Extra fine medium traction tyre 1/32

Extra-fine medium traction tyre Tectime: the technical choice for your 1/32 setup

The Tectime reference TT400 is an extra-fine medium hardness tyre designed for the rear axle of 1/32 scale slot cars. Its design addresses a specific need: to provide the appropriate profile for those chassis that require a reduced section rubber without sacrificing the balanced performance that a medium hardness offers in traction.

Compatibility and wheelbase

This tyre is recommended for cars with a wheelbase between 76 mm and 82 mm. This is a key detail: outside of this range, the rubber may not perform under the optimal conditions for which it was designed. Always check the measurements of your chassis before fitting.

Within that wheelbase range, Tectime recommends using:

• Front pulley: at least 6.5 mm.
• Rear pulley: at least 8 mm.

Adhering to these guidelines ensures that the transmission and rolling diameter work in harmony, avoiding unnecessary stress on the drivetrain and ensuring proper contact with the track.

Function and performance

Medium hardness in a traction tyre offers a balance between grip and durability. It is not so soft that it wears out quickly during long sessions, nor so hard that it sacrifices traction on demanding surfaces. The extra-fine profile, for its part, reduces unsprung mass on the rear axle and allows for a more precise adjustment of the rolling diameter, which directly affects the car's response to the throttle.

Fitting and preparation

For a proper fit, consider the following points:

• Ensure that the rear wheels are perfectly centred and balanced before fitting the tyre.
• Once fitted, a light sanding with fine grit sandpaper or a preparation lathe helps achieve ideal concentricity and uniform grip around the circumference.
• Respect the minimum pulley diameters indicated by Tectime to avoid straining the transmission.
• Check that your chassis's wheelbase is within the recommended range (76-82 mm) before choosing this reference.

Common mistakes

The most common mistake with extra-fine profile tyres is fitting them on chassis with wheelbases outside the recommended range, which leads to incorrect rubber performance and below-expectation results. Another common error is not sanding the tyre after fitting, especially if the wheel is not perfectly concentric, resulting in vibration and loss of traction.

Frequently asked questions

What wheelbase is this rubber designed for?

Tectime recommends this reference for cars with a wheelbase between 76 mm and 82 mm. Outside of this range, performance may not be optimal.

What size pulleys should I use with this tyre?

According to Tectime's guidelines, pulleys of at least 6.5 mm should be used on the front axle and 8 mm on the rear within the recommended wheelbase.

Is it necessary to sand the tyre after fitting?

It is not strictly mandatory, but it is highly recommended. Sanding ensures perfect concentricity and uniform grip, resulting in greater consistency in performance.

What type of fitting is it used for: traction or guide?

This rubber is specific for the traction axle, that is, the rear axle of the car. It is not designed to be fitted on the guide or the front axle.

What track systems is the car using this rubber compatible with?

Compatibility depends on the car, not the tyre itself. This rubber can be used on any 1/32 slot car with a wheelbase between 76 mm and 82 mm, regardless of whether it runs on Scalextric, Ninco, Scaleauto, or Carrera tracks, among others.

The Tectime TT400 is an extra-fine medium-compound rear traction tyre for 1/32 slot cars, recommended for wheelbases between 76 mm and 82 mm. Designed for precision fitting with minimum pulleys of 6.5 mm (front) and 8 mm (rear), it delivers a balanced grip-to-durability ratio for club racing and recreational use alike. A reliable choice for slot car preparation enthusiasts looking for the right tyre spec from the first fit.
