These decorative wheels range in diameter sizes of 18, 24, 30, 36, 38, 42, and 48 inch. The metal tire thickness is 1/16. The width of the felloe and tire are available in 1 or 2 inch sizes within the (189-xxx) pear hub. The (ASH-xxx) small cannon and (ATLEE-xxx) largest cannon are sold with only 2 inch tires. The wood used to construct the wheels are first and second material that is unable to pass road worthy status for the horse drawn buggies and wagons. Spokes and felloes are made with hickory lumber. Hubs are usually ash. The hubs have a 1 inch hole drilled through the center so that an axle can be used if needed. The wheels are very strong and are sometimes used to make garden carts, used on stage in plays, chandeliers, civil war reenactment, or just sat around for western or country display. The wheels are shipped and arrive raw and unfinished. They can be lightly sanded then slightly fire torched to expose the hardwood grain then stained and varnished. Wood can also be painted. With any wood, a preservative should be used to protect your investment for many years. A pear hub has two metal rings on each end of the hub. It measures 6 inches in length and has 12 spokes.
