Has anyone had trouble finding replacement tires for the 03 dually? Goodyear is the only one that makes the 235/80R/17 for the duallys that I know of. There are only 60 in Goodyear warehouses across the US and others scattered in local tire shops, none in my area. Goodyear does not have this tire in production at the present time. A wider tire will not work because of the space between the duals. Has anyone heard of another 10 ply tire that will work on the duallys.
