26x30/32 tires?
I just picked up a used Novara Safaria Viaggo touring/commuting bike. Really seems like a nice bike. (This is the older version, before they started using disc brakes, for example.)
However, the tires are a bit odd -- they're WTB Terrainasaurus 26x30/32 tires. They're somewhat worn, so I'm thinking of replacing them. Obviously 30/32 means milimeters, so that works out to about 1.2 inches, but I'm wondering if this is some oddball size or what.
Sheldon Brown told us about tire sizing, but I don't see anything about this mixed inches/mm thing -- should I replace these tires with 26x1 1/4" tires, or 26x1.25" tires? Or something else?
Hopefully it's just 26x1.25" tires -- that's easier to find. I haven't really seen many 26x1 1/4 " tires at the local stores.

I'm 99% sure those tires are the same as 26 x 1.25".

Check the ERTO number next to the 26" x 30/32 in parenthesis then repost.

Though I'm a dumbass, Jeff Wills pointed out that the very link I gave had half of my answer -- I just missed it.
Though looking at WTB's site, they give decimal sizes on their Terrainisaurus (awful name, but better than Slickasaurus I guess) tire now, so these are probably decimal sized.
These tires seem pretty old -- the gumwall is showing age. They've still got life in them, but I'd rather have some sort of puncture-resistant slicks instead. I'll just make sure whatever I buy can be returned if they don't fit right.
Thanks guys!

There's nothing like that -- but next to it it says C-1216N-2. Which probably doesn't designate a size at all.

Yeah, well... it looks like to me that it's a Cheng Shin model number. Not really surprising, since Cheng Shin makes lots and lots of "branded" tires.
Judging by this page: https://velospace.org/node/5017 , I'd say that the rims are conventional 559mm BSD "mountain bike" size.
