4.80/4.00-8 tires and rims. White rims are off a garden cart and fit a 11/16" axle and gray rims are off wheelbarrows that take a 5/8" axle. Gray rims have very little use and white rims have a little more use. Gray rims have bearings and are a bit nicer. $15.00 each. Dirt and dust are free. Thanks for looking and God bless.
