I maintained a highway speed of between 140 and 170 kilometers per hour while driving my 205/55 R16-equipped Skoda Octavia 1.8TSI (200 horsepower; 290 Newton-meters). I pushed this rubber to its limits and drove for 40 minutes at 230-245 km/h; it functioned flawlessly throughout, showing no signs of resistance to my every turn, stop, and acceleration. In terms of grip and trajectory retention, this is the greatest rubber I have rode. Nothing is flawless though, as the suspension picks up on the noise and the bumps and joints.
