One of the cycling issues I’m kinda frustrated with – especially given the amount mathematical brain power orbiting around and within cycling – is there is no, single calculator that can give you an optimal front/rear tire pressure recommendation for asphalt based on tire width, internal rim width a…

I’m listening to this podcast – literally – right now :slight_smile: That is what inspired the post . . . None of his info (at least so far) has taken into account ‘internal rim width’ - which is a significant aero component…or so I’ve been told.

The actual pressure you’ll need will depend on the quality of your asphalt. If you’ve got a perfect new road, run higher. If you’re running on an old janky stretch of road, run less. It also matters if you care more about max cornering speed, or max straight line speed. Most of the time, people seem…

External rim width might be the more important factor for aero dynamics?

[image] roflsocks: I would love to see a comparison between otherwise identical setups, but over a smooth and rough set of road, to really quantify how much of a difference there is at various setups. There’s a good graphic in the thread I linked to… [image] [image] Using d…

As @roflsocks says there can be no right answer go any given setup as a large part depends on the surface being ridden on. A higher pressure would be better on a track surface than rough tarmac even with the same tyre/tube/rim combo. Aero is a different matter. A good rule of thumb is that the rim …

The rule of thumb as I understand it for road racing is if you’re getting pinch flats because of how little pressure you’re running… you’re too low. Otherwise you’re too high.

[18%20PM] Try these pressures. It works for me. Paraphrasing Josh Poertner " Think smooth not fast when evaluating tire pressure…" A hidden benefit of lower pressure is increased comfort which can contribute to more speed. Max

Have you tried the MyMavic app for iOS? It has a tyre pressure calculator.
