What is a Tread void?

A tread void in basic terms is the gap between the tread blocks.

Whats the benefit of the void?

The void provides space for the tread to flex and deform as it enters and exits the tyres road contact area. Voids also provide channels for rainwater, mud, and snow to be channeled away from the footprint.

What is void ratio?

The void ratio is the void area of the tyre divided by the entire tread area.

What does low void ratio mean and what are its benefits?

Low void areas have high contact area and therefore higher traction on clean, dry roads.

What does High void ratio mean and what are its benefits?

High void areas have a low contact area and therefore better at water clearance which will reduce the chance of aquaplaning.
