My 73 B currently has a set of Michellin XZX's on it, size 165SR14. The tread is good, but the sidewalls are badly dry rotted. I haven't had any luck finding an exact replacement but I've determined that a 185/70 14 is very close to the correct diameter, so I'm throwing it out to all of you as to what your experiences have been with different tyre brands and models. The car is only driven in fair weather, so an all season radial is not a high priority. Any suggestions or comments would be appreciated. Happy motoring.
