Air compressor for 115 psi

I went from 80psi tires to 125psi tires and my Porter Cable pancake compressor couldn't get past 108psi (and it was rated to 135). Enter the Viair 450P. It's expensive but 100% duty cycle so that I could air up all 4 RV tires and all 6 truck tires without having to think about how much I was using it.

I'd buy it again in a heartbeat.

I aired up one of the tires that picked up a nail at a service center from 80psi to 125psi pretty quickly. I was never bothered by the speed of it.
