25mm Road Bike Tyre Pressure

Proper tire pressure lets your bike roll quickly ride smoothly and avoid flats narrow tires need more air pressure than wide ones.

25mm road bike tyre pressure. Road bike tyres are run at a higher pressure than mountain bike tyres to reduce rolling resistance and the chance of pinch flat punctures. Road bike tyre pressures. 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. 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.

Road tires typically require 80 to 130 psi pounds. 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. For example 90psi in a 25mm tire will feel the same as roughly 70 psi in a 28mm tire. Cyclist s guide to road bike tubeless.

The best road bike tyres in 2020 as. 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. Another good starting place is frank berto s recommendation to choose a tyre pressure that involves a tyre being compressed 15 of its height. 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.

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. Here s a graph of his recommendations showing the relationship between pressure and wheel load for each common road bike tyre size. 90psi 6 2bar front 93psi 6 4bar rear. For standard trekking wheels the most frequent choice would be a.

These two extremes however represent only the upper and lower pressure limits. Remember as tire size and therefore volume increase you can decrease tire pressure. Rolling resistance does vary slightly with tire pressure but it s not linear and it depends on the surface.
