Tire Deflator Kit Universal Adjustable Pack of 4

ما اعجبني وصعب شوي. وحدة من الاربع مختلفة بالحركة

After using these for a while, I have come to the conclusion that pre-setting PSI is a waste of time. As you get closer to the pre-set air comes out more slowly and I couldn't get the preset exactly where I wanted and i nay case I may change from 20-15 depending on the trail. Instead I use the wide open, know from experience how long they take and then check and do the last few PSI manually. This is quick, just a few mins to get from 40 down to 18 on 33x12.5 tires. I would use expensive ones the same way. These are solid and never had an issue after years of use. The metal container is nice too.

I adjusted each valve to stop releasing air at about 20 psi then fine tuned the higher ones down so they were about the same. I timed 10 minutes to go from 34 psi (35x12.5x17 tires) to about 20 psi. Don't have to monitor and I can do other things/ No problems.

Nice device. It was easy to set all 4 valves, and now my time to deflate at the beach is much reduced. The valve took the pressure down the amount I set.

Great idea to plug and play and save time.
