Cut-up tires can provide adequate bunker silo coverage and save you time and energy. Sidewalls, tread and the whole tires are used interchangeably to weigh down the plastic sheeting. New York dairy producer David Wood finds the sidewalls and tread much easier to handle than whole tires. He estimates that it takes one-half to two-thirds of the time to cover the silo with cut tires than it would with whole tires exclusively. Plus, the sidewalls and tread don't collect water. As far as silage quality is concerned, Mr. Wood hasn't noticed any difference using cut tires compared to whole tires. He pays 50 cents per tire to have the tread separated from the sidewalls.
