3:55 or 3:91?

I never thought about that. I should try to find a taller tire.

Your 235-60-14 are just a little shorter than stock its far from super short. A 28" tire on the other hand is tall. A 68 Formuls S tire was an E70-14 at around 25 1/2" tall.

I run E70-14s with 3.91s and I think its easy to live with.
