Big Tyre is developing a non-pneumatic, non-solid wheel which combines excellent load, suspension and torque capacities with low ground pressure and good ride comfort.

Big Tyre is developing non-pneumatic, non-solid wheels for heavy equipment in association with, and significant financial support from, the Australia Coal Association Research Projects (ACARP).

Our aim is to develop wheels which are:

  • Puncture proof (airless)
  • Excessively strong
  • Comfortable
  • Resilient to impact
  • Efficient (even pressure & good tread utilisation)
  • Safe
  • Suitable for tough environments like mining and military use

The wheels are designed to be fitted with waterproof sidewalls to protect the interior from water and stones.

We have completed 3 prototypes to date: 2 large wheels for heavy machinery and a small wheel for a go-kart as a proof of concept.
