Bicycle Wheel Pressure Bar

To determine the right pressure you ll need to measure the load on each wheel.

Bicycle wheel pressure bar. Tyre pressure is a critical measurement for getting the most out of your mountain bike. According to enduro mountainbike magazine the psi varies if you have tubed or tubeless mountain bike tires. These two extremes however represent only the upper and lower pressure limits. 38psi 2 6bar front 40psi 2 75bar rear.

50psi 3 4bar front 55psi 3 8bar rear. When running at continuous maximum speed the pressure in the front wheel should be increased by 0 2 bar. For standard trekking wheels the most frequent choice would be a tyre pressure between 3 and 4 bar. A thin road tyre would have 6 8 bar of pressure much like a road bike have a look at our tyre pressure calculator for road bikes while for a fat bike tire a pressure of 0 5 bar will suffice.

The other is that wheel load is per wheel. 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. A hybrid bike tyre is similar in volume to a cyclocross tyre so the pressures are also similar. There are a number of variables that go into figuring out the ideal pressure range for a bicycle tyre such.

Put a bathroom scale under. Tommaso has some simple advice to get started on your ideal tyre journey if you used to ride 116 130 psi 8 9bar on a 23mm tyre you might want to drop pressure in a 25mm tyre by 1bar 14 psi. For tubeless tires that are the same size the pressure should be slightly lower just 26 psi. The rear wheel carries more of the load usually between 55 and 65 percent.

The more you weigh the higher your tire pressure needs to be. For a 700 x 23c tyre on the road a 55 kg rider should start with 100 psi while a 90 kg rider should run closer to 120 psi. If you weigh 72kg and your bike weighs 8kg then your tyres carry a total of 80kg but it s not evenly distributed. For 700 x 25c tyres minus 10 20 psi.

Remember never go above or below the manufacturer s recommended pressures. The owner s manual states that the front wheel should be inflated to 2 3 bar and that the rear wheel should be inflated to 2 5 bar with one rider and 2 9 bar with two riders.
