2 G25 slick F1 rear tyres 18 (17.3mm) x 4

Policar G25 slick rear tyres: grip and precision for your F1 18 in 1/32 scale

Policar is one of the leading brands in the world of competitive slot racing, recognised for the quality of its 1/32 scale Formula 1 cars and for offering a specific spare parts catalogue that allows each model to be maintained at its optimal level. These G25 compound rear tyres are the official replacement for the F1 18 model, and come in a pack of 4 units.

Function and performance

The G25 compound is a medium-soft rubber, aimed at providing a good balance between grip and durability on Scalextric or Ninco track types, as well as on Sport tracks (Scaleauto, Slot.it). The slick tread —without pattern— maximises the contact surface with the track, resulting in greater traction on acceleration and increased stability in fast corners.

With a diameter of 17.3 mm, these tyres fit directly onto the rear wheels of the Policar F1 18 without the need for adaptation or prior sanding, although as always in slot preparation, a proper truing after installation ensures maximum concentricity.

Compatibility

These tyres are specifically designed for the Policar F1 18 cars in 1/32 scale. Before installing them on another model, check that the tyre measurements match those of your car's wheels, as Policar offers different references for its various versions.

Installation and preparation

• Carefully remove the worn tyres to avoid damaging the wheel.
• Fit the new tyres ensuring they are seated evenly across the wheel.
• If you are looking for maximum performance in competition, pass the axle through a lathe or grinder to ensure all tyres rotate at the same height.
• Avoid excessive use of glue: the tension from the tyre on the wheel is usually sufficient, or a minimal amount of fine cyanoacrylate if necessary.

Common mistakes

• Fitting the wrong tyre: make sure to check the specific reference for your version of the F1 18, as there are variants with different measurements.
• Not truing after installation: even new tyres can have slight eccentricities. A basic truing makes a difference in track performance.
• Mixing compounds on the same axle: if you change only one tyre, ensure both are of the same compound to maintain traction balance.
