I was talking to a guy who helped me air up after mcr9 and he told me it would normally last him all summer without recharging it. I have a york I was going to use but I decided to keep my ac. I have a 20g co2 tank with regulator here that is going to be mounted in my bed for next years wheelin season. I will say I was shocked how fast it aired up my 35s from 9-10 pounds to 35 psi.
