Harbor Fright 8" plastic '3 spoke' wheels (100 lb rating) at 6.99/pc are a direct replacement for the Sears/craftsman/toro/etc front drive push lawnmower REAR wheels. Fits on 1/2" axles and the 1 3/4" width is the same as the stock wheels so no washers are needed. Wish I could find just the tires for the fronts, they are slicks! Just spin in wet grass.....

It might sound kinda hillbilly, but just wrap a couple of strips of expanded metal (cut to size) around the drive wheels and secure it in place with a few sheet metal screws. Works. (Protip: works on the grandkid's PowerWheels, too. :))
