H&R Racing rear wheel and tire assemblies with 27 x 21 mm Fish Rubber foam tires and set-screw mounting for 1/8" axles.

These H&R Racing Fish Rubber rear wheels and tires are designed for slot cars using a standard 1/8" (3.2 mm) rear axle.

The mounted Fish Rubber foam tires measure approximately 27 mm in diameter by 21 mm wide, providing a wide rear contact patch for hardbody and performance-oriented 1/24 scale builds.

Key Features

• Fish Rubber Foam Tires – H&R Racing's foam rear tire compound
• 27 mm Diameter
• 21 mm Width
• 1/8" / 3.2 mm Axle Fit
• Set-Screw Retention – Secure mounting to the rear axle
• Mounted Wheel & Tire Assembly – Ready for installation and final setup
• Designed for Rear-Axle Use

Wide Rear Tire for Hardbody Builds

The 21 mm-wide rear tire provides a substantial contact area and is well suited to heavier hardbody slot cars where rear traction and stability are important.

The 27 mm overall diameter also makes these assemblies useful for many traditional 1/24 scale chassis and model-body combinations.

Set-Screw Mounting

The wheel is secured to the axle with a set screw, making installation, removal and gear-side adjustment straightforward.

This allows the rear track width and wheel position to be adjusted during chassis setup rather than permanently fixing the wheel to the axle.

Axle Compatibility

These wheels are designed for 1/8" axles, equivalent to approximately 3.2 mm.

Always confirm your axle diameter before ordering, as 3/32", 2.38 mm and 3 mm slot car axles are not the same size.

Jim's Racer Perspective

For 1/24 hardbody cars, a wide rear tire and a securely mounted wheel make chassis setup much easier.

I particularly like set-screw wheels because rear track width, gear alignment and wheel position can all be adjusted during setup instead of being permanently committed.
