To get a feel for the Rosso IIIs’ character and capabilities, I set off on a multi-day romp around California. During the following 1,000-plus miles I rode everything from arrow-straight freeways to mountain switchbacks, and throughout it all the Rosso IIIs tracked true and stuck like glue with quick, direct, and linear steering. A pre-dawn departure from Lake Tahoe offered the opportunity to test the tires’ cold grip, which proved to be excellent. Warm-up is rapid, as confirmed by placing my ungloved hand on the tread after only a few miles of riding. Later that day in the Sierra foothills, the temperature spiked to 100 degrees while the road tightened up on itself, and besides a few squirms over sun-softened tar snakes, the Rosso IIIs never strayed from my intended line. The only conditions I wasn’t able to test the tires in was rain, and ironically it poured at the office one of the days I was away.
