Aluminium wheel 16.5x10mm. Lightweight for Axles 2.38mm with M2.5 Screw Weight 1.10 g.

Precision and lightness at the service of your slot assembly with the Lightweight aluminium wheel from Scaleauto

Scaleauto is one of the leading brands in competitive slot racing, and its Lightweight aluminium wheel line is a good example of why. Machined with precision criteria, these wheels are designed for enthusiasts who pay attention to every tenth of a gram in the assembly of their 1/32 scale cars.

Function and performance

The Lightweight aluminium wheel SC-4054F25 has dimensions of 16.5 x 10 mm and is designed to fit 2.38 mm diameter axles, ensuring a firm and snug fit. The attachment is made using an M2.5 screw, which facilitates disassembly and readjustment during car preparation or tuning.

Its main advantage is the weight: 1.10 g per unit. In a slot car, reducing the mass of the rolling elements —wheels and rims— has a direct effect on acceleration and cornering response, as it decreases rotational inertia. This detail makes a difference in configurations aimed at competition or improving overall track performance.

Compatibility and assembly

This wheel is designed for 2.38 mm axles, a common measurement in 1/32 slot setups aimed at preparation. Before mounting, it is advisable to verify that the axle diameter of your car matches this specification to ensure a correct fit and avoid vibrations or eccentricities that could affect rolling.

The included M2.5 screw allows for secure attachment without the need for adhesives, facilitating maintenance and tyre changes during a track session or between heats in a championship.

Common mistakes when choosing aluminium wheels

• Not checking the axle diameter: mounting a wheel on an axle of a different size creates play or may damage both the wheel and the axle. Always check that your axle measures 2.38 mm.
• Confusing width and diameter: the measurements 16.5 x 10 mm indicate diameter x width. Ensure that the tyre you are going to mount is compatible with that wheel width.
• Over-tightening the M2.5 screw: aluminium is a material that can deform if too much torque is applied. A firm but moderate adjustment is sufficient.

Frequently asked questions

What scale is this wheel designed for?

It is designed for slot cars in scale 1/32, which is the most widespread scale in club competition and advanced recreational use.

How many wheels does the product include?

The available information corresponds to the individual reference SC-4054F25. We recommend checking the store listing to confirm whether it is sold in units or packs.

Is it compatible with any 1/32 tyre?

The tyre must be compatible with a wheel width of 10 mm and a diameter of 16.5 mm. Not all 1/32 tyres have the same measurements, so check the tyre specifications before combining it with this wheel.

Why is the weight of the wheel important in slot racing?

In a slot car, the mass of the rotating elements —wheels, rims, and axles— directly influences rotational inertia. Reducing it improves acceleration response and corner transition, something particularly noticeable on technical tracks with many direction changes.

Can it be used on Scalextric or Ninco track cars?

The wheel itself is a mechanical component that does not depend on the type of track, but on the diameter of the car's axle. If the car uses 2.38 mm axles, the wheel can be compatible regardless of whether the car runs on universal track (Scalextric, Ninco) or Sport track (Scaleauto, Slot.it).

Do I need special tools for assembly?

A suitable screwdriver or wrench for the M2.5 screw is sufficient. No specialized tools are required, although having a centering tool can help ensure a perfectly concentric installation.
