Nice detailed photos Ryan. Pretty neat to see old rubber.
As others have offered, the NDTs and NDCCs were the stock tires for these old beauties.
Original style tires look cool, and have that "feel" you can only achieve in an old Willys with an old style tire.
A modern radial tire will perform better in a variety of conditions.
A tire that has an 'Old School' look, but is said to perform better in certain conditions is the Super Traxion.
When choosing, I guess it always come down to how you use your Willys.
