Question:

Hello, Is this EVC23P Viair EVC Portable Tire Inflator - Item VA88JR strong enough and durable enough to maintain my six RV tires size 235/80R/22.5 at 90 to 94 psi? I would check them when cool from time to time, occasionally while on the road, and might need to add a few psi to each tire. Thanks, Bruce

Hello Bruce, thanks for reaching out. The Viair EVC Portable Tire Inflator # VA88JR will absolutely work for maintaining the PSI in your 235/80R/22.5 tires. The compressor can go up to 120 PSI so 90 to 94 PSI will be just fine. It can be a little slow when getting up to higher PSI but it will allow you to top off your tires whenever needed. You just want to make sure you don't let it run for too long at once or it will overheat and shut off.
