Tamiya 15444 JR Large Diameter One-Way Wheel Set - precision handling pack  [15444]

Product brief for Tamiya 15444 JR Large Diameter 1-Way Wheel Set

The Tamiya 15444 JR Large Diameter 1-Way Wheel Set is intended to enhance cornering control on Mini 4WD cars, notably those based on Super X and XX chassis. It is aimed at hobbyists seeking steadier, more predictable handling on technical circuits.

Construction details and compatibility

This kit contains black 1-way wheel parts that help reduce lateral friction when turning. Large-diameter black offset tread tyres are supplied to give extra traction and steadiness. While primarily designed for Super X and XX chassis, they can be fitted to other chassis with spacers and 72mm shafts, which are sold separately.

Handling improvements on track

The one-way mechanism lowers cornering resistance, enabling smoother power transfer and better speed retention through bends. It is a practical upgrade for competitive racing where precise line holding is important.
