These wheels are the same ones we use on our Goat Wagons, and our Wheelbarrows. These are made of Hickory & Ash, and have a forge- shrunk steel rim. There are 3 different colors; Red, Green, & Unfinished. They are built well enough for functional use. They come in 3 sizes, 19", 15", & 11", and they are 1.5" wide. (Hub hole sizes: Large = 11/16", Med. = 1/12", Small = 3/8") They comes in a rustic, rough-cut, and a fine finish. (Fine finished are made from the premium wood board, are is sanded smooth.)
