Not necessarily. Lots of factors go into the "speed" of a tire. And you might find that 25mm tires give you a lot more comfort and durability. Your weight and max psi don't correlate. Max psi has to do with the tire construction, just like the rolling resistance.Originally Posted by ACiveE
Over-inflated tires are susceptible to gashes and have a harsh ride. Under-inflated tires are susceptible to pinch flats.

Many thanks!
So how close to max psi should you go? My calculated psi is like 110psi and the max for the particular tire is 120. Should I have gone with a higher rated(?) tire?
...this is all too complicated. I just want to get on my bike and riiiiiide!

PW,
Your chart is super! I have always wondered what inflation amount I should use. I always heard that I should make them 100-110 to avoid flats but based on "the chart", I should be about 96, so though 100 is close to it, I am often just "pumping up" and go to 110 or 115. I guess I will use the 100 and see how it goes.
Thank you so much for this very informative piece of information.
I love this forum!!!
