I'm running 35s on 17s. Was at Rausch Creek last weekend, aired down to 15 psi from 28 psi, air up took approx 15 minutes.
Here is the link to Wood's "Viair 400H ( 400C) torture test - Small compressor > Big results".

On the tire fill testing the compressor filled four 37" tires from 9 PSI to 27 PSI in 16 minutes.
What have we learned from all this? First of all, we know that this is only a 33% duty cycle compressor. But two and a half hours at 30 PSI, that's friggin great. For filling tires, the 400C and 400H represent what I believe is by far the best value for compressor based onboard air systems.
