When you reach the top end of the duty cycle you will have to pause inflation, let the motor cool off and then finish off the job later. For example, if a duty cycle is 25% then it can run for 15 minutes. The percentage is the amount of an hour you can run the compressor. The duty cycle can be a bit of a confusing figure as it is often listed as a percentage. If you are not patient, upgrading in this category might be the best option. These numbers will end up determining how fast you can inflate your tires. 1 CFM = 28.31 l/min, so the difference between the two is a matter of conversion. For example, 3 CFM means 3 cubic feet of air is flowing per minute. It is measuring the volume of air a compressor can generate in a given time. Maximum airflow is measured in cubic feet per minute (CFM) and on occasion, you will also see liters per minute (l/min). In the case of an air compressor, it is the amount of pressure that it delivers. Pounds per square inch (PSI) is the number you are probably most familiar with. In that case, you can get away with a smaller and more budget-friendly unit. For example, you may have already decided that you will never be upgrading your tires larger than 33 inches.

The tire size and inflating time are the factors that you want to have top of mind when looking for a portable inflator. Though you could go to a gas station and use their air, this is not a very savvy or reliable solution, especially in the case of a tire emergency. Once the adventure is over, you will need to inflate your tires to their recommended PSI to return safely to the highway and keep your car from getting damaged. While airing down will improve your performance off-road, driving on the pavement is obviously a different story. It also lowers your chance of blowing a tire while navigating rocky trails. Although your tire pressure sensors may light up your dash, airing down this gives the rubber more traction on challenging terrain by increasing the surface area in contact with the ground at any given time. When prepping your gear for off-roading, airing down your tires becomes essential. Low tire pressure is not necessarily a bad sign, it could simply be an indicator that it is cold outside and the temperature is affecting the air density inside the tire. Modern cars have tire pressure indicators, making the checking step easy, so you will want to make sure your tires stay at the manufacturer's recommended PSI.
