Was mowing yesterday and noticed had a flat tire on rear . When I started to remove the rim I noticed that every lug hole on rim was hollowed out . Dont know why but anyway Im looking for a replacement rim . Was told by Dealer I would have to order same rim as this is the only one that will fit this model . And it is to the tune of $200 + for a rim ? Any ideas where i might find a replacement that would work my tire size is 23x10.5-12 . Rim model i think is AVC 12757 has slots in rim design. Thanks
