406_47 (marathon +) & I have plenty of side & fork clearance on my Pocket Llama ,, CR 18 rims.. but , Radially, I have to deflate the rear to get it in and out.
worried about being oversize ~Go with the 50 ... get 3, spares are Good things ..
Like I wrote earlier, the inner width is usually ~5 mm narrower. I'm fine with just subtracting from the outside width to get a decent estimate.
This is for a triplet. So there is a 10% difference in width and ~20% increase in volume with going from 50 to 55 mm. So the increase will be meaningful, IMO. Anyway, I'm still hoping that some folks out there have used the tire and can give me a few measurements.
