Update: We’re having trouble with this code, but will update the post if we figure it out.
Forget trying to find quarters under your car seat and paying way too much for 3 minutes of air, and get this $22 tire inflator with code 975WIE8H. You can fill up your tires whenever and wherever you please for free. Keeping your tires properly inflated helps improve gas mileage so this guy will basically pay for itself. It also works on bike tires.
