SLICK REAR Tyre 18.5x13 ZERO Graining NSR Formula 86/89 (4 units)

The reference rear tyre for the NSR Formula 86/89

Tyres are the only point of contact between the car and the track, and in competitive slot racing, this reality is felt in every corner. The reference NSR5287Z offers a Slick compound with ZERO Graining technology in a size of 18.5x13 mm, specifically designed for the single-seaters of the NSR Formula 86/89 series. This pack includes 4 units, sufficient to equip the rear axle of two cars or to keep a spare set ready for racing.

Function and performance

The main challenge of any slot tyre during long sessions is graining: the accumulation of rubber particles on the tread that causes loss of grip, vibrations, and erratic behaviour. NSR's ZERO Graining technology directly addresses this issue with a compound formulated to minimise the transfer of debris, keeping the contact surface clean and effective both in practice and in racing.

The dimensions of 18.5 mm in diameter and 13 mm in width provide a generous footprint that facilitates torque transfer to the track, with a low profile that helps stabilise the centre of gravity of the rear axle. The result is more linear acceleration and a more predictable response when exiting corners.

Compatibility

This tyre is designed for the rear axle of the NSR Formula 86/89 single-seaters. Always check that the diameter and width are compatible with your car's rims before mounting, as NSR offers different sizes for various setup configurations.

Mounting and preparation

• Clean the rims before mounting to ensure that the tyre seats correctly and free of impurities.
• It is common to perform a light truing to achieve a perfectly uniform diameter among the four units and eliminate possible vibrations.
• Apply the minimum amount of glue or, if the rim allows, mount dry and true the mounted tyre for greater precision.
• Before each racing session, clean the tread with a slightly damp cloth to remove any dust residue from the track.

Common mistakes

• Not truing the tyres: even the best compounds need truing to ensure perfect concentricity. Skipping this step can cause vibrations even if the tyre is of high quality.
• Mixing units from different batches: although in theory all units are the same, in demanding competition it is advisable to always use the same manufacturing batch to maintain hardness consistency.
• Excess glue: an excessive amount can contaminate the tread and negate part of the compound's grip.

Frequently asked questions

What cars are these tyres compatible with?

They are specifically designed for the NSR Formula 86/89 single-seaters. If you have doubts about compatibility with other bodies or chassis, check the specifications of your car's rear axle before ordering.

What does ZERO Graining mean exactly?

It is NSR's designation for a rubber compound formulated to reduce the formation of rubber debris adhering to the tread during use. The result is more consistent grip throughout the session, without the progressive degradation observed with conventional compounds during long sessions.

How many units does this pack include and how many cars does it cover?

The pack includes 4 rear tyres. It is enough to equip the rear axle of two complete cars, or to have a refresh set for a single car during a championship session.

Do I need to true these tyres before using them?

It is not mandatory, but it is highly recommended in competition. A light truing ensures perfect concentricity, eliminates possible manufacturing irregularities, and extracts the maximum performance from the compound from the first metre.

What is the difference between this 18.5x13 and other sizes in the NSR catalogue?

The diameter of 18.5 mm is slightly smaller than other available sizes, which implies a lower development per motor lap. This can benefit acceleration and lower the centre of gravity of the rear axle, although it affects top speed. The choice will depend on the type of track and the motor used.

Are they compatible with any type of track?

The tyre itself does not depend on the type of track, but grip can vary according to the surface. They work well on both plastic tracks like Scalextric or Ninco and on wooden or resin tracks typical of club circuits.
