For as long as I can remember I have heard and read that the higher the air pressure in a bike tire the better it will roll … meaning faster because of less rolling resistance. Along with this it was believed that narrower tires do better than wider tires when it comes to the speed they are capable of. Well, now it has been proven that this is false. Yep, now they are saying that we can run wider tires and at lower pressures without encountering a reduction in the speed we can obtain as well as the effort needed to propel ourselves along at those speeds. HERE is an article about this subject written by Jan Heine on his blog.
Personally I have a difficult time accepting this. My own experience is that the same tire at a lower pressure rolls less easily than it does at a higher pressure. I can detect a lot of difference between the pressure as it takes more effort to pedal and I can’t go as fast when the pressure gets down too low. And I am talking about staying within the minimum and maximum pressure rating. It really is difficult to argue against scientific studies, but I am not buying into this just now.
