Just purchased a 2004 F-250 CC diesel 4X4 with 16" rims with about 60% Dunlop 10 ply rubber. Truck seems to be geared very low. Has anyone up-sized to 18" rims? I have a chance to purchase some 18" Ford factory aluminum rims, center covers and lugs mounted with Michelin 10ply tires that have only 5000 miles on them for only $800. Will they fit without interference?
