Aluminium wheel 17.2x10mm. Lightweight Axles 3/32

The Lightweight rim from Scaleauto: less weight, more precision in every corner

Within the aluminium spare parts catalogue of Scaleauto for 1/32 scale, the rim SC-4033F25 represents the brand's commitment to reducing unsprung mass. With dimensions of 17.2x10mm and designed for 3/32" axles, it fits into the most common slot car setups in this scale.

Function and performance

The Lightweight concept is not a marketing term: it involves a machined aluminium rim design that minimises material without compromising stiffness or concentricity. In practice, this translates to:

• Lower rotational inertia, improving response in acceleration and braking.
• Reduction of the total weight of the rolling stock, especially relevant on the front axle where balance is more sensitive.
• Greater mounting precision thanks to the aluminium machining, ensuring very tight concentricity and vibration-free running.

Compatibility and mounting

This rim is designed for 3/32" (2.38mm) axles, the most widespread standard in 1/32 slot cars. Its dimensions of 17.2mm diameter and 10mm width place it in an intermediate profile, suitable for wide profile tyres in competition setups or intensive club use.

As it is an aluminium piece, it is recommended to use a suitable press tool to mount it onto the axle without damaging the machining. It is also advisable to check alignment and concentricity once mounted, especially if used on the rear axle.

Mounting and preparation

• Ensure the axle is clean and free of burrs before installation.
• Use an appropriate pressing tool; avoid direct impacts that may deform the housing.
• Check concentricity with a dial gauge or by manually rotating the axle before mounting the tyre.
• Adjust the lateral position according to the chassis track width.

Common mistakes

• Mounting the rim on an axle with rust or glue residue, which prevents a proper fit.
• Forcing the mounting with inappropriate tools that deform the central bore.
• Not checking concentricity after mounting, which can lead to vibrations and uneven tyre wear.

Ideal for…

This rim fits perfectly in the preparation of 1/32 slot cars aimed at club competition or performance improvement on track. The Lightweight profile from Scaleauto is designed for those who fine-tune every gram of their setup and seek a more direct response without sacrificing reliability.

Frequently asked questions

What axle diameter is this rim for?

It is designed for 3/32" (approximately 2.38mm) axles, the most common size in 1/32 slot cars.

What advantage does a Lightweight rim have over a standard rim?

The Lightweight version reduces the weight of the rolling assembly, which decreases rotational inertia and improves response in acceleration and direction changes.

Can it be used on the front and rear axle?

Yes, although its most common application is on the rear axle due to its direct impact on traction. It also contributes to weight reduction and improves the car's balance on the front.

What tyres are compatible with this rim?

Compatible tyres are those designed for rims with a diameter of 17.2mm and a width of 10mm. Scaleauto offers a wide range of 1/32 tyres that fit these dimensions; consult the catalogue to find the profile that best suits your track and driving style.

Is any adhesive needed to secure the tyre to the rim?

In competition, a small amount of contact glue is usually applied to the inside of the tyre to prevent it from spinning on the rim under load. In recreational use, it may not be necessary.
