This is a pretty interesting thought experiment, but I think it’d have to be noticeably out (like, he has rim brakes - more out than would be able to go round with those) for that to happen.
It’s probably more the pressure, I’d run it at closer to 80 than 120 for sure - especially checking pressure when cold.
Another wild card is if your pump gauge is even right? I just bought a gauge after listening to the Silca guy on Fast Talk, and my pump is between 10-20 psi out at various ranges. I can imagine 120 which was actually 140 cold doing that in fairly short order!
