URANO EVO II wheel 16.5 x 10 mm

The Sloting Plus Urano EVO II series represents the level of precision that 1/32 competition demands in every rotational detail.

The SP022520 wheels come in a 10 mm width and 16.5 mm diameter, a combination designed for the rear axle of chassis that require a wide contact base with the tyre and maximum stability in corners. Within Sloting Plus's spare parts catalogue, the Urano EVO II line occupies the top tier in terms of dimensional accuracy.

Function and performance

The CNC machining used to manufacture these wheels ensures concentricity that, in practice, eliminates vibrations at high revolutions. When the imbalance in the rotating masses is minimal, the motor's power reaches the rail cleanly without losses due to resonance or irregularities in the tyre's contact patch.

The 10 mm width is particularly relevant for wide competition tyres: it provides sufficient lateral support so that the profile does not deform or flex under load. The result is a flat and consistent contact patch, both in straight lines and during the most abrupt direction changes.

The lightweight technical aluminium reduces the rotational mass compared to steel or technical plastic options, resulting in more responsive acceleration and braking. In categories where every hundredth counts, this factor makes a noticeable difference in lap times.

Compatibility and mounting

The fixing system is based on a M2.5 grub screw, which requires a 1.35 mm Allen key. This system secures the wheel to the axle without lateral play even under the centrifugal forces generated in fast corners.

They are compatible with standard 2.38 mm (3/32") axles, the most common size in the 1/32 slot car world. Before final assembly, it is advisable to check the squareness of the axle and perform a light lapping of the mounted wheel to ensure maximum concentricity in the axle-wheel-tyre assembly.

Common errors in mounting aluminium wheels

• Over-tightening the grub screw: this can cause slight deformation in the axle housing and lead to eccentricity. Tighten firmly but without forcing.
• Not lapping after assembly: even CNC-machined wheels can exhibit tenths of a millimetre of eccentricity when combined with the axle. A fine lapping eliminates this margin.
• Mounting tyres without checking the wheel width: the 10 mm width is designed for wide profile tyres; using narrow tyres on this wheel can result in irregular contact with the rail.

Frequently asked questions

What axle diameter are these wheels compatible with?

They are designed for 2.38 mm (3/32") axles, the most common standard in 1/32 slot car chassis.

What Allen key do I need for the grub screw?

The grub screw is M2.5 and requires a 1.35 mm Allen key. It is a specific size; if you do not have it, Sloting Plus sells suitable adjustment tools for this type of fixing.

Is it necessary to lap the wheels after mounting them?

Although CNC machining minimises eccentricities, it is always advisable to perform a light lapping once mounted on the axle and with the tyre installed. This eliminates any small accumulated deviation in the assembly and achieves the most perfect contact patch possible.

How many units are included in the pack?

The pack contains 2 wheels, sufficient to equip the rear axle of one model.

What type of tyres is the 10 mm width intended for?

The 10 mm width is aimed at wide competition tyres. It provides a support base that prevents lateral deformation of the profile and ensures a flat and stable contact patch.

Can they be used on the front axle?

Technically it is possible, but their diameter and width make them especially suitable for the rear axle, where the wide contact surface and reduction of rotational mass have a greater impact on the model's behaviour.

The Sloting Plus Urano EVO II SP022520 aluminium wheels (16.5 x 10 mm) are a top-tier choice for 1/32 slot car racing. CNC-machined for absolute concentricity, lightweight technical aluminium construction and M2.5 grub screw fixing make these wheels a benchmark for competitive slot car builders using standard 3/32" axles.
