Road Bike Psi Chart

For standard trekking wheels the most frequent choice would be a tyre pressure between 3 and 4 bar.

Road bike psi chart. What pressures are appropriate for 28mm road bike tires. The world s best bike if the wrong size for you won t make you a better rider. According to enduro mountainbike magazine the psi varies if you have tubed or tubeless mountain bike tires. The amount of weight that will be exerted on the tires does play a crucial role in how much pressure you will put on a tire.

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. Mm inflate to psi weight of fully dressed rider bike rider bike lb. 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. Bike sizing getting the proper size bike is key to comfort performance and safety.

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. Rider bike lb. If you use tubed tires that are between 2 35 and 2 4 inches the pressure per tire should be 29 psi. These two extremes however represent only the upper and lower pressure limits.

If you re riding a mountain bike instead of a road bike the tire pressure is not going to be the same. F r weight distribution 40 60 45 55 front tire width 20 23 25 28 32 37 mm inflate front to psi rear tire width 20 23 25 28 32 37 mm inflate rear to psi. 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. A lot of riders are taking advantage ofthe increased comfort of wider tires.
