-- I assume that We are talking tread width. -- OEM on My 93, 2WD, Dakota is 215/75-15" = 8.46" wide, on a 6" wide rim. ----- I have 245/60-15" on the rear, of My, 65 Valiant = 9.65" wide, on a 7" wide rim. -- no problems, and not scary, at least, for Me. -- Shame on Me -- I'm quoting section width, not tread width. -- I just measured both tires, and Mike is very near what I found.
