What Psi Road Bike
What pressures are appropriate for 28mm road bike tires.
What psi road bike. There was a time when most riders would opt for 23c tyres on the road pump the tyre pressure up to around 110psi for every ride letting out just a little air to provide extra grip in poor weather. The recommended tire pressure psi for a bicycle. A lot of riders are taking advantage ofthe increased comfort of wider tires. The road bike tires need to run at high pressure to reduce the chances of a pinch.
Tire pressure of the road bikes. If you use tubed tires that are between 2 35 and 2 4 inches the pressure per tire should be 29 psi. It is 26 psi on the front and 28 psi on the rear for the tubeless tires. For example if a 165 pound rider uses 100 psi on his road bike a 200 pound rider should run closer to 120 psi and a 130 pound rider could get away with 80 psi.
I run the rear tire 10 psi below the max and the front tire 15 20 psi below the max. There doesn t seem to be any performance loss and on rough roads speed is often faster because the wider tires absorb the bumps and roll over them with little loss of forward speed while in contrast narrow tires with high pressures bounce and retard speed. That includes fairly objective measurements with a power meter. In drizzly or rainy weather also lower the pressure by 10 psi for improved traction.
A lower pressure will provide a smoother ride better tire adhesion on the road and better control. Over inflated tires fail dramatically and often sound like a gunshot. Mountain tires are flatter and they need an air pressure between 30 and 50 psi. On a new smooth road your best tire pressure might be 100 psi but bring it down to 90 psi for a rough road.
Tire pressure is crucial for safety in cars and bicycles are no different. If you re riding a mountain bike instead of a road bike the tire pressure is not going to be the same. We all dream of that mystical ride along a beautiful winding country road paved with new asphalt. If your bike has hybrid tires you d have to maintain the air pressure between 50 to 70 psi.
When i made that transition from running at max i noticed a lot more comfort and no loss of speed or efficiency. 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. For every 5kg over 70 kgs of the rider you need to add 1 psi. Road bike tires are narrowest and require between 80 and 130 psi air pressure.
According to enduro mountainbike magazine the psi varies if you have tubed or tubeless mountain bike tires.
