Are wider road bike tires faster, or is 28mm still the sweet spot?
This one runs on wind tunnel numbers, rolling-resistance testing, and the engineering data dobes behind tire pressure, not marketing and feel.
In this video we break down aerodynamic drag across 28, 30, 35, and 40mm tires, why the gaps are tiny at endurance speeds and elclasico only start to matter at race pace, why a 30mm tire can roll faster than a 28, the impedance breakpoint bc rcmp snowmobiler search that makes over-inflated tires feel fast while actually slowing you down, why smooth-lab results flip on rough roads, the rule of 105 and matching tire width to modern wide rims, tire weight and the rotating-weight myth, nominal versus measured width and why your 28 is probably really a 30, and how the pro peloton went from 28mm to 30-32mm and then partway back again.
