Staun Tire Deflators (Airdown to 15-55 PSI) Heavy Duty

A high quality product with outstanding customer support. Every business could learn something from their customer care team. Deflators work perfectly and are made of high quality materials. We used them many times when we went off road on our 2026 15k road trip from VA to AK.

I purchased this product because tires on new vehicles are overinflated from the factory to prevent creating a hard spot during transport, and must be aired-down before delivering to customers. I have these set at 40psi while factory tires are 50-60 psi. So far, they generally go between 39-41 psi which it well within expectations. I check every tire with the display on the instrument panel. So far I have done several hundred vehicles without a single major error. They typically deflate a 33" tire from 60psi to 40psi in about 40 seconds, which means by the time the last one is installed, the first one is ready to go. The speed is unbelievable for the accuracy I am getting. I cannot speak as to how great they are for off-roading, but I expect this to work great. I recommend getting the speed chuck adapters from Skog if you intend to use these regularly.

So far, these have done their job just fine and deflation has been pretty consistent +/- 1 psi. The small, compact size makes them great for glove box storage.

I bought these because of the reviews, I have set these three time, I aired down the spare on my JK to 15 psi watched several videos screw them on until you hear air the lock them down, first trip up Agentine pass aired down checked the pressure they stopped at 20 psi, got back home aired down the spare to 14 psi made a second trip still stopped at 20 psi tried a third time again aired down the spare to 13 psi trip to Ouray aired down stopped at 20 psi it should be that hard to get these dialed in my friends EZ Deflators spot on at 15 psi.

They arrived promptly and are the worlds best tyre deflation system. Set them up as per instructions and they are very quick and convenient, and automatic, to use when deflating tyres on a 4wd track. Other Deflators work, but typically don’t deflate rapidly when approaching the set pressure, and don’t positively click off when at set pressure, just sit there with a slow leak going on. Staun Deflators rapidly let the tyres down and then positively click off at the set pressure. If you want faster deflation of larger tyres, buy this heavy duty unit with two holes in the unit - the single hole units take a bit longer for 35” tyres, but all units work better than advertised. In this day and age full of dysfunctional imitation products, that’s a great thing, well done Staun
