Hey. yes i've measured it on the rim while inflated. Yes tire sizes vary, except i've always had 700x28s from different manufactureres, and i yes there may have been a 1mm difference, but this is quite obvious that it's not a 28mm, not even a 25mm. If the wrong decals are put on the tyre, and the tyre is indeed 23mm, then why is it black ? Maxxis doesn't have a 23mm in black. I'll go check it out tomorrow at their store, but these 2 tyres really made me confused - i never had Maxxis before and it's also the first time i go to that store. I'm thinking more in the lines off - if it's fake, how should i approach the situation.
