Costco Membership Perk: Free Nitrogen Tire Filling Stations

The new digital tire inflators are pretty easy to fiill your tires to within +/- 0.5 psi. I bought one a couple of years ago because I air my tires at home and my Volvo calls for 41 psi front and 42 psi rear. They’re 235 & 255/40s on 20" wheels so there’s not much air volume.
