Pro Plastic Wheel 15.8 x 8.2 mm 0.7g 4pcs

The Slot.it plastic wheel designed for the front axle of your 1/32 cars

Within the Slot.it spare parts catalogue, the Pro plastic wheels hold a unique place: they are reference pieces for those who care about every gram and every millimetre of their car. This reference SIWH1210PL is specifically designed for the front axle and offers dimensions of 15.8 x 8.2 mm with a weight of only 0.7 g per unit.

Function and performance

The front wheel plays a discreet yet critical role: it maintains the correct geometry of the front end, ensures that the tyre sits evenly, and contributes to the directional stability of the car during braking and corner entry. A lightweight wheel on the front axle reduces unsprung inertia and helps the car respond more faithfully to lane changes.

• Dimensions: 15.8 x 8.2 mm
• Weight per unit: 0.7 g
• Material: plastic
• Mounting system: press-fit
• Position: front axle
• Pack of 4 units

Compatibility and assembly

The press-fit mounting facilitates assembly without special tools: simply align the wheel correctly with the axle and apply even pressure until it is seated. Before mounting, it is advisable to check that the axle diameter corresponds with the wheel fit to avoid play or unnecessary tension. Refer to your Slot.it chassis documentation or the parts list of your specific model to confirm that this reference is suitable.

Assembly and preparation

To get the most out of these wheels in a competitive or carefully prepared environment:

1. Clean the axle before assembly to remove any grease or dirt.
2. Apply centred and progressive pressure, without striking directly on the wheel.
3. Once the tyre is mounted, check the concentricity by turning the axle by hand.
4. If using a wheel lathe, verify the centring before truing the tyre.

Common mistakes

The most common mistake is assuming that any wheel of similar dimensions is interchangeable. In 1/32 slot racing, differences of tenths of a millimetre in the inner diameter can result in a loose fit — leading to axle slippage — or an excessively tight fit, risking deformation. Always verify the specific reference before ordering.

Frequently asked questions

Is this wheel suitable for the rear axle?

According to the product information, it is designed for the front axle. For the rear axle, Slot.it offers specific references with different dimensions and characteristics. Check the spare parts catalogue to find the appropriate rear wheel for your model.

Does the pack include 4 identical wheels?

Yes, the pack contains 4 units of the same reference, all with the same dimensions (15.8 x 8.2 mm) and the same weight (0.7 g).

Do I need special tools for assembly?

The mounting is press-fit, so no special tools are required. However, if you use a mounting tool or a small wooden block to apply pressure evenly, you will reduce the risk of deforming the wheel during the process.

Is it compatible with Sport track?

The wheel itself is not linked to the type of track, but to the chassis and axle of the car. Slot.it develops its cars and spare parts for Sport track, but final compatibility depends on the specific model in which you will mount these wheels.

Can I true the tyre mounted on this wheel?

Yes, as long as the wheel-tyre assembly is well centred on the axle. It is advisable to check for concentricity before truing to ensure that the truing is uniform.
