Aluminium Wheel 15.8x8.5mm. Lightweight for Axles 2.38mm

Scaleauto Lightweight Wheels: Machined Aluminium for 1/32 Slot Racing

Within Scaleauto's range of aluminium spare parts, the Lightweight wheels represent a clear commitment to reducing unsprung mass. Less weight in the wheel translates to a quicker response to acceleration, more efficient braking, and lower rotational inertia, all crucial factors when competing on Sport track layouts or mixed surfaces where car control is as important as engine power.

Features and Function

• Dimensions: 15.8 mm diameter x 8.5 mm width.
• Axle Compatibility: Designed for 2.38 mm axles, the most widely used standard in 1/32 slot racing setups.
• Material: Machined aluminium with a Lightweight finish, prioritising weight reduction compared to conventional aluminium wheels.
• Scale: 1/32.
• Reference: SC-4031F25.

Assembly and Preparation

Mounting on the 2.38 mm axle must be done with the proper fit to avoid play that could cause vibration or wobble during operation. It is recommended to check concentricity after assembly before installing the tyre, especially when working in racing configurations where the geometric precision of the wheel directly affects grip and cornering behaviour.

As a Lightweight wheel, its wall and material are optimised for the minimum possible weight. Therefore, it is advisable not to overtighten beyond what is necessary and to use appropriate fastening tools to avoid compromising the integrity of the machining.

Compatibility

This wheel is designed for mounting on 1/32 slot cars, being compatible with any setup that uses a 2.38 mm axle. Its diameter and width make it suitable for applications on both rear and front axles, depending on the car configuration and the chosen tyre profile. Always check your chassis measurements to confirm compatibility before mounting.

Who is it for?

This wheel is aimed at tuners and club racers looking to reduce the rotational inertia of their wheels for improved agility and response. It also suits enthusiasts preparing 1/32 slot cars for championships where regulations allow modifications to the running gear and every tuning detail makes a difference.

Common Mistakes

• Mounting the wheel on an axle with a different measurement than 2.38 mm: this can cause play or inability to adjust.
• Not checking concentricity after assembly, leading to vibration and loss of performance on track.
• Combining Lightweight wheels with tyres of incompatible profile or width with the dimensions 15.8x8.5 mm.

Frequently Asked Questions

What axle size is this wheel designed for?

It is specifically designed for 2.38 mm axles, the usual standard in 1/32 slot racing setups.

What advantage does the Lightweight version offer over a standard aluminium wheel?

The Lightweight version has less mass, which reduces the rotational inertia of the wheel. This results in better throttle response and more precise braking, particularly noticeable on technical circuits with many speed variations.

Is it suitable for both front and rear axles?

Its dimensions (15.8x8.5 mm) make it suitable for both positions, although its specific application will depend on the chassis and configuration of each car. Always verify compatibility with your setup.

What track systems is the car mounted with these wheels compatible with?

The wheel itself is independent of the track system. The car's compatibility with the track (Scalextric, Ninco, Scaleauto, Carrera…) depends on the guide, chassis, and tyres used, not the wheel.

Can I use these wheels in club racing?

Yes, as long as the championship regulations allow the use of aluminium wheels in the corresponding category. Check your club's rules before homologating the setup.
