Best On Board Air Compressor for The Jeep Wrangler

Airing down your tires is part of the Jeep Wrangler game if you want a smoother ride and you want a little more traction.  But after the trail you need something to assist you in filling them back up.  That’s where the on board air compressor comes into play. 

After the trail, when you are ready to get back on the highway you need to air back up so that you can go the speed limit and get home safely.  Using cheap air compressors from box stores may have worked when you were driving a Ford Fiesta but they aren’t going to work for your big Jeep Wrangler tires.

Cons Explained

  • While this system is not the most expensive of options it does require the most space in your Wrangler.  As we all know the Wrangler is lacking in terms of space and the 33 inch long and 12.5 inch high air tank will take up a lot of your space in the cargo area of the Wrangler.  We have seen tanks installed underneath the vehicle but we are not quite sure that is the best location for something under so much pressure while you are offroading.

Frequently Asked Questions

What Is An On Board Air Compressor?

An on board air compressor is a compressor that is installed to fit onto your rig for its lifetime.  Typically, once installed it’s not going to come out unless you want to spend the time to uninstall and install the system which could take a very long time.

Differences Between On Board Air Compressor And Portable Air Compressors

On board air compressors differ from portable air compressors first by their lack of portability.  Portables can easily be swapped from vehicle to vehicle and there is little setup time.  In terms of capacity, the on board systems will typically outperform the portable systems because they are larger and built to perform. 

This performance by the on board air compressors does come with a price tag, but typically you are going to have your on board air compressor last longer. 

Portable air compressors tend to not be able to work continuously without burning up their engine after a couple of years as these machines run very hot while trying to get air to your large tires.

Another major difference about on board systems is that it comes with an air tank.  This air tank helps regulate the flow of air and does not put so much pressure on the compressor’s engine.  Tire fill up time is reduced as well.  Imagine doing a week full of trail days.  Filling up all four tires in under 8 minutes compared to 20+ minutes could be a game-changer for those that can afford the convenience.
