They come included and God forbid if a person lives in a cold climate and expects to fit these tires in spring or winter. These tires are so compressed and deformed for lost of words that I had to have a heat gun to soften up the material just to try to install the tires and this setup was in the middle of Tennessee and bead resealing is a problem. a terrible problem because again it is a deformation of the tire itself and from my point of view I will never buy again these tires sent in this condition. If it is the Lord's will, I will go to the north tool and pay more. but I will buy the product. Shelves in proper assembly condition and an offer to the supplier to ship them in proper condition and in the box. I just can't believe someone would ship these tires in such a distorted way.
