Conventional wisdom on bicycle tires has held that smaller is better. Smaller tires were supposed to be lighter, more aerodynamic and have lower rolling resistance. Then came science. Research has shown that a larger tire has the ability to cut rolling resistance, making you faster than you would be with a traditional 23c-wide racing tire. And of course, a larger tire offers improved grip in dry and wet conditions. In some cases, when using the right rim, a bigger tire also can improve aerodynamics. Let’s not forget that comfort gets a big upgrade as well.
