Universal wheel 14.6x8mm

Duralumin, precise geometry and controlled weight to get the best out of your slot car

The universal rim SP021108 from Sloting Plus is a preparation spare part designed for those seeking maximum control over the weight and rolling dimensions of their car. With measurements of 14.6 mm in diameter and 8 mm in width, it fits a wide variety of mounts and has become a common reference in club preparation workshops.

Main features

• Material: duralumin, with an excellent balance between stiffness and reduced weight.
• Dimensions: 14.6 mm in diameter × 8 mm in width.
• Weight: 0.75 g per unit, allowing for low rotating masses and enhancing acceleration response.
• Fixing: M2.5 × 3 mm allen grub screw.
• Bag contents: 2 rims + 2 allen grub screws.

Function and performance

In slot preparation, the unaccounted weight in rotating masses — rims, tyres, axles — has a direct impact on the inertia of the rolling chassis. Working with lightweight duralumin rims like this reduces that effect, gaining response when accelerating and facilitating control during braking. Duralumin also provides a homogeneous surface that helps the tyre seat evenly, resulting in a more stable and predictable run.

Compatibility

The term universal indicates that this rim is designed to fit various chassis and configurations, both on universal track (Scalextric, Ninco) and sport track (Scaleauto, Slot.it). The fixing with M2.5 × 3 mm allen grub screw is one of the most widespread standards in the spare parts and preparation tools segment, making its integration into multiple mounts easier.

As always when mounting rims, it is advisable to check that the diameter and width are compatible with the chosen tyre and that the wheelbase of the chassis allows for mounting without interference with the body or chassis.

Mounting and preparation

The mounting is straightforward: insert the included allen grub screw into the axle and tighten with the appropriate tool for M2.5. It is recommended not to overtighten to avoid damaging the axle or the rim itself. Once mounted, it is good practice to check the concentricity with a dial gauge or simply by rolling the assembly on a flat surface before gluing the final tyre.

Common mistakes

• Confusing rim width with the necessary tyre width: the tyre should have a width equal to or slightly greater than the rim for a proper fit.
• Using grub screws with a thread different from M2.5: this can damage the axle or fail to ensure a secure fixing.
• Not checking concentricity after mounting, which can cause vibration and loss of grip.

Frequently asked questions

How many rims are included in the bag?

The bag contains 2 duralumin rims and 2 M2.5 × 3 mm allen grub screws.

What size allen key do I need to mount these rims?

The included grub screw is M2.5, so you will need an appropriate allen key for that diameter. Sloting Plus offers specific preparation tools for this type of screw.

Can I use these rims on Scalextric and Ninco tracks?

Yes. As this is a universal rim, it is compatible with configurations for universal track such as Scalextric and Ninco, provided that the rest of the rolling chassis (axle, chassis, tyre) is compatible with the specified dimensions.

What advantage does duralumin have over plastic?

Duralumin offers greater stiffness, better concentricity, and a very controlled weight. This translates into a more precise run and a more predictable response from the car, especially relevant in competition-oriented preparations.

What tyre is compatible with this rim?

With 8 mm in width and 14.6 mm in diameter, it accepts tyres with dimensions compatible with those specifications. Check the Sloting Plus catalogue or the spare parts from other leading brands such as NSR or Slot.it to find the tyre that best suits your setup.

The Sloting Plus SP021108 is a 14.6×8mm duralumin universal rim weighing just 0.75 g, supplied with M2.5×3mm allen grub screws — two rims and two screws per pack. A go-to slot car preparation part for club racers and hobbyists looking to fine-tune rotating mass on Scalextric, Ninco, Scaleauto or Slot.it compatible setups.
