finding original looking tires for a 65 C-10

[Ed Cardinal]

I have an all original 65 C-10 and I would like to find new (older looking) tires that are not too expensive to put on the original 15" rims. Preferably ones that look less like the newer styles and more like the old ones. Maybe even square snow type tires for the back and regular ones for the front like everyone used back in the 60's and 70's.
After all, it will still be mostly used as a light-truck and not on the highway very often. ANY help would be greatly appreciated. Thanks.....Ed.
