tire size fuel efficency 165/60/r14 , 165/80/r14, 155/80r14

Good afternoon,

which of these tire sizes provide more fuel efficiency on a 1990 toyota corolla 1.8 diesel sedan.

165/60/r14 and 165/80r14 are wider than 155/80r14 which is not good for fuel efficiency.

the 165/80r14 has a larger circuference and diameter, which is better perhpas for highway driving?

the 165/60/r14 have smaller circunference and diamter, which is better for city driving?
