To air my tires down, I use an ARB E-Z Deflator that I’ve had for a number of years now. I like using it because it is quick and the gauge has been accurate. It screws onto the valve stem and then you unscrew the valve core and move the slide to let air out. It is a little cumbersome for the first few uses but it gets easier to use as you go.

When you come to the end of the day, you will need to air your tires back up to street pressure before hitting the highway. There are a lot of different methods to air a tire up and since we have relatively small tires, any of the methods work great! I have a Milwuakee cordless air compressor that I use and it works really well; you enter the tire pressure you want and then hit start, it will turn off automatically when that pressure is reached so you can socialize freely. There are also 12 volt options that you clip onto your battery and air up that way, the 12 volt compressors that plug into the cigarette lighter work in a pinch but are not up to airing up all 4 tires. The last option is a bike pump. These actually work pretty well but you will need some endurance as it took 55 pumps per tire to get our 215/75-15s to street pressure from 15psi.
