Extreme Grip F 1 Tyres (x 4)

NSR Extreme Grip F1 Tyres: Competitive Grip in Every Corner

The reference NSR5307 includes four tyres from NSR's Extreme Grip line, specifically designed for 1/32 scale Formula 1 bodies. One thing NSR has demonstrated over the years is that the tyre is one of the most determining factors in the performance of a slot car on track, and this range is a true reflection of that philosophy.

Function and Performance

The NSR Extreme Grip tyres are formulated with a soft rubber compound that seeks to balance immediate grip and reasonable durability. On a clean track with good grip, they effectively transmit the motor's power to the ground, reducing wheel spin on starts and providing stability in tight corners.

The F1 profile is designed for the geometries of 1/32 scale single-seater cars, adapting to the rear tyre holders of models that use this type of rim.

Compatibility

These tyres are intended for NSR slot cars with Formula 1 bodies that use the rim corresponding to this reference. Before mounting, it is advisable to always check the diameter and width of the tyre against the rim of your specific model, as NSR offers various sizes within its catalogue.

Mounting and Preparation

The mounting process follows the usual steps in competitive slot racing:

1. Mount the tyre on the rim ensuring it is centred and free of air bubbles.
2. Apply a minimal drop of cyanoacrylate glue on the inside if intensive use is anticipated.
3. Turn on the car itself to ensure perfect roundness and eliminate any vibration.
4. Clean the surface with a slightly damp cloth before the first run to activate the compound.

Turning is especially important for soft rubber tyres: a small eccentricity can result in oscillations that reduce top speed and cornering stability.

Common Mistakes

• Not turning: new tyres rarely come perfectly round from the factory. Skipping this step reduces performance.
• Excess glue: soaking the rubber with cyanoacrylate hardens the compound and diminishes grip.
• Dirty track: a soft rubber tyre accumulates dirt quickly. Regularly cleaning the track extends the lifespan and maintains grip.

Ideal for…

Club competitors looking for a direct replacement tyre for their NSR single-seaters, as well as enthusiasts wanting to restore the original performance of a car that has already seen use. The pack of 4 units allows for a complete rear axle renewal and keeps a spare pair on hand.

Frequently Asked Questions

How many tyres are included in this pack?

The NSR5307 pack includes 4 tyres.

Are they front or rear tyres?

The NSR F1 designation corresponds to the application in 1/32 scale Formula 1 cars. The front or rear position depends on the specific model; consult the NSR catalogue to verify the correct reference for each axle.

Do I need to turn them before use?

Yes. Turning is highly recommended for competition tyres: it ensures roundness and eliminates vibrations that affect track performance.

Are they compatible with cars from other brands?

They may be compatible if the diameter, width, and type of rim match those of your model, but NSR designs them for its own range. Always check the measurements before mounting.

How long do these soft tyres last?

It depends on the compound, track surface, and car power. Generally, soft rubber tyres offer greater grip at the cost of a shorter lifespan compared to hard rubber tyres. For intensive recreational use or club championships, it is advisable to have spare units on hand.
