Analogue vs Digital — Which Tyre Gauge Should You Choose?

• Choose the 2.5" Analogue (BGR515) if you want a simple, battery-free gauge with proven reliability. Fast to read, no power required — ideal for quick tyre checks between sessions.
• Choose the 2.5" Digital (BGR516) if you want higher resolution (0.1 PSI) and a backlit display showing PSI, BAR, KPA, and kg/cm² — ideal for precise tyre pressure management in variable conditions.
• Choose the 4" Analogue (BGR517) if you want the largest, easiest-to-read dial — ideal for use in poor light or when reading quickly at the car.
• Not sure? Contact Aaron or Rex at Harris Race Radios for advice on the right gauge for your application.

Frequently Asked Questions

Why does tyre pressure accuracy matter in motorsport?
Even a 1 PSI difference in tyre pressure affects handling balance, tyre wear, and lap times. A quality, accurate gauge ensures your pressure readings are consistent and repeatable — so your setup data is reliable and your tyre management is effective.

Is this gauge suitable for both cars and karts?
Yes. The 0–60 PSI range covers both car and kart tyre pressures. For kart-specific tyre pressure management with temperature logging, also consider the Alfano Tyre Control range.

Is this a genuine B-G Racing product available in NZ?
Yes. Harris Race Radios is the official Australasian distributor for B-G Racing. All products are genuine B-G Racing hardware sourced directly from the manufacturer, with local NZ and AU stock and fast dispatch.
