[NHAero]

I found a pair of used DT Swiss wheels with R460 rims (rim brake) with an inner width of 18mm for my Bob Jackson. The Conti GP5000 700Cx32 tires at 55 psi measure 32mm. On the old Mavic Open Pros they were very slightly over 30mm. I think somewhere I read that every 1mm of inner width will generate 0.6mm of tire width increase, so this seems about right in this case. On my Supersix, I went from Mavics at 14.5mm to Farsports at 21mm, and the Agilest 25mm tires gained about 3mm in width IIRC.
