Jim's OK Tire has a nice selection of tractor tire feed bunks for sale. We have a large assortment of bias tires that have been turned inside out to feed livestock. We have medium sized bunks like an 18.4-26 that work good for feeder calves. We also have the 34's, 38's, and 42's available for the full sized critters. Delivery can be available. The price is $30 each for the medium sized and $50 each for the large ones. We will also turn your tires for $25 each if you have your own casings. Call Trent at 308-470-1432, Jim at 308-470-0542, or Jim's OK Tire at 308-425-6517. Thanks!
