METZELER presents the Roadstec Z8 Interact motorcycle tyre:

• The tread pattern maximises flexibility, ensuring an optimal contact patch in all conditions.
• The 3 tension zones of the Interact technology provide better longevity and good grip in corners.
• A new high-silica compound with nanoparticles ensures performance and safety in all weather conditions.
• The rear tyre in (M) and (O) versions features a dual-compound.
• The compound of the central section of the tread, depending on the tyre size, is on average 45 mm wide, with a silica content of 70% specifically designed to optimise mileage and high-speed stability.
• The ends of the tyre have a zone of approximately 88 mm on each side of the profile with a 100% silica compound, significantly increasing grip on wet roads and preventing slips in any conditions.
• The front tyre is also made from a 100% silica compound.

Handling, braking, comfort... Choosing a motorcycle tyre impacts many aspects of your machine's behaviour, both on the road and on the track or off-road. It is therefore essential to carefully select the model best suited to your needs.
To help you gain clarity, here are some explanations to help you decipher the information on motorcycle tyres:

• Dimensions: tyre width in millimetres and height of the tyre as a percentage of this width. E.g.: 190/55, for 190 mm wide and 55% high
• Structure: radial (ZR, or R) or diagonal (B), both tyres must be identical in this criterion
• Diameter: expressed in inches, e.g. 17 or 19
• Load index: maximum load the tyre can support
• Speed index: maximum speed the tyre can support
• M/C indicator: tyre purpose, M/C for motorcycles
• With or without inner tube: TL ("tubeless") for tubeless tyre, TT ("tubetype") with inner tube

In specific cases, other mentions may appear, generally associated with the commercial name of the tyre. Here are a few:

• A: Kawasaki
• C, F or GT: BMW specification
• E or B: Special carcass for heavy or loaded motorcycles
• G: Specification for Honda, Suzuki, Yamaha
• GTW: Heavy, fast, and powerful Grand Touring motorcycles
• H: Original Honda specification
• K: Very fast motorcycles
• M: First fit for Suzuki
• N: For Aprilia, Honda, Ducati, Kawasaki, Suzuki, Yamaha, Triumph
• RF: Reinforced tyre
• WW: White-walled tyre

Other less significant references also appear on the sidewall of motorcycle tyres (country of manufacture, DOT marking, etc.)
Remember to regularly check your tyre pressure, as it ensures longevity and superior performance!
