By incorporating specially-ramped divots in the shoulder of the otherwise normal road bike tire tread, DT Swiss says the spinning tire itself can supplement the ‘sailing effect’ that they have shown significantly reduces drag in high-end aerodynamic wheels. Now, in a much simpler and lower-cost product – an aero tire can likely provide even more reliable aerodynamic gains… DT Swiss aero road tire concept patent
c. DT Swiss Filed together with aero expert Jean-Paul Ballard of Swiss Side , who has worked on all of DT Swiss’ aero-optimized wheels since their ‘ Road Revolution ‘ back in 2016, these new tires have been refined down to a simple design with a relatively small number of aero depressions in their shoulders that have demonstrated significant aerodynamic benefits in the wind tunnel.
Key to DT Swiss’ description of this patented aero tire tech, is that it’s more consistent than you typically see with aero wheels AND it is equally as highly effective at the lower speeds that most amateur cyclists actually ride (while still maintaining high efficiency at high speeds, too.) at 30km/hr, sailing effect (negative drag) is only achieved with DT Aero Tire (40) vs. 3 competitor tires of the same size (50, 60 & 70) on the same aero wheel Specifically, with average speeds of 37.5km/h, according to the invention a sailing effect can already be utilized in many situations, wherein air impinging obliquely […]
