25mm Road Bike Tyre Pressure

Here s a graph of his recommendations showing the relationship between pressure and wheel load for each common road bike tyre size.

25mm road bike tyre pressure.

These two extremes however represent only the upper and lower pressure limits. Proper tire pressure lets your bike roll quickly ride smoothly and avoid flats narrow tires need more air pressure than wide ones. Another good starting place is frank berto s recommendation to choose a tyre pressure that involves a tyre being compressed 15 of its height. For example 90psi in a 25mm tire will feel the same as roughly 70 psi in a 28mm tire.

Tyre drop is hard to measure but berto did a shedload of measurements and plotted the pressure needed to give a tyre drop of 15 percent for a range of rider weights and tyre widths. Cyclist s guide to road bike tubeless. So you can see the tyre pressure is much lower than with an inner tube but it offers a 29psi range to allow for the aforementioned variables like rider bike weight riding style and road conditions. 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.

Road bike tyres are run at a higher pressure than mountain bike tyres to reduce rolling resistance and the chance of pinch flat punctures. Generally though for road use you want a slick tyre or a tyre with minimal tread with a flexible casing inflated to a high but not too high pressure. Rolling resistance does vary slightly with tire pressure but it s not linear and it depends on the surface. Road tires typically require 80 to 130 psi pounds.

For standard trekking wheels the most frequent choice would be a. On smooth surfaces like the one used in the tests shown above moderately high tire pressure say 100 110 psi for a 25 mm tire actually rolls slower than either a lower pressure 80 psi or a higher pressure 130 psi. 90psi 6 2bar front 93psi 6 4bar rear.

Suggested tyre pressure for road bike tyres 25mm for a 70kg rider. Comparing rolling resistance a 25mm tubeless tyre at 95 100psi is the same as a 30mm tubeless tyre at 72 80psi see related best tubeless road tyres 2020. Remember as tire size and therefore volume increase you can decrease tire pressure.
