Need help locating front wheel/tire for old SX95 rear engine rider

[warrenpeas]

This is the old rear engine rider with the 11x4.00-5 front wheels and tires. I cant find any replacement with the correct hub length and width. Everything I find is for zero turn and is 5 inches hub length and my measurement has the one I need at 2.5 inches. Anyone else have any luck finding a replacement? Thanks.
