B-G Racing - 4 Inch Tyre Pressure Gauge - 0-60 PSI / 0-4 BAR

B-G Racing 4" Analogue Tyre Pressure Gauge (BGR517) — a professional motorsport tyre pressure gauge with a large 4" dial for fast, easy reading at the car. Supplied by Harris Race Radios, an authorised B-G Racing supplier for New Zealand and Australia, listed on the official B-G Racing dealer network. All products are genuine B-G Racing hardware sourced directly from the manufacturer — not grey imports.

The 4" gauge is the preferred choice for professional pit lane and paddock use — the larger dial is significantly easier to read quickly under pressure, in poor light, or when wearing gloves. We work directly with racers, track day drivers, and teams across NZ and Australia to supply B-G Racing equipment that performs in real conditions.

Frequently Asked Questions

Why choose a 4" gauge over a 2.5" gauge?
The larger 4" dial is significantly easier to read quickly — especially in pit lane conditions, poor light, or when wearing gloves. For team use or professional pit crew applications, the 4" gauge reduces the chance of misreading pressure under time pressure.
