per minute when connected to a home wall socket, and 18 liters per minute when connected to your car.)

Is the weight of the compressor important to me?

(The digital compressor is 5lbs and the analog compressor  is 3.3lbs.)

Is measure accuracy important to me?

(Digital compressor : +- 1PSI. Analog compressor : +- 3PSI)

The PSI is usually printed on a sticker that is located on the top of the door frame on the driver’s side of the car. This is the recommendation of the car manufacturer. On some vehicles, the sticker is found on the trunk door or on the fuel door. If your vehicle lacks this information the correct tire pressure should be found in your car’s user manual.

Most cars will recommend between 32 and 35 PSI.

Warning! Do not pay attention to the PSI displayed on the tire walls which sometimes display the maximum tire pressure and not the pressure recommended for your vehicle. Too much pressure can ruin the tire.

You need to inflate your tires once a month because they lose 1 PSI each month. You should also check if there is a puncture that has caused a loss of air.

Also, when the air temperature changes 10 degrees Fahrenheit, tire pressure will change about 1 PSI so it is worthwhile to replenish your tires’ pressure. (A rise in temperature raises the PSI and a drop in temperature lowers PSI.)

Remember: When your wheels are inflated to their recommended pressure you will benefit from their optimal lifespan and performance.
