This wheel was removed from the rear of a 22" Craftsman Model 917.373680 walk behind lawnmower.  The wheel is a genuine Craftsman part that was a replacement for the original wheel.  It does have some wear but is in excellent condition.

The wheel (white part) is in very good condition with nothing broken or any cracks.  The tire (black part) still has most of the tread on it.

The wheel is 8" in diameter, 1.75" wide, and the axle hole is 1/2" and is plastic.
