Uharbour Adjustable Tire Deflator, 10-30 Psi Tire Deflators Offroad Accessories, Auto Stop Air Down Tire Deflators, Air Down All Four Tires(4 Pcs)

These tire deflators are easy to adjust, accurate, and fast. PSI is in increments of 5; I deflate my tires to 24 pounds, so I estimated the deflators at just under 25 PSI and 3 of them deflated my tires to 23.5 while the fourth was 25. I re-set the 4th one time and it deflated to 23.5. I inflated my tires back up to 30 PSI, then 24 hours later I put the deflators on and they dropped each tire to 23.5 PSI. Very, very nice. I've used other deflators but these are the best I've found regardless of price. These greatly reduce the time and the hassle of my off-road ritual. Love them!

Used these for the first time on a recent 4x4 trip to air down tires. I picked 20 pounds and adjusted all to that setting. I had two tires with 20 pounds, one tire at 17 and the other tire at 12. The adjustable spinners twist very freely, a little too freely. The vibrations from the air coming out wiggles the spinners so much that they did not stay where I wanted them to be. I might try wrapping tiny rubber bands at the poundage I want to see if that keeps the spinners from moving. Would not recommend these.

Works as advertised, if you drive on beach highly recommend

Small, but worked well

The screw adjuster loosened itself up and deflated the whole tire. The locking screw should be better

These are made out of brass & worked this past weekend airing down my tires to ride on the dunes in Cape Cod. They even come with a storage case. We'll see how well these will hold up. I'll follow up with updates if there are any changes. Overall I would highly recommend purchasing these Adjustable Tire Deflator, 10-30 Psi Tire Deflators Offroad Accessories, Auto Stop Air Down Tire Deflators, Air Down All Four Tires (4 Pcs) Finally this review is of my own honest opinion & is not swayed in anyway by other influences.

I set two for 15 PSI and two for 25 PSI and each one deflated to within .6 PSI below the setting. This is crazy accurate compared to the other deflators I've used. Typically I'll get within a couple pounds and within two or three attempts I get the pressure I want. These deflators nailed it the first time on all four units. I'm impressed. They look like they're built to last. The brass body, plunger, spring, and nylon seal all look like they're well made and made to last. I would buy these again even if they cost a bit more than the competition. The extra cost would be worth it to avoid the fuss of getting the whole set to a specific pressure. And these are reliable enough that I'm comfortable changing the pressure setting for another vehicle without spending ten minutes or more dialing them in. Highly recommended and a job well done to the manufacturer.

Worked ok, have to make sure jam nut is very tight or it will let all of the air out of your tire
