Now that my 440b is running I noticed one of the wheels has been welded ( badly) so I need to replace it, the tires are 23/8.50X12,which ( by the manual) are the bigger tires for this size loader but the side walls are even with the wheel bead. So far in my search all I seem to find are rims for 16.50X12. Can someone point the new guy in the right direction to look?
