The cinder is 57mm wide (verified) and its considered the first panaracer that has a correctly stated size. I agree that the pre-2004 lineup was about an inch smaller than stated, at least thats what the panaracer rep that i met today told me. They are 750g each, true 2.25 and they promise to be a good hardcore trail tire (ok we can put other labels....light DH/FR etc etc).
