Tamiya 15504 GP504 Super X/XX Large-diameter 5-Spoke Wheels with Hard Slick Tires (Red)  [15504]

Wheel Set Summary

The Tamiya 15504 set pairs large-diameter 5-spoke wheels with hard red slick tires, optimized for use on Super X and Super XX chassis. These parts are aimed at improving straight-line speed and overall stability on Mini 4WD circuits.

Fitment Notes

These wheels mount to Tamiya Super X and Super XX chassis without major changes for most builds. In some cases racers will trim or adjust body mounts to create enough clearance for the larger diameter wheels.

Track Performance

Hard slick tires reduce rolling resistance and work best on smooth, high-speed tracks where grip is consistent. The larger wheel diameter helps raise top speed, useful for tracks with long straights and timing-critical sections.

Upgrade and Tuning

Although built for Super X/XX platforms, these wheels are commonly used alongside motor, gear and damper upgrades to tailor handling and speed for specific track layouts and race conditions.
