An advanced tool used by serious off-road enthusiasts, tire deflators come in various forms and each allows drivers to quickly and precisely deflate or ‘air-down’ their off-road tires when required for enhanced grip, traction, and adaptability in challenging terrain.

Though most motorists know that maintaining proper tire pressure is vital to safety performance and fuel efficiency, certain situations faced by off-road drivers require tires to be run at a low pressure, which makes the tires more flexible and grippy. With a tire deflator, drivers can quickly air down their tires to tackle a challenging obstacle or path, and then re-inflate later once the way is clear.

Tire inflators all do the same thing—but they work in various ways, and not all products are created equal. If you’re after a tire deflator kit, you’ve got numerous options at a wide range of price-points. Here’s a closer look.

1. Editor's Pick: ARB E-Z Deflator

For a few bucks more than the cheapest options listed here, the ARB E-Z Deflator features a stylish carrying pouch, solid construction, the backing of a well-known brand, and excellent owner reviews. With built-in corrosion resistance and special provisions for enhanced pressure-reading accuracy, even in varying temperatures, the ARB E-Z Deflator makes airing down your tires quick and exact. The fully-geared brass precision movement and 1-PSI increments provide a highly precise pressure reading in real time, too.

Just note that fully manual operation means you’ll need to watch the dial to stop the deflation process for each tire and that this product requires users to remove the valve core on each tire prior to use. This makes the deflation process faster. Owner reviews of the ARB E-Z Deflator are generally positive and point to satisfaction with the performance, ease of use, and quality for the price point.

2. Staun Automatic Tire Deflators

When you want to air your tires down quickly and easily, a set of Staun Automatic Tire Deflators might just be the ideal answer. The standard duty model is adjustable from 6 to 30 PSI, though the factory 18-psi preset is ideal for most applications. The Staun Automatic Tire Deflators are Australian-built with precision manufacturing by a brand with a strong reputation, and owner reviews reflect good quality, fitment and performance. A set includes four automatic deflators.

Staun Automatic Tire Deflators work in seconds to reduce the inflation pressure of the tires on your 4×4, thereby increasing their effective footprint and allowing improved navigation of softer and more challenging terrain. Whether handling rocks, sand, mud or snow, these deflators make airing down a total cinch.

Owner reviews are strongly positive, with over 98 percent falling into the 4 or 5-star range. Most users report satisfaction with spending a few extra dollars on this product compared to cheaper alternatives, in exchange for high quality and fuss-free operation.
