3DR wheel 16.2x8mm for axle 2.38"

Precision to the millimetre with the 3DR 16.2x8mm wheel for 2.38" axle

When wheel mounting matters — and in slot it always matters — every tenth of a gram and every hundredth of a millimetre counts. This 3DR wheel of 16.2x8mm for 2.38" axle is made from high-quality 3D resin, balancing strength and flexibility to withstand the demands of tuning and competition.

Features and function

• Dimensions: 16.2 mm diameter × 8 mm width.
• Compatible axle: 2.38" (common standard in many slot chassis).
• Material: High-quality 3D resin, with good mechanical resistance and some flexibility to absorb impacts without deforming.
• Weight: 0.38 g per unit — reduced mass that favours acceleration and reduces rotational inertia.

Mounting and preparation

The process of mounting resin wheels follows the same guidelines as any precision wheel: fit to the axle with the correct clearance, check for centring, and if mounting silicone or foam tyres, pre-sanding the wheel to improve glue adhesion. The low weight of this part helps keep the wheel and tyre assembly as light as possible, something especially valued in club racing-oriented builds.

Who is this wheel for?

It is particularly useful for tuners and enthusiasts working with chassis compatible with 2.38" axles, whether in production cars or in custom builds. The combination of dimensions 16.2x8mm places it in a versatile intermediate range, suitable for both competition configurations and recreational builds seeking well-sized and lightweight wheels.

Common mistakes to avoid

• Mounting the wheel on an axle of a different diameter than indicated: the fit must be correct from the start to avoid eccentricities.
• Not checking the centring before gluing the tyre: a poorly centred wheel introduces vibrations that affect track behaviour.
• Applying too much adhesive when mounting the tyre: excess can unbalance the assembly due to irregular mass distribution.

Frequently asked questions

What axle diameter does this wheel accommodate?

It is specifically designed for a 2.38" axle, which is the most widely used standard diameter in slot chassis from various brands.

How does a 3D resin wheel differ from a conventional plastic wheel?

3D resin allows for greater dimensional precision in the manufacturing process and offers a combination of rigidity and flexibility that injected plastic wheels do not always achieve. Additionally, it facilitates finishes that are truer to nominal measurements.

Is it compatible with silicone and foam tyres?

Yes. The wheel accepts both types of tyre. For better adhesion, it is recommended to lightly sand the outer surface before applying the adhesive.

How many units does the product include?

The available information indicates that the reference weight is 0.38 g per wheel. Check the purchase sheet for the exact number of units included in the packaging.

What tools are recommended for mounting?

A wheel plate or hand lathe to check centring, fine sandpaper to prepare the surface, and specific adhesive for slot tyres are the basic elements for correct mounting.

The 3DR 16.2x8mm wheel for 2.38" axle is a high-quality resin slot car wheel designed for precise fitment and reduced rotational inertia. Weighing just 0.38 g, it is ideal for club racing builds and custom chassis projects requiring accurate, lightweight wheel assemblies. Compatible with standard 2.38" axle diameter, this slot car wheel suits both silicone and foam tyre setups.
