Adjustable Tire Deflator Auto-Stop (10-40 PSI) Offroad Accessories Valve Stem kit 4x4 Tyre Air Down Tool for Truck, Pickup, Motorcycle,Jeep etc.(Black)

These deflators actually have settings for PSI to set them to for your desired deflate level. Previously, I had another set of deflators from another manufacturer, and those were problematic. These deflators were exceptionally accurate. For only a few more bucks, are well worth the money spent. They come with a pouch and are easy to tuck into your glove box for storage. They appear to be made of quality materials, and I expect them to last me for a long time of off-roading.

Purchased these for a recent trip where I was needing to air down tires. The main reason was the price. They are very easy to use and functional. Just dialed in the pressure I wanted to start with. Took the tire pressure to exactly what was dialed in. All store up in a nice padded zippered pouch. Great quality and would buy again!

Great product! Makes airing down for the back country trails fast and precise. Carrying case makes it easy to store in your door. Definitely recommend!

I’ll preface this by saying that I bought these deflators to streamline part of my job - I process new cars at my dealership, and part of that is deflating tires to the specified pressure per car. These cars arrive with 45-60psi in the tires. Most of these types of deflators max out at 30psi, but the Dornatas max showing 40psi make them ideal. Almost all of the cars I do need tires set to 36psi, 35psi, 34psi, or 29psi - so my intention was to use the set of 4 individually, preset to these pressures. I can then get one tire going, work on another task, switch the deflator to the next tire, so on.But in my few days of using these, I’ve found that I can get 1 to 2 tires done before the cooling effect of the air decompressing through the deflator has raised its valve-closing pressure above what I have it set to. Last week, they worked pretty well, only minor adjustments on the last tire or two per car when checking with a gauge. Today, it’s around freezing outside and wheels/tires/air in them is cold - I can get 1 tire done and by the next, my 36psi-set deflator gives up at 45psi or won’t open at all, and needs to be warmed up before it functions correctly again. Once warm, it’s pretty accurate!Maybe these will work right in higher temperatures, but they’re not ideal for repeated use in cold conditions. Unfortunate!

Starting at 5 stars based on quality of product before use. The packaging was nice, the pouch that holds the deflators is well made, sturdy and secure. Instructions are clear and concise.The deflators have a solid, heavy feel to them. The threading on the PSI indicator tube moves smoothly and with no play or slop. The plunger and spring feel well built and sturdy. I have not had the opportunity to test them on my Expedition Vehicle as of yet. I have performed a few tests on a bicycle tire and the accuracy is spot on when deflating. I will report back once I've used them on the truck.

These were slightly off by a few PSI but otherwise they worked great for airing down my Tacoma!

Works but a pain to set all 4 the same

Saw these last year for over $100 These were somewhere around $20. Great ! Worked perfect ! Highly recommended
