Slot.it Tyres 20x10mm with F30 Compound: Performance Measured to the Millimetre

When grip makes the difference between winning and losing by a tenth, the choice of tyre is no longer a secondary detail. Slot.it has been offering a range of technical rubbers designed for those who fine-tune every aspect of the car for years, and these 20x10mm tyres with F30 compound are a clear example of that philosophy: precise geometry, consistent compound, and a pack of 4 units ready to mount on both axles.

Main Features

• Size: 20x10mm — outer diameter x width.
• Compound: F30, medium-soft hardness formulation aimed at track grip.
• Pack Contents: 4 tyres.
• Brand: Slot.it — reference SIPT28.

Function and Performance

The F30 compound from Slot.it is positioned at a hardness that seeks the balance between immediate bite and controlled wear. It is not the softest rubber in the catalogue, making it interesting for long club sessions where an excessively soft compound would degrade before the end of the heat. The 20x10mm profile fits a variety of common rear wheels in Slot.it 1/32 scale cars.

Compatibility and Mounting

These tyres are designed to fit the rear wheels of Slot.it cars compatible with this size. As with any new rubber, it is advisable to check the fit on the wheel before gluing: a well-tensioned and perfectly centred tyre is the foundation of good rolling. If gluing, use specific slot rubber adhesive in minimal quantity to avoid imbalances.

To achieve the best performance, it is recommended to lightly turn the rubber once mounted on the axle, ensuring concentricity and eliminating any residual vibration. A couple of gentle passes with fine-grit sandpaper is sufficient to leave it perfectly round.

Ideal for…

• Club competitors looking to replace rear tyres with guaranteed Slot.it origin.
• Preparers wanting to standardise the compound across all cars in a team.
• Enthusiasts testing different grip configurations based on track type.

Points to Consider

Always check the size of your car's wheels before ordering: Slot.it offers several tyre sizes in its catalogue, and 20x10mm is a specific size. Consult the manual or technical sheet of the chassis to confirm exact compatibility.

Frequently Asked Questions

What does the F30 compound mean in Slot.it tyres?

F30 is Slot.it's designation for a medium-soft hardness rubber formulation. The number refers to the hardness of the compound: the lower the number, the softer and more immediate grip; the higher the number, the harder and more durable. F30 offers an adequate balance for club track use.

How many tyres are included in the pack?

The SIPT28 pack includes 4 tyres, sufficient to equip both axles of a car or to have two spares after mounting the rear axle.

Do I need to turn them before using them?

It is not strictly mandatory, but it is highly recommended for competition. Turning the tyres once mounted on the axle ensures perfect concentricity and eliminates vibrations that can affect the car's behaviour in corners.

Are they compatible with Scalextric or Ninco tracks?

The tyre itself does not depend on the track system, but on the car's wheel. What determines compatibility is that the 20x10mm size fits your model's wheels. Slot.it manufactures cars aimed at the Sport track, but the tyre can be mounted on any car that uses that wheel size.

What glue is used for proper fixing?

Low-viscosity cyanoacrylate adhesive specific for slot rubbers is recommended, applied in very small quantity to avoid the rubber becoming off-centre or having hard spots.
