How To Inflate RV Tires The Easy Way (Hint: Use a Viair 400P RV )

NOTE: If you want one of these awesome Viair 400P-RV air compressors for your rig, you can find it here on Amazon:

We’ve changed the way we add air to our RV's tires. Before, we used our diesel pusher's on-board air compressor, but this new way applies to any type of RV, so this tip isn’t just for owners of large motorhomes.

If you've seen our previous videos about adding air to high-pressure RV tires, you know that using the on-board compressor isn't as simple as it sounds. Besides the problem of the pressure cycling up and down below our required tire pressures as part of its normal operation, we also try to avoid idling our engine more than absolutely needed. We hate being an annoying neighbor by polluting a campground with diesel exhaust and noise just because our tires happen to need air. Our new solution makes us a better neighbor.

If you've seen very many of our videos, you know that we’re all about finding money-saving ways to solve RV issues, but sometimes a top-of-the-line solution is the best solution, and you get what you pay for.

We discovered Viair, a manufacturer of ruggedized portable compressors, designed to handle more demanding situations, like filling large off-road vehicle tires. We like the fact that they make a model specifically designed for RVers, which got stellar reviews on Amazon, so of course that’s the one we ordered.
