RT Zero grip tyres 15x8mm

Scaleauto RT Zero Grip: control and consistency in every corner

The RT Zero Grip tyres from Scaleauto (ref. SC-4743) are made of rubber and designed to provide a moderate and predictable level of grip, ideal for those seeking balanced behaviour rather than maximum raw traction. With a size of 15x8mm for the rear axle and 13mm wide for the front mounting, they meet the need to fit a specific rubber at each end of the car.

Main features

• Rear size: 15x8mm
• Front size: 13mm (width)
• Material: rubber
• Reference: SC-4743
• Manufacturer: Scaleauto
• RT Zero Grip profile for controlled and progressive grip

Function and performance

The term Zero Grip does not imply a lack of traction, but rather a deliberate reduction in grip compared to the stickier compounds in the Scaleauto range. This translates into smoother and more manageable driving, with less tendency for sudden oversteer. It is a common choice in club setups where the aim is to equalise performance among drivers or during chassis tuning and development sessions.

The difference in width between the rear tyre (8mm) and the front (13mm) corresponds to specific configurations of some chassis where the front end requires a wider rubber to improve guide and stability on corner entry.

Compatibility and mounting

As a spare part from the Scaleauto range, they fit naturally into the models and chassis of the brand that specify this size. Before mounting, it is advisable to check the inner diameter of the tyre to ensure it fits correctly on your vehicle's rims. A well-centred mount and subsequent fine sanding ensure the best concentricity and the most homogeneous behaviour possible.

Mounting and preparation

• Mount the tyres on clean, grease-free rims to ensure good adhesion.
• A light sanding with fine sandpaper on a flat surface removes any irregularities and improves concentricity.
• Avoid contact with solvents or lubricants on the tread: they alter the compound and grip.
• Replace the tyres when they show uneven wear or loss of shape, as they directly affect the stability of the car.

Ideal for…

• Drivers who prioritise lap consistency over maximum grip.
• Club configurations where the aim is to balance performance among participants.
• Chassis development and tuning sessions where a neutral compound facilitates reading the car's behaviour.
• Setups on Scaleauto chassis that specify the size 15x8mm / 13mm.

Frequently asked questions

What is the difference between the RT Zero Grip tyres and other Scaleauto compounds?

The Zero Grip compound offers less adhesion than the high-grip references in the Scaleauto range. This facilitates more controllable and predictable driving, especially useful in tuning sessions or in competition formats where the aim is to equalise performance among cars.

Are the 13mm always mounted on the front axle?

According to the information from reference SC-4743, the 13mm size corresponds to the front tyres. However, always confirm compatibility with your chassis rims before mounting.

Is it necessary to sand the tyres before use?

It is not mandatory, but gentle sanding on a flat surface improves concentricity and eliminates potential imbalance points, especially in competition-oriented setups.

What rims are they compatible with?

They are tyres from the Scaleauto range, so they are designed to fit the rims of that brand with the corresponding inner diameter. Always check the inner size before ordering if you plan to mount them on rims from another manufacturer.

When should they be replaced?

When they show uneven wear, loss of circular shape, or a noticeable reduction in expected grip. A tyre in poor condition directly affects the stability and predictability of the car.

Scaleauto RT Zero Grip tyres 15x8mm (ref. SC-4743) — rubber slot car tyres with a controlled grip compound, available in 15x8mm rear size and 13mm front width. Designed for balanced and predictable handling on the track, these tyres are a go-to choice for club racing setups and chassis development sessions where consistent performance matters more than outright traction. Compatible with Scaleauto chassis and rims specifying this size.
