How to Use a Portable Tire Inflator (Step by Step)

A portable tyre inflator is one of the most useful tools you can keep in your car. Correctly inflated tyres improve fuel economy, handling and safety. Here's how to use one in five easy steps.

Step 1: Find your correct PSI

Check the sticker inside your driver's door or your owner's manual for the recommended pressure. It's usually between 30 and 35 PSI for most cars.

Step 2: Set the target pressure

On a digital inflator like the Trendora AirPulse, enter your target PSI. The pump will stop automatically when it reaches it, so you can't over-inflate.

Step 3: Connect and inflate

Unscrew the valve cap, screw on the hose, and press start. A quality cordless inflator fills a standard car tyre in a few minutes.

Step 4: Check and repeat

Do all four tyres, then screw the caps back on. Check when tyres are cold for the most accurate reading.

A cordless, rechargeable inflator with auto-stop makes this effortless — no cables, no petrol-station queues. The Trendora AirPulse also inflates bikes, sports balls and inflatables with its included nozzles.
