I have always just used a stick or key in the past which has been quick and easy. 1 minute as a rule of thumb from road pressure, I normally run 34-36psi and this normally puts me around 18-20psi. The downside of this method is it runs the risk of over deflating the tire from the desired pressure.
I recently purchased a tire deflator from ARB and it was so slow (5 min per tire). After the first tire I reverted back to my previous method and just checked the pressure once they were deflated. Is there something wrong with my tire deflator or is it normal for them to be this slow?
I'm interested in how others deflate there tires i.e. stick into valve, tire deflator, pre-set pressure deflators?
