Review on Teraflex 4807200 Air Deflator by Jonathan Wilson

I do a lot of off-road riding and lower the pressure from about 35psi to 15psi for sand and about 20-25psi for rocky roads. This is great and makes it easy to air all four tires at the same time. He's very fast, so I have to keep a close eye on him so I don't go too deep. The coolest thing is that it's easy to attach a pressure gauge to check PSI without taking them off. It's a really cool, inexpensive, and handy tool for us SUVs.
