CLASSIC REAR 20.5x 10 SUPERGRIP

NSR Classic Rear Supergrip 20.5×10 Tyres: Reliable Traction for Classic Profile Slot Cars

The NSR Classic Rear 20.5×10 Supergrip (ref. NSR5253) are the rear tyres designed by NSR for classic profile slot car models that require a soft and grippy compound. With dimensions of 20.5 mm in diameter and 10 mm in width, they fit into the typical housings of this family of cars and provide the level of grip demanded by both club track running and the most competitive racing.

Main Features

• Supergrip Compound: high-adhesion rubber developed by NSR to maximise rear traction without compromising durability.
• Dimensions: 20.5 mm outer diameter × 10 mm width. Classic profile, suitable for wheels of the same family.
• Consistent Construction: uniform hardness and elasticity between units, ensuring symmetrical behaviour on the rear axle.
• Easy Mounting: they mount directly onto the corresponding wheels without the need for special tools or additional gluing in most applications.

Behaviour and Performance

The NSR Supergrip compound is characterised by offering progressive bite from the first lap. Unlike harder rubbers, it does not require a long warming-up period to perform; it connects well with the track practically from the start, which is highly valued in club sessions with limited time. Its 10 mm width provides a generous contact patch for a classic profile tyre, translating into stability in fast corners and good response to direction changes.

Consistency between units is one of NSR's strengths in its tyre line: when mounting a pair from the same batch, it is common for both wheels to have the same effective diameter, avoiding vibrations or imbalances that would penalise the car's behaviour.

Compatibility and Mounting

These tyres are designed to be used with NSR classic rear wheels compatible with the 20.5×10 profile. Before mounting, it is advisable to check that the wheel does not have any rubber residue from the previous set and that the outer diameter of the new tyre is suitable for your car's chassis. If greater seating adhesion is desired, a small amount of contact glue specifically for slot rubber can be applied inside the tyre, although in many mounts the fitting pressure is sufficient.

To achieve maximum performance, it is recommended to true the tyres on a lathe or with fine sandpaper after mounting, ensuring that the effective diameter is perfectly uniform around the entire circumference.

Ideal for…

• Club drivers looking for a reliable rear tyre with consistent grip for classic profile NSR cars.
• Competitors needing to replace the stock set with a higher-adhesion rubber.
• Enthusiasts wanting to improve their slot car's performance without making mechanical modifications.

Points to Consider

The Supergrip tyres are more sensitive to track dirt than standard compounds: it is advisable to clean the track before each session to maintain grip levels. Store them away from direct light and heat when not in use to preserve the compound's properties in the long term.

Frequently Asked Questions

How many tyres are included in the NSR5253 pack?

The NSR5253 reference corresponds to the standard pack from NSR for this range. We recommend checking the product sheet in the store or contacting us to confirm the exact quantity per sales unit, as NSR typically sells its tyres in packs of 4 units, although this may vary by reference.

Are they compatible with wheels from other brands?

They are designed for the corresponding NSR classic profile wheels. They may work with wheels from other brands that share the same seating dimensions, but we recommend verifying the fit before considering the tyres suitable for competition.

Do I need to glue these tyres to the wheel?

In most mounts, the pressure fit is sufficient. If any lateral movement of the rubber on the wheel is detected, a minimal amount of specific slot rubber glue can be applied inside the tyre.

Is it advisable to true these tyres after mounting?

Yes, as long as you have a slot lathe. Truing the outer diameter ensures a perfectly uniform circumference, eliminates possible vibrations, and extracts the maximum performance from the Supergrip compound.

How should I store them?

Store them in a cool, dry place away from direct sunlight or heat sources. These conditions preserve the elasticity and adhesive properties of the compound for a longer time.
