I purchased a WTB Weirwolf and a Prowler in the 2.3 width to put on Sun DS1-XC rims but the mounted tires measure out under 2". I want to to have tires that will measure out +/- 2.3" but don't know if the rim which is supposed to measure 23.5 is too narrow and causing the problem. I haven't been able to get any help from WTB:confused:

What do you really want and how are you measuring? The nominal (inch) size is fairly useless. There is no standard. Is it the tread or the casing? What rim width? At what pressure? How long has the tire been inflated?

That is why WTB does this: http://wtb.com/usa/tech-gms

And I do this: http://mtbtires.com/specs http://www.mtbtires.com/tech/measure.html

Your rims are narrow and the tires are new. If you were measuring the casing it could be under 51mm/2" (Spec for the Prowler SS/XT/MX 2.3 casing is 54mm/2.13". WW 2.3 52mm/2.05" for the casing). If you were not using calipers the measurement was far from accurate.
Inflate the tires to 60psi and wait a day and they can be ~3mm wider/taller than when first mounted. Will usually measure wider on a wider rim, too.

Shiggy's got you covered on this one. I have the prowler and on a Sun SOS (28mm rim IIRC) it measures 2.3 across the knobbies. My first thought was that the narrow rim is keeping it in a bit and not allowing full width. The prowler is the absolute max width tire recommended on that rim as well, so you are unlikely to do better on width.

Spec Eskar 2.3 actually measures 2.3 when I had it on my bike.

700 gr + sealant for tubeless, not bad.
