The iCheckTPMS Automatic Tyre Deflators allows the user to simply screw them on and walk away. This saves time and your knees from having to arduously kneel down and deflate one tyre at a time.
“The iCheck tyre deflators appear to be good quality, super easy to set at required pressure with the etched/white markings.
However, set them to 20psi and put them on all four valves. One of them stopped within 30sec, the other 3 took about 2min or so. One seems to be faulty, always stops at around 30psi irrelevant of setting. Even set it to 10psi, still stopped at 30. Pulled the little tip out, but it goes straight back in.
The other pressures varied. As I said, set them to 20psi, one stopped on 20.5 one on 21.6 and the third was 19psi.
So not exact, but close. Might have to set them a bit higher then let them down manually to desired psi. Which defeats the purpose of tyre deflators.”
“Used them last 4wd trip away . Was so good to lower pressures all at same time while you have a beer :) didn’t take long and pressures are soooo accurate:)”
