Tyre 19x10.5mm (shore 25)

Grip and precision in every corner with the Scaleauto A-S25 tyre

The Racing Slick SC-4752AS25 tyre from Scaleauto is a component designed for enthusiasts and competitors who demand the best from their rear axle. With a Shore 25 hardness, it falls within the soft rubber range, resulting in a greater effective contact patch and a more immediate response to the track surface.

Function and performance

The slick, treadless profile maximizes the contact patch with the track. The Shore 25 compound provides notable grip, especially on well-prepared plastic or wooden circuits. This level of softness is common in competition setups where immediate grip is prioritized over tyre longevity.

Compared to higher hardnesses (Shore 35 or Shore 45), Shore 25 offers more grip in low-speed sections and tight corners, although it may show greater wear in long sessions or on abrasive tracks. It is a frequent choice in club and competition setups where fine-tuning makes the difference.

Compatibilities and fitting

This tyre is designed to be fitted on wheels between 15.8 and 17 mm in diameter. Before installation, it is advisable to check the outer diameter of the wheel to ensure a correct fit without play or excessive tension that could deform the profile.

Once fitted, it is recommended to true the tyre on the car itself to guarantee perfect concentricity with the axle. This step is especially important with soft compounds, where any eccentricity is more noticeable on track.

Common mistakes when working with Shore 25 tyres

• Fitting without truing: even if the tyre appears round to the naked eye, fine truing removes small irregularities that affect stability.
• Incorrect storage: soft rubbers are sensitive to UV light and heat. Store them in a sealed bag and away from heat sources.
• Using on dirty tracks: a track with dust or silicone residue drastically reduces the performance of a soft tyre. Cleaning the circuit before racing is essential.

Ideal for…

This tyre is especially well suited for slot competition cars mounted on Scaleauto chassis or similar, where maximum rear axle performance is sought. It is also a good option for enthusiasts who want to experiment with different hardnesses and find the balance between grip and wear on their usual circuit.

Frequently asked questions

How many units are included in the package?

The information provided does not specify the number of units per package. We recommend checking the product description or contacting us before ordering if you need confirmation.

Is it compatible with wheels from other brands besides Scaleauto?

The tyre is compatible with any wheel whose outer diameter is between 15.8 and 17 mm, regardless of the manufacturer. Always check the exact size of your wheel before fitting.

What is the difference between Shore 25 and other hardnesses?

The lower the Shore number, the softer the rubber. A Shore 25 provides more grip than a Shore 35 or Shore 45, but it also wears out faster. The choice depends on the type of circuit, car setup, and competition format.

Do I need to true the tyre after fitting?

Yes, especially with soft compounds like this. Truing ensures the tyre rotates perfectly concentrically, which improves stability and real grip on track.

Is it suitable for official competition?

It depends on the specific regulations of each championship or club. We recommend checking your category's rules before choosing the tyre hardness.
