Slot.it Slick Tyre 20x10mm in G25 Compound: The Detail That Makes a Difference on Track

Within the Slot.it spare parts catalogue, tyres are possibly the component that most influences the actual behaviour of a car. This slick tyre of 20x10mm with G25 compound (technical drawing 1171) is made of rubber and adheres to the philosophy of the Italian brand: to offer replacement parts with the same consistency and tolerances as those fitted on their production cars.

Main Features

• Size: 20x10mm — slick profile with no tread pattern.
• Compound: G25, medium-soft rubber aimed at traction and constant grip.
• Reference Technical Drawing: Drw. 1171 (PT1171G25).
• Material: synthetic rubber, Slot.it manufacturing.

Function and Performance

The G25 compound from Slot.it is one of the most used in club setups because it offers a solid balance between grip and durability. Being a slick profile, it maximises the contact surface with the track, resulting in a more direct response in corners and less tendency to abrupt sliding. The consistency of the material allows the car's behaviour to be predictable and reproducible throughout a complete session.

Compatibility and Installation

This tyre is designed for the axles and rims in the Slot.it catalogue that accommodate the 20x10mm size. Before installation, it is advisable to check that the rim has the appropriate support diameter so that the tyre fits without slack or excessive tension. A correct installation, with the tyre perfectly centred and without deformations, is as important as the choice of compound. If necessary, a light sanding around the rim while mounted ensures perfect concentricity.

Installation and Preparation

• Carefully mount the tyre onto the corresponding rim without deforming the profile.
• Turn if necessary to achieve concentricity and the desired working diameter.
• Clean the surface of the tyre before each session to remove dust or debris that may reduce grip.
• Avoid contact with solvents or oils that may alter the properties of the compound.

Ideal for…

Any preparer or driver using Slot.it cars who wants to keep their tyres in optimal factory conditions. It also serves as a reference option for those looking to explore different compounds and compare the behaviour of G25 against other hardnesses available in the brand's catalogue.

Common Mistakes

• Mounting the tyre on a rim with the incorrect diameter, resulting in an uneven contact footprint.
• Not turning after mounting, leaving eccentricity that causes vibrations and loss of grip.
• Using inappropriate lubricants or cleaners that degrade the compound.

Frequently Asked Questions

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

G25 is the designation that Slot.it uses to identify a specific rubber formulation. It indicates the hardness and composition of the material, factors that determine the level of grip, cornering response, and tyre lifespan.

How many units does this item include?

The information available in the reference does not specify the exact number of units per bag. We recommend checking directly on the product page or contacting us before ordering if you need a specific quantity.

Is it necessary to turn these tyres before using them?

It is not strictly mandatory, but it is highly recommended in a competitive context. Turning ensures that the tyre is perfectly concentric with the axle, eliminating any vibrations and ensuring a uniform contact footprint around the circumference.

What type of track are these tyres compatible with?

As a Slot.it replacement, it is aimed at Sport track systems (Sport lane), although the final behaviour depends on the complete setup of the car and the surface conditions.

Can the G25 compound be used in club competitions?
