CLASSIC REAR 21 x 11 ULTRAGRIP

Real grip from the first turn: NSR Classic Rear 21x11 Ultragrip

The NSR Classic Rear 21x11 Ultragrip tyres (reference NSR5242) are designed for those who do not want to rely on chemical treatments to get performance from their car. The Ultragrip compound from NSR is one of the softest compounds in their catalogue, resulting in a more effective contact patch and immediate response in corners.

Features and function

• Ultra-soft Ultragrip compound: formulated to maximise grip without the need for any pre-mounting treatment.
• Dimensions 21 x 11: specific sizes for the rear axle of NSR's Classic range cars.
• Compatibility: designed to fit NSR5002 (16) wheels or rims of similar diameter.
• Immediate use: ready for the track without additional preparation, making them especially convenient for club sessions or quick practice runs.

Track performance

The ultra-soft compound performs very well on plastic and wooden tracks, providing traction from the start. As no treatment is required, the behaviour is predictable and consistent throughout the session. For enthusiasts who prefer a clean setup without chemical variables, this is a solid choice.

Mounting and preparation

Mounting on NSR5002 (16) wheels is straightforward. Although the compound is already factory-optimised, as with any soft tyre, it is recommended to check the concentricity once mounted and, if a lathe is available, to give a light touch-up to ensure uniform rolling across the entire perimeter.

Ideal for…

• NSR Classic range cars that use NSR5002 (16) wheels.
• Club drivers looking for consistent grip without complicated preparation.
• Enthusiasts wanting to renew rear tyres while maintaining the car's original specifications.
