Road bicycles like the ones used in the Tour de France use pressures in the 120-140 psi range, but cars generally float around the 32 psi area.
Tops on my trucks is 44
Trucks often 60-100 though
Yep, 60/80 PSI on my work truck, but the tires are 12-ply.
Go to the truck stop and use the big rig hose. You'll get what you want 🤯
Probably less these days as it’s shown lower pressures and larger tires can improve performance.
Which type of performance? Surely not fuel economy/emissions?
Yes fuel economy. Energy expended per distance traveled or power needed to maintain a given speed. Just the fuel in this case is burned by your own body.
At world class levels, a few watts here and there will make a big difference by the end of a race.
