Crossply tyres

On today´s market the crossply tyre is the "classic" design. Its advantages are its simple structure and its sturdy sidewalls, which particularly in off-road use offer many benefits (impact protection). Crossply tyres have a maximum design speed of 240 km/h (150 mph). Material used: usually rayon or nylon fabric.

Typical designation: 4.00 - 18 M/C 64H TL TKH 24

Breaker tyres

The breaker tyre originated from the crossply design, to provide a tread area which was effectively reinforced from the inside, giving the tyre a longer service life through reduced transverse slip and making it less prone to failure. Continental uses this design on its TK 16/17 and Milestone. Material used: usually rayon or nylon fabric. Normally the breaker and casing feature the same material.

Typical designation: 130/90 - 16 M/C 73H TL reinforced TK 17

Bias belted tyre

The bias belted tyre is the precursor of the radial tyre. Whilst the casing is still crossply in design, the tyre features a belt, usually made from Kevlar. The bias belted tyre can be recognised by the B (=bias belted) in the designation on the outside of the tyre.

Radialreifen

Radial tyres feature a casing angle of approx. 90° to the circumferential direction (direction of travel) and a belt angle of 0 - 25° approximately. The belt, located under the tread area, gives the tyre stability and permits far higher speeds, as the centrifugal force deformation is substantially lower. Reduced material thickness in the sidewall section means the tyre heats up less and the high speed strength is further increased.

In terms of riding dynamics, modern motorcycles are geared to radial tyres. As an example: a 4.00 - 18 M/C 64H TT Conti TKH 24 tyre "grows" by approximately 2 cm on average at a speed of 210 km/h (131 mph), whereas a comparable radial tyre only ex-pands by a few millimetres. The radial tyre can be recognised by the R in the designation on the sidewall of the tyre.
