miata tyre calculator
the Miata tyre calculator is a really good tool to use

remember
155 is the tyre width in mm
80 is the percentage of the width. this is the sidewall height
R12 is the rim size in inches.

a 155/80/R12 has a tyre diameter of 548mm (about)
a 165/75/R12 has a tyre diameter of 547.5mm (about)

The rolling dimeter is identical for intents and purposes so either tyre is fine
the 165/75/12 is slightly wider but not enough to make ahuge difference.
All things bieng equal, a taller tyre will get more traction in a straight line then a shorter one. (longer footprint) Think drag tyres as an extreme example)
