The Rapid Tire Deflator Kit is a budget set of four automatic deflators from an unbranded seller. You set them to a pressure between 10 and 30 PSI, screw them on, and they stop when the tyres get there. They weigh 160 g and cost me $29. They work, but the accuracy and the case are what you’d expect for the price.
What’s in the box
Four stainless steel deflators with knurled grips, adjustable from 10 to 30 PSI with a quoted accuracy of ±2 PSI, in a small carry case.

- Cheapest automatic set

Setting them
Twist the housing until the stop lines up with your pressure on the markings, then lock it. The markings are clear and the knurled grip works with dusty fingers. Check the first tyre with a pressure gauge, because the scale only gets you within a couple of PSI.
On the tyres
Screw them on and they let air out steadily, then stop at the set pressure, so you can start on camp instead of crouching at each wheel. With the ±2 PSI tolerance, ours landed close enough that we rarely needed to adjust, but the four tyres won’t always match exactly. For towing or technical driving where the exact pressure matters, check with a gauge afterwards.
Build and case
The stainless steel deflators feel solid enough and resist rust if you rinse and dry them after sandy or muddy trips. The case is the weak part: it’s basic and doesn’t feel like it will last as long as the deflators. At 160 g the kit is easy to keep in the glovebox.
How it compares
For more money, the KickAss set ($50) is easier to set and more consistent, and the CampBoss Boss Air set is our top pick. Our tyre deflators guide compares them all.
Conclusion: Automatic Rapid Tire Deflator SetConclusion
The Rapid Tire Deflator Kit is the cheapest way into automatic deflators: four stainless steel deflators, 10 to 30 PSI, 160 g, that do the job of airing down while you do something else. Accuracy is ±2 PSI, the case is basic and it’s from an unknown brand. I paid $29; for occasional sand trips it works, but a branded set is worth the extra if you air down often.
The cheapest way into automatic deflators, and fine for occasional sand trips.
The four stainless steel deflators air down from 10 to 30 PSI while you do something else, and landed close enough to the set pressure for most trips. Accuracy is ±2 PSI, the case is basic and the brand is unknown.

- Campers
- Beach & picnics
For occasional use, yes: I paid $29. If you air down often, the KickAss set at $50 is easier to set and more consistent.
