CLASSIC REAR 21 x 10 SUPERGRIP EVO

The NSR Supergrip Evo rear tyre for classic bodies: grip, consistency, and precision in every corner

The reference NSR5236EVO corresponds to the rear tyre from the Classic Rear series by NSR, in size 21 x 10 and featuring the Supergrip Evo compound. This is a direct evolution of the renowned NSR Supergrip range, reformulated to provide greater grip consistency throughout the session without sacrificing immediate response during acceleration.

Main features

• Dimensions: 21 mm diameter x 10 mm width — dimensions designed for rear axles of classic body slot cars (coupes and lower-profile sedans).
• Supergrip Evo compound: new generation soft rubber blend that balances maximum grip with improved durability compared to the previous version.
• Optimised profile: wide contact patch that enhances traction on corner exit and stability on fast straights.
• NSR manufacturing: very tight production tolerances that ensure balanced mounting, with no need for prior truing in most cases.

Compatibility and mounting

The Classic Rear 21x10 tyre is designed to fit rear wheels compatible with the NSR 21x10 format. It is commonly found in combination with the brand's own plastic or aluminium wheels for classic bodies. Before mounting, it is advisable to clean the wheel with isopropyl alcohol to ensure proper adhesion of the tyre and prevent it from working loose during the race.

On-track performance

The Supergrip Evo compound provides progressive bite: it is not as aggressive when cold as pure racing compounds, which facilitates warming up and reduces the risk of oversteer in the early laps. Once at temperature, it offers a very high level of traction that remains stable over several runs, something that club racers with wooden or plastic tracks will particularly appreciate.

Ideal for…

• Club racers competing with classic body slot cars who seek a reliable and consistent tyre.
• Enthusiasts wanting to get the most out of their NSR Classic models without resorting to extremely soft compounds with short lifespans.
• Tuners prioritising the balance between grip and tyre longevity during a long day of racing.

Considerations

As with any soft compound tyre, it is advisable to store them in a cool place, away from direct light and heat sources, to preserve the rubber's properties. If the tyres have not been used for a while, a light cleaning with adhesive tape or a slightly damp microfibre cloth can restore their original feel.

Frequently asked questions

Do I need to true the NSR5236EVO tyre before racing?

In most cases, NSR's manufacturing tolerances allow them to be used directly without truing. However, if you are looking for maximum performance in competition, a slight truing around the circumference helps achieve an absolutely uniform diameter and improves axle balance.

What wheels is this tyre compatible with?

It is designed for 10 mm wide wheels with an inner diameter compatible with the NSR 21x10 format. Check the NSR catalogue for classic car wheels to ensure exact compatibility.

How long do Supergrip Evo tyres last compared to standard Supergrip?

The Evo version incorporates improvements in the compound formulation that, according to NSR, extend the lifespan while maintaining a similar level of grip. In practice, club users report that they last several race days with good performance before needing replacement.

Are they suitable for plastic and wooden tracks?

Yes. The Supergrip Evo compound performs well on both types of surface, although — as with any soft rubber — it performs particularly well on wooden tracks where rail cleanliness enhances adhesion.

How many units are included in the NSR5236EVO reference?

Check the product packaging, as NSR sells its tyres in different formats. The exact information regarding the number of units per package is indicated on the box.
