After shopping brands and sizes all over, and consulting fellow 'Bolters (Longbox55), I bought new Goodyear P235/75R15 Wranglers on my 1950 1/2 ton last weekend. They ride smooth and handle great. I also wanted a tire that filled up the wheelwell better than what I had so I went with this bigger, taller tire and am really pleased. It has a more aggressive truck-like tread design than an true passenger car tire, but it looks great on the old Stovebolt.
Hope this helps.
