Has anybody in this forum mounted Panaracer Gravelkings to the new i9 gravel wheels?
I got my wheels last week and mounting tires tomorrow. I currently use the 35 mm version of GK’s on Stans Grail rim and it measures exactly 35mm at 35psi.
The inner width of new rims is about 2mm wider than Grails, can I assume the same tire on new i9 rims will expand to 37mm? Or is that too easy of an estimation?🤷🏽‍♀️😂
I am asking because I was considering going to the 38mm tire before getting the new wheels, but if the 35’s may balloon to 37mm on i9 rims then I can stay with same tire. 🤔

I believe every extra 1mm of internal wheel width will add 0.5mm to the tyre width.

Good info. Thanks.
The i9 wheels inner width is 23.5, 3.2mm wider than the Stans, and the tires ended up very shy of 37mm at 35psi. Very close to your calculation.
