Frequently Asked Questions
Why does tread depth matter in motorsport?
In wet weather racing, tread depth directly affects water evacuation and grip. In endurance racing, monitoring tread depth across a stint helps predict tyre change windows and avoid unexpected failures. Even in dry racing, worn tyres behave differently — knowing your tread depth helps you make better strategy decisions.
Does this gauge read in both mm and inches?
Yes — the B-G Racing Digital Tyre Tread Depth Gauge reads in both metric (mm) and imperial (inches) units.
Is this available in NZ and Australia?
Yes. Harris Race Radios is the official Australasian distributor for B-G Racing, with stock available for fast dispatch to customers across New Zealand and Australia via NZC and DHL Express.
