Wheel Width

[jonathan180iq]

I'm going through all possible tires that will fit on this bike and I'd like to know if anyone ever, for one reason or another, measured the width of the wheel while the tires were off.

There seems to be a much larger choice area for non OEM tires sizes and I, for one, want to know what fits.

I haven't had to change my tires so I don't have any interior measurements and I'm not about to go to all that trouble just for that.
I'll get the exterior ones later this afternoon.

Thanks,
Jonathan
