TYRE 16X8MM

The Slot.it 16x8mm C1 Tyre: A Established Reference in the Slot World

With the reference SIPT1088C1, Slot.it presents this 16x8 mm tyre in C1 compound, previously marketed under the code PT20. A change in nomenclature, the same philosophy: a tyre with predictable behaviour, designed for those seeking consistency lap after lap.

Main Features

• Dimensions: 16 mm outer diameter × 8 mm width.
• C1 Compound: medium-soft hardness formulation that balances grip and durability.
• Previously PT20: same technical reference with new coding in the Slot.it catalogue.
• Manufactured with Slot.it's usual dimensional precision, ensuring a clean fit and uniform rolling.

Function and Performance

The C1 compound from Slot.it is aimed at providing solid grip without sacrificing tyre lifespan. On Sport track systems —the system used by Scaleauto and Slot.it— this type of rubber performs well in both tight corners and high-speed sections, maintaining a uniform contact patch on the track.

Its 8 mm wide profile offers a generous contact surface for a rear axle, contributing to the lateral stability of the car and reducing oversteer in fast corners.

Compatibility and Mounting

As a tyre from the Slot.it range, it is sized to fit directly onto compatible rims of the same brand with this profile. Before mounting, it is advisable to check that the inner diameter of the rim corresponds to this tyre. A slight reduction or a treatment with acetone on the tread —a common preparation technique— can adjust grip to the type of track and rail conditions.

Preparation and Tuning

To get the most out of the C1 compound, we recommend:

1. Mount the tyre on the rim and turn it down until the desired exact circumference is achieved, ensuring full contact of the tread.
2. Clean the surface with a dry cloth before each session to remove dust and debris.
3. Avoid excessive use of aggressive grip products, as the C1 compound already provides sufficient intrinsic grip for most club circuits.

Ideal for…

This tyre fits perfectly into the profile of the club racer looking for a reliable, repeatable consumable with no surprises. It is also a common choice for those preparing Slot.it cars for competition in GT format or prototypes in 1/32 scale, where consistency over a long race is more valuable than maximum peak grip.

Considerations

As a rubber tyre, its behaviour may vary slightly depending on ambient temperature and the type of track surface. During prolonged running sessions, it is advisable to periodically check for irregular wear or dirt accumulation on the tread.

Frequently Asked Questions

Is the SIPT1088C1 the direct successor to the PT20?

Yes. It is exactly the same tyre with a new coding within the updated Slot.it catalogue. The dimensions and compound are identical.

How does the C1 compound differ from other Slot.it compounds?

Slot.it offers different hardnesses of compound. The C1 represents a medium-soft grip formulation, balanced for general use in clubs and competition. Softer compounds provide greater grip but wear out faster; harder compounds last longer but offer less traction when cold.

Is it compatible with rims from other brands?

The tyre is designed for Slot.it rims of the corresponding profile. It can be mounted on rims from other brands as long as the inner diameter and width are compatible, but prior dimensional verification is essential.

How many units are included in the pack?

Check the product details on the store sheet, as the quantity per pack may vary. The code SIPT1088C1 corresponds to the standard Slot.it format for this reference.

Do I need to turn down the tyre before using it?

It is not mandatory, but highly recommended if you are looking for maximum performance. Turning ensures that the entire tread is in contact with the track from the first lap, improving stability and grip.
