All our technical knowhow is working together in harmony to inspire you to play harder. Wider Rim Profile- Their research, testing and practical experience shows that wide tubular rim profiles (WST) and wide tire rim profiles (WSR) improves tire performance in comparison to traditional narrow rim profiles. Vittoria wheels are designed to benefit from this improvement. The tread contact area is shorter and wider, so the tire grips and handles better in corners. In addition the tire casing (clincher and tubulars) deforms less, making the tire faster because of lower rolling resistance.
