Re: Optimal Tire Pressure for High Speed Riding
Don't exceed what it says on the side of the tire. If 40 is the max, don't go over 40psi.
Over inflating the tire above the manufacturer's recommendations is not wise or safe. If mine says, 45 max inflation I keep them at 40. That's a 5 psi margin for gauge error and hot pavement. Treat you bike tires like you would your car tires. You wouldn't over inflate them. Same principle.
