So, racers can save another foot by taking a good one in the morning?
Similarly in terms of extreme marginal gains, the optimum tire pressure for racers depends on the tire, road surface, temperatures, and the rider's weight.
The only real mistake is going too high in pressure. I was running 90 psi on 25 mm GP5000 TR S yesterday on good roads. Then, I got to some nasty chip seal that was rattling my feeble brain. So, I recursively let out a little air until it felt comfortable. What a difference. I got home and measured 75 psi rear and 65 psi front. Normally on crappy roads, I just do 75 psi.
