My 51' 1 ton has 17x5 3 piece rims. They are in good shape and I'd like to keep them. Right now my rear tires are courser traction (by cooper) and look to be in good shape with no dry rotting. My front tires look older than I am. 7.50-17 seem to only be available as specialty tires for big money. Is there a narrow tall 17" radial that will work on the old rims? The taller the better to offset the gearing. My courser tires are 34.5" tall.
