Tire Deflator, 6-30 PSI Air Down Tire Deflators Offroad Accessories for Jeep, Car, Truck, Motorcycle, and ATV (4 Pack with Storage Bag)

They work well and are adjustable. They take time to adjust to desired pressure, but once set it is super convenient. They take almost 15 minutes to deflate from 39 psi to 17 psi.

I purchased these for my 2012 Jeep Wrangler because I drive on the beach fairly often when I get a chance. It took a little bit of playing to get them set to about 16-18psi, but now that I set them and locked the setting, it seems to work great. There is a slight variance in the psi for each, but that is due to how it works with a screw and spring. I think it’s perfect for my use since it is just out on each tire at the same time and I don’t have to stand by each tire one at a time and air down. I don’t mind if they are off by 1-2 psi for that, and even if it was an issue, I can dial it in with a tire gauge at the end and still save a lot of time. It only takes a few minutes and I’m ready to play/drive in the sand!! I added some silicon lub spray that I had, just to make sure it will last, but I’m not sure that is needed.

I got these a about a year ago and have used them a handful of times. Once you set them they're easy to use. The only problem is, as the pressure gets lower they get much slower which I guess is only natural. I've found them to be reasonably accurate but not enough for me to forego using a reliable gauge on the tires. I suppose I'll do what others have mentioned which is put them on and go ahead and drive a little bit. That would really work well on vehicles that will display the tire pressure on the dash but unfortunately mine doesn't do that. I do recommend these as a cheap way to air down. Just understand that you will have to be patient.

Works as it should

Work great

Got these on a whim for faster air-downs. My gauge is more accurate and so much faster. These take forever and also seem to get stuck, needs a knock to keep airing down and still doesn't seem to be accurate after checking.

We need to air down six tires on an RV to drive on a beach sand road. Using these makes the task faster and much easier. They are easy to use and do a great job.

These things save you time when you’re offloading they’re perfect you preset them you hook them up and you let it go and then when it gets to it needs to be on your air pressure then you put them back and go have fun when you’re done. are you charged back up?

No storage bag included as mentioned in the description. Item received in small carton that's it.

Looks like good quality haven’t test them yet fast delivery thanks

Work great, really saves time airing down

it works fine, easy to set and yes it takes 4 min to deflate (time will vary according to your size and desired deflation) but i think it made deflation easier.
