Road Bike Tire Pressure 28mm

28mm tire pressure what s your magic number.

Road bike tire pressure 28mm. 5 things you should know about tire pressure this is why a couple of years ago road bikes started appearing in shops with stock tires measuring 25mm instead of 23mm. Remember as tire size and therefore volume increase you can decrease tire pressure. 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 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. 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. I ve just spooned some 28mm conti gp4000 s on my road bike s mavic open pros. Let s say you re a large 240 to 250 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. 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. Rider rather than run a 28mm tire at 70 80 psi on your set of ses ar wheels you should consider running a 30 32mm tire. What pressures are appropriate for 28mm road bike tires.

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. A lot of riders are taking advantage ofthe increased comfort of wider tires. 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.

I m 180lbs usually run 90 100 100 110psi f r on 25mm s condition dependent. At the 15 tire drop air pressures which are very close to the recommended air pressures for a given size the tables are turned and a bigger road bike tire will have a higher rolling resistance. Road tires typically require 80 to 130 psi pounds.
