You bring up good points.
1. Higher mass will slow you down climbing, but the question is how much.
Realistically, the differences are very small. We tested a 650B randonneur
bike with 42 mm tires against a titanium road bike with 25s. Both were
excellent bikes, and their speed was the same. Cl
1. What does the higher mass do in regards to climbing? Help or hinder?
I wonder at what point the mass is nullified by hysteresis, s-losses, and
planing, supple tires, etc.? One could do alot of mixed variables tests to see
how it all shakes out.
2. Also, what about tire sidewall deformation u
Ah! The larger tire has more mass, so it would spin up slower. Other than
that, I'm not qualified to give an opinion.

Spin-up:
Starting from a stop and getting the bike revved-up to cruising speed where one
abandons standing on their pedals and takes their seat.
"Spinning-up" the tires/bike from the stop to cruising speed.

I remember being told this by one of the technical people from Michelin
some 35 years ago at the east coast trade show - what is now Interbike in
Las Vegas. They knew back then that very high pressures gave you no
advantage. So this tendency for tire manufacturers in the past 30 years to
rate their
In science, it's important that results are replicable - this means that
anybody doing the same experiment must get the same results. I was excited
to learn that recently, Joshua Poertner (formerly of Zipp, now of Silca)
has replicated our results on tire pressure: Higher tire pressures don't
