So, What Size Air Compressor Do I Need To Fill Car Tires?
The truth is that you can use any size air compressor to inflate your car tires. The best car air compressor for tires is going to be powerful enough to not take too long to air up your tires. The worst air compressors for inflating tires will take 20 minutes or more to air up a single tire.
If you get an air compressor that has a high CFM rating but also has a small air tank, you may be spending more time waiting for the air compressor to recharge its tank than the tire inflation process itself.
While it depends on what type of vehicle you have, as a general rule of thumb you need somewhere between 1 and 2 CFM (Cubic Feet per Minute). CFM is the volume of air that can be moved by the air compressor.
This is important to know because there are many air compressors out there, such as the ones powered by an electric cigarette lighter, that produce far less than 1 CFM.
You should avoid tankless air compressors. This is because the most efficient car air compressor uses a tank to store its pressurized air. So, as long as you find a relatively powerful unit that has a decent-sized storage tank you will be able to quickly inflate car tires, bicycle tires, or even truck tires.
Using An Air Compressor To Inflate Your Tires Will Save You Money
If you don’t believe us, then just take a look at fueleconomy.gov. The organization just happened to perform a recent study that showed just how much fuel economy you can lose by not keeping your tires properly inflated.
In fact, if your tires are under-inflated, you can expect 0.2% less gas mileage for every 1 PSI low your tires are.
That may sound small, but it adds up big time when it comes to miles per gallon over an extended period of time. Also, properly inflated tires have far superior traction characteristics compared to tires that are not full.
Another important factor to take into consideration is the fact that keeping your tires at the proper pressure extends their lifespan. This is because when your tires are under-inflated, there is an unnecessary amount of wear placed on certain parts.
As you may know, tires are not cheap. A complete set of new tires for most vehicles will cost about $400 dollars before installation. So, keeping your tires properly inflated will save you a ton of money in the long run because you will not have to buy new tires as often as you otherwise would have.
