Review on Teraflex 4807200 Air Deflator by Hikeboy Ramey

My tires are not very big (235/75r16) but they are great for airing at the beach. I usually keep tire pressures between 37 and 40 psi. Put one on and then walk around the car. When I finished mounting all four, the first tire had about 20. I checked the other tires and got them all to 19-20psi using this method. It's a very good alternative to sitting down and sticking the key in the valve, and it's a lot cheaper than Trailhead's or Staun's psi-adjusted deflators.
