Tire Pressure On Road Bike

For example on my touring bike when not loaded and just my body weight and bike weigh calculated using 32 wide tires i use 45 psi front and 70 rear but if i add 55 pounds of gear for touring i now have to raise that psi to 60 f and 90 r.

Tire pressure on road bike. For every 10 degree drop in fahrenheit temperature your tire pressure drops by 2 percent such that a drop from 80 to 50 degrees translates to a drop of 100 to 94 psi. Road bike tyre pressures. 90psi 6 2bar front 93psi 6 4bar rear. Road bike tires are narrowest and require between 80 and 130 psi air pressure.

On a new smooth road your best tire pressure might be 100 psi but bring it down to 90 psi for a rough road.
