It really confuses me how tires often give a width in inches and a width in millimeters, and they aren't quite the same. I have a tire marked 26 x 2.0, for example, that is also marked 48 - 559. So what's the width, 2" (50 mm), or 1.9" (48 mm)? Or something else, in that general area?
I just mounted some 2.30's on Araya 26x1.5 rims. I think the inner width was around 19mm (someone may know for sure. I'm pretty sure these checked about 2.150" with 45 psi. I'll verify this evening.

Measured last night and they actually checked right on 2.200"
