"Fetch,"
I was going to go with LT215 x 75 x 15's as well but I found them too short. The 215 is mounted on the stock white rim in three photos.
I had 235 x 70 x 16's, but decided to get away from wheel spacers I used for the late model rims.
I went back to the steel 15 x 5" rims and these Yokohama tires from Summit.

They are pricey but had the look I wanted; tall and skinny.
