what are the best big wheels for a mousetrap car

[McRicardo]

The best large wheels for a mousetrap car are lightweight materials like corrugated plastic or foam board, which can be cut into circles. Some builders do repurpose unwanted LPs with added rubber edges for traction. For performance, aim for low rotational inertia and good grip, foam wheels or rubber-wrapped rims work well. For distance races, 11-inch corrugated plastic wheels are ideal.
