SUPERGRIP rear tyres 19x9.5 16.5/17

NSR SUPERGRIP Rear Tyres 19×9.5 mm — precise traction for Ø16.5/17 rims

The NSR SUPERGRIP tyres are one of the most commonly used references in the preparation of competitive slot cars within the NSR catalogue. Their SUPERGRIP compound is formulated to provide consistent grip on various track types, being especially appreciated by tuners who seek a solid balance between grip and durability.

Technical Specifications

• Tyre dimensions: Ø 18.5 mm × L 9.5 mm
• Rim compatibility: Ø 16.5/17 mm rims (NSR codes 5030 and 5031)
• Diameter once mounted on Ø16.5/17 rim: Ø 19.5 mm
• Position: Rear axle
• Compound: SUPERGRIP
• Not compatible with Air System rims

Function and Performance

The SUPERGRIP compound from NSR is designed to effectively transmit the motor's power to the track, minimizing slip during starts and high-speed corners. As a rear tyre, its primary function is traction, so choosing the correct compound has a direct impact on the car's behaviour on track.

The size 19×9.5 mm is very versatile within the NSR ecosystem, being compatible with several chassis platforms from the Italian manufacturer when using the reference rims 5030 or 5031.

Compatibility and Installation

Before mounting these tyres, ensure that your rims correspond to the codes NSR 5030 or NSR 5031 (rim diameter Ø16.5/17 mm). Once installed, the rim+tyre assembly reaches an outer diameter of Ø19.5 mm, a key figure for calculating the gear ratio and the car's top speed behaviour.

Important: These tyres are not compatible with NSR Air System rims. If you are using Air System rims, please consult the specific references for that system.

Installation and Preparation

For optimal installation, we recommend using a specific slot tyre glue in the right amount, avoiding excess adhesive that could deform the tyre profile. Once glued, it is advisable to true them on a trueing tool or tyre sander to ensure perfect concentricity of the assembly and that the car runs without vibrations. A well-trued tyre makes a real difference in lap consistency.

Common Mistakes

• Using these tyres on Air System rims: they are not compatible. Always check the appropriate reference for your rim type.
• Not truing the tyres after installation: even if the fit is good, truing ensures uniform contact with the track.
• Confusing the unmounted tyre diameter (Ø18.5 mm) with the final diameter mounted on the rim (Ø19.5 mm). For transmission calculations, always use the mounted diameter.

Frequently Asked Questions

What is the actual diameter of the tyre once mounted on the rim?

Once mounted on a Ø16.5/17 mm rim (NSR codes 5030 or 5031), the assembly reaches an outer diameter of Ø19.5 mm. This is the value you should use to calculate the gear ratio.

Are they compatible with NSR Air System rims?

No. These SUPERGRIP tyres are not compatible with Air System rims. For that type of rim, NSR has specific references available.

Which NSR rims are they compatible with?

They are compatible with NSR rims of Ø16.5/17 mm, specifically references 5030 and 5031.

Do I need to true the tyres after mounting them?

It is not mandatory, but it is highly recommended in a competitive context. Truing ensures that the tyre contacts the track uniformly across its entire surface, eliminating vibrations and improving lap consistency.

In which position are they mounted, front or rear?

These tyres are designed for the rear axle, where they serve the function of traction. They are not intended for use on the front axle.
