Tyre 20x11mm G25

Slot.it Tyre 20x11mm G25: controlled grip with the reference compound from the Italian brand

Slot.it is synonymous with precision in every detail, and its tyres are no exception. This slick rubber tyre in G25 compound with dimensions 20x11mm (Drw. 1171, factory reference PT1172G25) is designed to provide predictable and balanced behaviour on Sport track, responding with the consistency demanded by both club racing and meticulous preparation.

Tyre Features

• Dimensions: 20mm diameter × 11mm width.
• Profile: Slick, optimised to maximise the contact surface with the track.
• Compound: G25, medium-soft rubber within the Slot.it catalogue, designed to offer good grip without sacrificing durability.
• Reference Drawing: 1171 (Drw. 1171), internal identifier from Slot.it for the geometry of this tyre.

Function and Performance

The G25 compound occupies a middle position in the hardness scale of Slot.it: soft enough to generate grip in fast corners and tight radii, but with the necessary consistency to withstand long sessions without deforming or losing roundness. On track, this translates into a clean response to acceleration and a slip resistance that helps keep the car glued to the track even in higher speed configurations.

The slick profile ensures uniform contact with the surface, especially relevant on plastic or braid tracks where the transfer of torque to the ground makes the difference between a manageable car and one that slips during acceleration.

Compatibility and Mounting

This tyre is designed for the axles and rims of the Slot.it range whose dimensions correspond to the 20x11mm mounting. Before mounting, it is advisable to verify that the inner diameter of the tyre fits correctly to the rim used, and that the total width does not compromise the wheel arch of the chassis in question. A fine sanding after mounting allows for precise diameter matching and further improves contact with the track.

Mounting and Preparation

To get the most out of the G25 compound, we recommend:

1. Carefully mount the tyre onto the rim, ensuring it is centred correctly.
2. Turn or sand the tyre on the axle itself to ensure a uniform diameter around the circumference.
3. Clean the surface with a slightly damp cloth before each session to remove accumulated dust and restore grip.
4. Avoid using aggressive traction liquids that may prematurely degrade the compound.

Frequently Asked Questions

What does the G25 compound mean in the Slot.it catalogue?

G25 identifies the hardness and formulation of the rubber within the Slot.it reference system. It is a medium-soft compound, balanced between grip and lifespan, suitable for regular club use and competition where consistency is sought over extreme grip.

Is it compatible with any Slot.it rim?

Not necessarily with all. You must check that the dimensions of the rim —especially the width and outer diameter— are compatible with a 20x11mm tyre. Consult the Slot.it catalogue or the specifications of the wheel-rim set you are using.

What is the difference between the slick profile and other profiles?

The slick profile, being completely smooth, maximises the contact patch with the track. This favours grip on clean and homogeneous surfaces, which is the usual scenario on both home and club slot tracks.

When should tyres be changed?

When irregular wear, loss of roundness, cracks in the compound, or a noticeable reduction in grip that cannot be restored with cleaning is observed. In competition, many drivers check them after each session and renew them frequently to maintain consistent performance.

Can I use these tyres on UNIVERSAL track?

The tyre itself is not limited by the type of track, but it is a component designed within the Slot.it ecosystem, whose reference for chassis and rims is optimised for Sport track. Its use on universal track will depend on the chassis and rim on which it is mounted.

The Slot.it 20x11mm G25 tyre (ref. PT1172G25 / SIPT1172G25) is a slick rubber tyre with a medium-soft compound, designed for slot car racing.
