Metzeler Sportec M7 RR
METZELER has introduced a new supersport tyre – the Sportec M7 RR, which it claims offers the highest levels of handling and safety, even on wet, rough and dirty asphalt.
Introduced to replace the existing Sportec M5 Interact, the new Sportec M7 RR is said to offer up to 20 percent greater mileage.
Metzeler’s Sportec M7 RR tread features a groove layout designed to provide grip in the dry, while at the same time offering water drainage and excellent cornering stability. To achieve this the longitudinal grooves are interrupted by elements of the compound to improve the stability of the tread, the regularity of wear and increase the thrusts in acceleration. These elements are also said to contribute to maintaining the grooves well open when the tyre is in contact with the road to drain water.
In the lateral grooves, the depth decreases gradually towards the shoulder area to increase the compactness and the lateral thrust when cornering at maximum lean angle in the dry; their width, on the contrary, increases towards the shoulder area to ensure an effective drainage of the water at a high angle of bend.
Metzeler has developed a new range of compounds for use in the Sportec M7 RR. The front tyre is mono compound with 100 percent silica. The rear is dual compound, where the shoulder has a 100 percent silica to provide chemical grip on both dry and wet surfaces, supported by a harder compound in the substrate for high levels of stability and cornering precision.
The radial carcass of the new tyre is composed of a special version in rayon. The structure is claimed to be much more rigid and able to maintain its shape under conditions of greater stress and deformation from the load, and above the radial structure is a 0-degree steel belt with Metzeler’s ‘Interact’ technology with different tension zones that offers a progressive behaviour at every lean angle.
The Metzeler Sportec M7 RR is available in the following sizes: 110/70 ZR 17 M/C 54W TL, 120/60 ZR 17 M/C (55W) TL, 120/70 ZR 17 M/C (58W) TL (M), 150/60 ZR 17 M/C 66W TL, 160/60 ZR 17 M/C (69W) TL, 180/55 ZR 17 M/C (73W) TL, 190/50 ZR 17 M/C (73W) TL, 190/55 ZR 17 M/C (75W) TL, and 200/55 ZR 17 M/C (78W) TL.
