URANO EVO II TYRE 16.2×10 mm

Urano EVO II: the 10 mm wheel from Sloting Plus for those who do not accept compromises on track

The Urano EVO II SP022516 wheels from Sloting Plus are the brand's response to a very specific need in competitive slot racing: to have a wide, precise, and lightweight wheel that can withstand the pace of the most demanding sessions without introducing any uncontrolled variables to the car's behaviour. With 16.2 mm in diameter and 10 mm in width, they are positioned at the high end of the Urano EVO II range and are designed for the rear axle of setups that require more contact surface.

Function and performance

The width of 10 mm plays a decisive role in tuning: it allows for the fitting of wide-profile tyres without them deforming or coming off under lateral force in corners. The result is a more uniform footprint, a more stable load distribution, and more predictable traction on corner exits. For those who methodically work on setup, this type of wheel eliminates a source of variability that often goes unnoticed.

The CNC machining ensures very tight concentricity. A wheel that does not rotate perfectly centred transmits micro-impacts to the motor and transmission, accelerating wear and generating a slight but constant loss of performance. With the Urano EVO II, that problem is eliminated from the outset.

Compatibility and mounting

These wheels are designed for standard 2.38 mm (3/32") axles, the most common diameter in 1/32 scale racing. The attachment is made using a M2.5 grub screw, which can be operated with a 1.35 mm Allen key. This system guarantees a solid grip on the axle and prevents any play even after long sessions of intense use or frequent tyre changes.

The lightweight technical aluminium used in their construction helps to reduce unsprung weight and the gyroscopic effect of the rolling assembly, two factors that directly influence the car's agility when changing direction.

Mounting and preparation

Before mounting the tyres, it is advisable to ensure that the axle is clean and free of burrs so that the grub screw seats correctly. If foam tyres are used, it is recommended to let the assembled unit rest for a few minutes before grinding, as aluminium does not absorb adhesives and the tyre-wheel bond depends solely on pressure fit or perimeter gluing. The 10 mm width provides a generous support surface for grinding, making it easier to achieve a perfectly homogeneous final diameter.

Common mistakes

• Over-tightening the grub screw: this can mark the axle and hinder subsequent adjustments. A firm but moderate tightening is sufficient.
• Fitting tyres narrower than the wheel: this reduces the useful contact surface and negates part of the advantage provided by the 10 mm width. Always use tyres sized for this width.
• Not checking concentricity after mounting: although CNC machining is very precise, a small chip or dirt residue between the wheel and axle can introduce eccentricity. A quick check with the motor running before going on track is a habit worth adopting.

Frequently asked questions

What axle diameter are these wheels compatible with?

The Urano EVO II SP022516 are designed for 2.38 mm (3/32") axles, the most common standard in 1/32 scale slot racing chassis.

What Allen key do I need for the grub screw?

The grub screw is metric M2.5 and requires a 1.35 mm Allen key. It is important not to use a worn key to avoid rounding the internal hexagon.

How many wheels are included in the set?

The reference SP022516 includes 2 wheels.

What type of tyre are they designed for?

The 10 mm width is optimised for wide tyres, both foam and rubber, that require a solid support base and a wide contact surface. Check the compatibility of sizes with the tyre manufacturer before combining them.

Can I use them on the front axle?

Technically it is possible if the chassis allows it, although their width and weight make them particularly suitable for the rear axle, where traction and stability are priorities.

Can tyres mounted on these wheels be ground?

Yes. The rigidity of the technical aluminium means that these wheels can withstand the grinding process perfectly, providing a stable and deformation-free reference to achieve a homogeneous final diameter.

The Sloting Plus Urano EVO II SP022516 wheels (16.2×10 mm) are a top-tier slot car component for 1/32 scale racing. CNC-machined from lightweight technical aluminium, they deliver perfect concentricity and outstanding stability on rear axles. Compatible with standard 2.38 mm (3/32") axles and secured by an M2.5 grub screw, these wide-profile wheels are the go-to choice for competitive slot car builders seeking consistent performance and reliable tyre mounting.
