Metzeler Racetec RR Racing Tyres
The Metzeler Racetec RR is the ultimate racing tyre. It's the evolution of RACETEC INTERACT, and is the result of direct experience derived from real Road Racing competitions like the Isle of Man TT. In 2014, Metzeler riders stood on the podium 39 times with 16 wins in the major road races. Metzeler have really kicked up a gear when it comes to various racing activities and capabilities and this on the back of the recent launch of the Metzeler Sportec M7 RR. Road racing courses feature multiple and variable conditions and the Racetec RR compound specifications have been developed to cope with all of them. The aforementioned compounds are a blend of polymers and resins with different grades of carbon black to maximise hysteresis- even on slippery surfaces. The front tyre conforms to the micro-granularity of tarmac delivering more grip and wear resistance to last longer on asphalt and give the tyre high flexibility at lower temperatures. As for the rear, a highly conductive centre strip supports the shoulder compound from underneath and warms it up during long straights by distributing the heat generated to the shoulders. If it's the track day tyres you need then focus on the K1 and K2 compounded tyres. If you want that sort of grip, but for Road use, then its the cheaper K3's.
