You may or may not agree with Dave Meyer's time line, but clearly we evolved to this point in time, where 30mm tires are showing up in the pro ranks, because of other concerns besides absolute speed.

Dave Meyer has a good theory. Although my theory is that hookless rim is adopted purely because of light weight (and especially light polar momentum). And wider tire actually does not make blow-off less likely. The way they make tires compatible with hookless, is to make the bead as tight as possible. My pet theory remains that 30mm came hand-in-hand with the mass adoption of tubeless. Sealants are wonderful, but above 40psi, it starts to take longer and longer to seal. Above 60pis it starts to get iffy.
