Tire sizes vary somewhat from tire to tire and manufacturer to manufacturer.

It isn't uncommon for the wrong decals to be put on stuff, or to get it stuffed in the wrong package, but I'd be surprised to see a tire embossed like that with the wrong size.

How are you measuring the tire? Is it mounted on the rim?

If you bought the tire from a store, take it back, and compare to different tire sizes that the store has in stock.
