Further info: The rim where the Pro One 25c tires are mounted on is 19c internal and at 90psi they are 28.5mm wide. The Pro4s are mounted on 17c wheels, becoming 27mm at 90psi.
May I ask why you run the tubeless at 90 psi .. if comfort is you goal? Your pics represent your subjective analysis of the ride .. not from any real world data?
FWIW ... S1 tubeless 25's are 24.9 on 13-14mm internal rims.
What sort of data would be real world compared to me riding on my tires?
The idea I have been considering is some kind of electronic device mounted on the seatpost or handlebar to record data. How too... ? Subjective data is just that... no hard fact.
I see. It is not in my interest to spend that sort of time or effort into finding things that I like. While I do appreciate and am very grateful for those who do spend the time and effort into providing objective evidence for their respective communities, I find myself unable and unwilling to do that. Why? Because I like to enjoy some things in life in the most personal and subjective way as possible. I enjoy cycling in the same way I do music. I go up to certain extent, but never dig into it so deeply so as to find marginal gains or chase the very last gram at any cost. On my hobbies, I do as much as I please. It is only in my professional life that I focus on gaining that marginal advantage technically. There, I can, invariably, spend a lot of time being as objective as I need to be.
Don't take my "graphs" too seriously. As I said, the way I feel the tyres is the way I feel them and that was the best way I found to communicate what I perceive. No attempt into giving anyone the impression that those are the ultimate proof that Durano Pluses are steel-like.
Obviously Miller finds the Pro Ones comfortable at around 75psi. I find them comfortable too but I am just not enjoying that sort of feedback they give. And if you speak about comfort being the objective, I can tell you that comfort can only be very subjective. Is saddle A more comfortable than saddle B? Only your bottom can tell!! How about a lower staddle height or a flat bar vs a drop bar? Maybe the Eames chair is not comfortable at all because the Ikea's Oakloem is the best thing you can sit your body on. As you noted, this is just me talking about me and I'd love to hear from all of you to get your impressions and experiences.
Once I got the compass more or less aiming in one direction, I go ahead and take the wallet out.
Sometimes there are no definite answers (like in this case and the other thread I have asking about the Vredesteins) so the best thing I got is my current experience with 5 different tyres, the words of the people around here, and the willingness to try a couple of sets and see how I get along.
