Roadmaster Bike: Bicycle Tyre Pressure Calculator

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.

Correct tyre pressure for road bikes. As with most subjects, finding the correct tyre pressure for a road bike can be turned into a science. The tyre type, the weather conditions, the intended use and the weight loaded onto the tyres, are all important factors to consider. It is important to realise that the weight of the rider plus the bike plus any other equipment and clothing all add up.

Bicycle tyre pressure calculator. 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. These two extremes, however, represent only the upper and lower pressure limits; for standard trekking wheels, the most frequent choice would be a. Editor’s Note: We have often cited articles or research from Bicycle Quarterly in these pages, and most recently we’ve been following, with particular interest, their studies on tire pressure.Coach Fred Matheny has referenced that research in his recent reviews of the new, wider tires from Rene Herse Cycles (previously known as Compass Bicycles), a BQ sister company. The importance of choosing the right tyre pressure is that it helps to protect the tyre against punctures, minimise rolling pressure, enables you to ride smoothly and to have some degree of comfort. Now, air pressure pumped into a bicycle is measured by PSI, which means Pounds per Square Inch.

Bicycle tyre pressure is an important part of bicycle maintenance, handling and safety. This article discusses some basic guidelines for tyre inflation. How Much Pressure Road Bike Tire Should Have. Proper tire pressure allows your bike to move smoothly and quickly as well. Here are air pressure requirements for different types of bikes: Road bike tires are narrowest and require between 80 and 130 psi air pressure. Mountain tires are flatter and they need an air pressure between 30 and 50 psi. road bicycle tire pressure calculators using Jan Heine 15% drop and Michelin chart methods. Road Bicycle. If calculated pressure exceeds tire’s rated maximum, choose a wider tire. If calculated pressure is below tire’s safe minimum, choose a narrower tire.. Calculator obeys the chart’s min/max pressure limits.

Road/Tri Bike Tire Pressure Calculator. The best tire pressure to use is a subject of much debate. The factors that influence the ideal tire pressure are: your weight, the bikes weight, tire size, weight distribution, and rider preferences. So there is not a single simple number, formula or other type of one size fits all answer. The pressure calculator was created by Dave. two top bicycle science guys, the most efficient bicycle tire pressure is one that gives you a 15% drop in tire height when you get on the bike. “This tire has too little air!” It’s squishy and hard to turn.. Doing the Maths the 26″ tyre should be about 15% higher pressure than the 700C. Since there’s no single pressure that will work for every rider, Silca has taken that pressure knowledge and packaged it into an online tire pressure calculator that you can use, for free. The most basic form is the LITE version which limits you to inputs for the total system weight (rider + bike + gear), and the measured tire width.

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. Here’s a graph of his recommendations, showing the relationship between pressure and wheel load for each common road bike tyre size. The correct tyre pressure guide . The best tyre pressure for your bike will depend on the kind of bike you have, the kind of tyres you have fitted; and also factors like rider weight, road conditions and weather conditions. Mountain bike tyre pressures . Mountain bike tyres are run at a lower pressure than road tyres so that the tyre can. Thanks to the higher pressure I don’t have many flats and don’t have the need to install tire inserts. Felix Stix 92 kg. I often wish I could run lower pressures or lighter tires. However, the ugly truth is that with my weight and riding style there is no real sense in running “trail-oriented” casings. I have to opt for heavy enduro.

Under load, a tyre flattens until it presses against the road surface with the force of the weight it supports, so a tyre supporting 100lb at a pressure of 100psi will have a contact patch area of one square inch. As the tyre rolls along, the contact patch moves around its circumference, flexing the tyre as it moves. You need to enable JavaScript to run this app. SRAM | AXS. You need to enable JavaScript to run this app. The PSI Calculator will give you both the front and rear PSI for your bike tires.

If you’re new to biking and testing your tire pressure, the PSI Calculator especially is a great replacement for a gauge.

Pump it up. Proper tire pressure lets your bike roll quickly, ride smoothly, and avoid flats.Narrow tires need more air pressure than wide ones: Road tires typically require 80 to 130 psi (pounds. Having read the debate about 23 v 25 tyres I found a tyre pressure calculator which tells you what you should be running based on 15% tyre drop: Having read the debate about 23 v 25 tyres I found a tyre pressure calculator which tells you what you should be running based on 15% tyre drop: Toggle navigation.
