Which Viair compressor are you looking at? There are several models with various specifications/capabilities.

[Crossfire8207]

Hi thank you for responding right now considering the
VIAIR Corporation - 400P-RV Automatic Portable Heavyweight Series Air Compressor

[CHICKDOE]

i have the rv400p and i use it to take my tire pressure up to 110psi. i think it has a duty cycle of something like 15 to 20 minutes and then it must cool off. there is a rv450p model which goes to the same pressure and has a continuous duty cycle. the rv400p works just fine for us.

You guy's are awesome on here thank you chickdoe for your response you have made my decision easier for purchase

Optimal tire pressure is whatever the manufacturer stamps on the sidewall of the tire in my opinion.

Thank you I wanted to know if you could tell me my class A is in storage and forgot what the pressure was?

Gotcha. I've known of people who think that is only a MAX on the side of the tire, and if they have less than a full load, perhaps they should deflate some.

Happy travels!!

[Crossfire8207]

Thank you, yes I agree less than max load unless loaded
Is that normally less then 95 correct?

There Load and Inflation Charts for MICHELIN RV Tires and also GOOD YEAR RV tires on line. they will guide you through the proper inflations.
Good luck and safe travels.

Here's a picture of the data sheet posted next to the drivers seat in my 2016 30DS. It specifically shows 82 PSI COLD.

Welcome to the forum!

We recently purchase the Viair 450P RV and love it. It's a little pricey but will last for generations.

Whatever air pump you get, it's a wise choice. Finding and getting access to air at fuel stops can be pretty difficult.

Thank you very much edm

My Viair 400 takes my Jeep tires from 15-18 psi back up to 33 like it’s nothing. It trips me out, it’s such a little machine. Haven’t used it on my FR3 yet, but I have no doubt it will do the job.

[Crossfire8207]

Wow you guys are awesome for the response on this topic, I bought the viar 400 the other day and tried it on my car tire and was fast. No doubt this was a great purchase and expect it to work fine on the rv thank you papaduck for the picture mine is in storage so I forgot what the preasure was really appreciate your feedback everyone. Think spring lol
