Slick 20x12 (4 pcs)

NSR Slick Tyres 20x12: four units to maintain pace on track

Tyres are, along with the guide and braid, one of the consumables that most influence the actual behaviour of a slot car. A worn, hardened, or incorrectly sized tyre can ruin the most careful setup work. That’s why NSR pays special attention to its range of wheels, and the Slick 20x12 (NSR5314) is one of its most commonly used references in club competition and advanced level setups.

Tyre Features

• Size: 20 mm diameter × 12 mm width.
• Slick profile: no tread, to maximise the contact patch with the track and optimise lateral grip.
• Pack of 4 units: sufficient to equip a complete rear axle and a complete front axle, or to renew two cars on the corresponding axle.
• Official NSR reference: NSR5314.

Function and Performance

The slick profile eliminates any type of tread or groove, putting the largest possible rubber surface in contact with the track. This translates into more consistent traction, especially beneficial in high-speed sections and wide-radius corners where the rubber needs to work consistently lap after lap.

The size 20×12 is common on the rear of 1/32 scale slot cars of certain stature — GT bodies, prototypes, or wide-body touring cars — although its specific use will always depend on the rim and chassis on which it is mounted.

Compatibility and Mounting

These tyres are designed to be used with the corresponding NSR rims. Before mounting them, it is advisable to check that the inner diameter of the tyre fits correctly with the chosen rim. Once mounted, it is recommended to true them (or use fine sandpaper on track) to ensure perfect concentricity and avoid vibrations that affect lap times.

NSR, along with Slot.it, Avant Slot, and Scaleauto, is one of the brands with the largest assortment of spare parts and consumables within competitive slot racing, making it easier to find the most suitable rim and tyre combination for each setup.

Mounting and Preparation — Common Mistakes

• Not truing after mounting: even new tyres can exhibit slight eccentricities. A few minutes of truing can make a difference on the clock.
• Using with incorrect size rims: a tyre that is too forced onto the rim loses symmetry and can detach in a corner.
• Ignoring wear: slicks show wear before it is visible to the naked eye. If the car starts to lose traction without an apparent issue in the guide or braid, checking the condition of the tyres is the first step.

Ideal for…

• Club competitors looking to keep their cars in optimal grip conditions.
• Preparers working with NSR chassis who need original manufacturer consumables.
• Enthusiasts who regularly perform setups and want to have spare tyres always on hand.

Frequently Asked Questions

How many units are included in the pack?

The NSR5314 pack includes 4 slick tyres measuring 20×12.

Is it necessary to true them before using them in competition?

Yes, it is highly recommended. Truing ensures the concentricity of the tyre on the rim and eliminates possible factory irregularities, improving stability and lap times.

What rims are these tyres compatible with?

They must be mounted on NSR rims whose outer diameter matches the inner diameter of this tyre. Consult the NSR rim catalogue to identify the appropriate reference for your setup.

Can any treatment be applied to improve grip?

Some competitors apply specific treatments to soften or clean the rubber. The effectiveness depends on the type of track and the regulations of the championship in which you participate, as certain treatments are not allowed in regulated categories.

When should tyres be changed?

When the car progressively loses traction without an evident problem in the guide, braid, or motor, or when irregular wear or flattening is observed on the tread.
