Yard Tuff's ATV-TWK Tandem Wheel Kit is the must-have add-on to Yard Tuff's Single Axle Cart. This kit includes 2 tires and 2 tandem axle brackets. Use the kit to transform your existing, single-axle cart into a tandem wheel cart. The included tandem axle brackets easily slide onto the single axle for a fast install. The tires match those of the cart and measure 18 x 7.00-8. These tires are pneumatic tires for easy maneuverability over various terrains. The tandem axle brackets are constructed of heavy-duty steel for long-lasting durability. This Tandem Wheel Kit provides added stability when hauling loads. It also creates a greater capacity for hauling even heavier loads. Yard Tuff's ATV-TWK Tandem Wheel Kit is compatible with the ATV-3060SADC Yard Tuff Single Axle Cart.
