What are you talking about? You don't have access to the ETRTO standard, and the few members of this forum who do will never share it.
You, and everyone else, is talking about third hand information. Nobody has any idea what standards tire manufacturers are following, unless said manufacturers disclose publicly. Which they haven't.
Do you know the Tufo measuring rim width for the 40-622 and 44-622 Thundero? Do you have access to the ETRTO Design Guide for Cycle Tyres?
No, you don't. You are making things up.
Why are you here?
