Road Bike Tire Pressure Recommendation
Another good starting place is frank berto s recommendation to choose a tyre pressure that involves a tyre being compressed 15 of its height under the rider s weight.
Road bike tire pressure recommendation. 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. I would guess that for you ideal inflation pressure would be 80 90 psi but this may vary depending on your roads riding style and the balance between comfort and performance you find ideal. 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. Since your tire is your contact point to the road maintaining the proper pressure determines the handling and performance of the bicycle which in turn impacts your speed and your ability to.
So there is not a single simple number formula or other type of one size fits all answer. If your recommended tire pressure is near the maximum pressure rating for the rim we recommend moving up in tire volume. Road tires typically require 80 to 130 psi pounds. For example 90psi in a 25mm tire will feel the same as roughly 70 psi in a 28mm 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. Remember as tire size and therefore volume increase you can decrease tire pressure. The recommended tire pressure psi for a bicycle.
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. The best tire pressure to use is a subject of much debate. Proper tire pressure lets your bike roll quickly ride smoothly and avoid flats narrow tires need more air pressure than wide ones. So my recommendation for 28mm tires is to experiment with various pressures until you find the sweet spot for your road surfaces and riding style.
