CLASSIC FRONT 18.5x 9 NO-FRICTION

NSR Classic Front No-Friction Tyres: Less Resistance, More Control

The NSR Classic Front No-Friction 18.5×9 (reference NSR5250) are the specific front tyres for the NSR Classic line, designed with a minimal-friction compound. Their function is not to provide traction — that is reserved for the rear axle — but rather the opposite: to roll with the least resistance possible so that the car responds more cleanly in corners and does not lose speed due to a front axle that brakes instead of supporting.

Function and Performance

In a slot car, the front axle does not provide traction, but it can penalise performance if the tyres offer too much rolling resistance or if their grip unbalances the steering response. NSR's No-Friction philosophy targets exactly that point: a specifically formulated compound to minimise friction with the track, resulting in:

• Smoother rolling on all types of layouts.
• Less resistance that does not rob power from the motor.
• More neutral front-end behaviour, with no tendency to "push" or resist in corners.
• Compatibility with different track surfaces without interfering with the overall balance of the car.

Size and Compatibility

With dimensions of 18.5 mm diameter and 9 mm width, these tyres are tailored to the specifications that NSR sets for its Classic range. Before fitting them, it is advisable to check that the front wheels of your model can accommodate this exact section, as NSR offers various sizes for different configurations in its catalogue.

Fitting and Preparation

The fitting process poses no difficulties for those already experienced in preparing slot cars. Nevertheless, it is important to consider a few points:

• Ensure that the front wheels are perfectly centred and free of adhesive residue or old rubber before installing the new tyres.
• It is not necessary to apply glue on the front axle with No-Friction compounds, unless the fit with the wheel is very loose.
• Once fitted, check that the axle rotates freely without rubbing against the body or chassis.
• If you detect vibration on track, revisit the centring of the wheels with a lathe or fine sandpaper.

Common Mistakes

The most common mistake is using traction tyres designed for the rear on the front axle. This increases resistance, unbalances the car, and can create unpredictable behaviour in corners. No-Friction tyres are designed exclusively for the front axle, and mixing them with high-grip rears is precisely the combination that NSR recommends to maximise the balance of its Classic cars.

Frequently Asked Questions

What is the difference between a No-Friction tyre and a conventional rubber tyre on the front axle?

A conventional tyre can generate rolling resistance and some unwanted lateral grip on the front axle. NSR's No-Friction compound reduces that friction to a minimum, allowing the car to pivot more naturally and the motor not to have to overcome that extra resistance.

Are they compatible with any NSR Classic slot car?

They are designed for the NSR Classic line. Compatibility depends on the diameter and width of the front wheels of the specific model. Always check that your model accommodates the 18.5×9 size before purchasing.

Can they be used on plastic tracks and on wooden or vinyl tracks?

Yes. Being a low-friction compound, their performance is quite consistent on different surfaces, as they are not designed to generate grip but precisely to avoid it on the front axle.

Is it necessary to sand or prepare them before use?

Generally, it is not necessary, but if you want to ensure that the diameter is perfectly uniform and that they roll without vibration, a light pass on the lathe is always beneficial, especially in competitive environments.
