Rubber Tyre 20x12mm F1

The Slot.it slick tyre for Formula 1 scale cars

The SIPT16 is the rubber tyre in size 20x12mm that Slot.it has specifically developed under the F-1 Slick S1 profile. Within the consumables catalogue of the Italian brand, the PT series tyres are a reference for those looking to accurately replace the original component, maintaining the balance of grip and behaviour that the manufacturer has calculated for its chassis.

Features and function

• Size: 20x12mm — outer diameter x width.
• Profile: Slick S1, smooth, without tread, to maximise the contact surface with the track.
• Material: Slot.it rubber, standard formulation of the brand for the F-1 series.
• Reference: SIPT16.

The slick profile without tread is the usual choice in scale single-seaters: without water drainage channels, the entire tread works in contact with the track, resulting in greater lateral grip in corners and increased traction out of them under typical indoor usage conditions.

Compatibility and mounting

This tyre is designed as a direct replacement for Slot.it Formula 1 models that use the size 20x12mm. Before ordering, check in your car's technical documentation (or in the spare parts list for the specific model) that the reference SIPT16 is the correct one. Slot.it maintains a wide and well-documented spare parts catalogue, making it easy to identify the correct part without margin for error.

Mounting is direct onto the axle and corresponding rim. If the tyres have been mounted for a while and have lost grip, a gentle sanding with fine-grit sandpaper on a flat surface restores the rubber to its optimal state before running again.

On-track performance

Slot.it rubber offers a progressive response: it is not the softest compound on the market, but it is one of the most balanced in terms of durability and grip. For use in clubs or on Sport track systems (compatible with Scaleauto circuits, among others), its wear is controlled and predictable. If you are looking for maximum grip for timed competition, many preparers combine these tyres with a traction treatment, although for recreational use they perform perfectly as they come out of the bag.

Ideal for…

• Replacing the original tyres of Slot.it Formula 1 cars with size 20x12mm.
• Enthusiasts who want to maintain the manufacturer's original specification.
• Preparers looking for a stable rubber base to work on setup.
• Use in clubs or on private tracks, both in recreational and competitive formats.

Points to consider

Always verify the exact size that your car uses before placing an order. Slot.it has several tyre references for its different models, and although the difference of millimetres may seem small, an incorrectly sized tyre directly affects the behaviour and proper functioning of the chassis.

Frequently Asked Questions

How many units does the SIPT16 include?

The information available in the Slot.it catalogue does not explicitly specify whether the reference is sold in pairs or as individual units. We recommend checking the details of the listing or contacting us before placing the order if you need confirmation.

Is it compatible with cars from other brands?

The size 20x12mm is a common standard in scale single-seaters, so it could fit on axles and rims from other brands with the same size. However, the reference SIPT16 is designed and specified by Slot.it for its own models, and we cannot guarantee fit or optimal performance outside of that context without prior verification.

Do I need to treat them with any product before using them?

No, it is not necessary. They can be used directly as supplied. If you are looking to increase grip for competition, some drivers apply specific treatments, but for recreational or club use, no prior preparation is needed.

Can they be sanded to improve grip?

Yes. A gentle sanding with fine sandpaper on a flat surface removes the oxidised or hardened surface layer and returns the tyre to a more receptive texture. It is a common practice in slot car preparation.

What type of track are these tyres compatible with?

The tyre itself has no track restriction; the rail system is determined by the guide and chassis of the car. Slot.it cars are compatible with Sport track (Scaleauto, Slot.it), so it is on those types of circuits where you will find the performance for which they are prepared.
