Rv Tire Inflators

[Joe0711]

Am in process of outfitting our new Precept 35UP and will buy a portable compressor for inflating tires. The Bosslady has found a Viair 400 12vdc that has gotten good reviews and promises to do the job for around $250. Because I am an old construction guy, I am in favor of a smaller electric 120vac pancake compressor to do the job faster and spend a hell of a lot less $. I know the performance, weight and cost differences, but am really interested in what y'all use.

Welcome to the forum and congrats on the new Jayco. We have a Viair portable compressor. Model #88P. It connects directly to the battery and works perfect for our needs with the TT and TV. It is currently on Amazon for $62.41. Have fun camping and Happy New Year!

I have this one and it works great, up to 100psi.

I did have to purchase two 12v 10' extensions to reach the tires from the truck when its hitched. One was a few feet short. When one is connected and the truck is running it works well. When both are connected the compressor struggles due to loss of voltage, but it still gets the job done. I'll only use the second extension when I have to.

You need a compressor that will output more than 100 psi. Your dealing with truck tires, which generally range from 90 to 110 psi. They also have a much larger volume of air capacity than cars. Many times the rv manufacturers post the psi recommendation on the wall in the drivers area. This in my experience is usually too low. I increased our psi by 15 lbs due to our loading. Coach handled way better, and no significant decrease in ride quality. Precept 35un.

Built in viair and tank in tool box on truck now with qd in running board. On our Motorhomes I carried a portable porter cable comp and just plugged it in since we always ran the genset. The p/c had a quick recovery which was nice when airing up the 22.5 tires

Has anyone any experience with the "Air Dragon " inflators I have seen advertised on tv.
Kind of like the floating screen door ads?

I use a small electric pancake compressor that goes up to 125psi, So far so good, I have a 35UN

Thank you for your post. Because of y'alls comments and some prior knowledge I purchased an AC pancake compressor with a 125lb tank and and is capable of pressuring a tire up to 100lbs.

Maybe already known, but for best ride weigh 4 corners of Motorhome, or 4 tires then adjust tire pressures according to weight and michelin pressure vs weight charts. We always stuck to a compressor capable of 150 due to some of our tires on previous Motorhome requiring 110 psi if I remember right. We owned a 36' class A with the 22.5" tires on the F53 chassis.
