Function and Performance

The Ultra Grip Classic compound from NSR is aimed at providing consistent grip response and controlled wear. The rubber profile allows for an appropriate contact patch with the track, resulting in stable traction during both corner exit accelerations and braking. It is a widely used option among enthusiasts seeking a balance between durability and performance, without the need to resort to ultra-soft pure racing compounds.

Compatibility and Installation

These tyres are designed to fit directly onto NSR rims with a 16 mm diameter. Before installation, it is advisable to clean the rim with a mild degreaser to ensure proper adhesion and centring of the tyre. Once mounted, fine turning with a slot lathe allows for equalising the diameter of both wheels and maximising contact with the track.

Preparation and Usage Tips

• Always check the diameter of your rim before mounting: the correct size is 16 mm.
• If you are going to turn the tyres, do so with light passes to avoid removing more rubber than necessary.
• Clean the tread surface before each session to remove dust and dirt that may reduce grip.
• Store unmounted tyres in a cool place away from direct light to preserve the compound.

Ideal for…

This pack is perfectly suited for club setups and regular recreational use. If you are looking for a reliable tyre for consistent running without having to change rubber in every session, the NSR Classic range is a very sensible choice. It is also useful to have several spare units on hand to avoid interruptions in running due to unexpected wear.

Frequently Asked Questions

Are these tyres compatible with rims from other brands?

As long as the rim has a diameter of 16 mm, compatibility is usually good. However, NSR designs its tyres with its own rims in mind, so the most precise fit is achieved by combining tyre and rim from the same brand.

How many units are included in the pack?

The pack contains 3 Ultra Grip Classic tyres in size 21x10 for a 16 mm rim.

Do I need to turn these tyres before using them?

It is not strictly necessary, but turning the tyres ensures a uniform diameter on both wheels and a more homogeneous contact with the track, improving the car's stability. For informal recreational use, this step can be skipped.

What is the difference between the Ultra Grip Classic range and other NSR ranges?

NSR offers different compounds depending on the desired level of grip and hardness. The Classic range provides balanced performance and greater durability than softer competition compounds, making it ideal for long sessions and club use.

What should I use to clean the rim before mounting the tyre?

A mild degreaser or isopropyl alcohol applied with a clean cloth is sufficient to remove any grease or dirt residue from the rim before mounting.
