affected na actual FC mo nyan dahil mas makapal na at mas malapad, also mas mabigat na yan. IMO parehas mo na lang sa stock aspect ratio, kung 70 then add ka na lang ng konti sa lapad for better traction.
If you change to 195/70/14 passenger tire, the wheel diameter is much smaller. And also take into consideration the load rating. Am not sure if there is a 6-ply rating this size.
205/70/14 is about the same size (1% difference) but you may have some offset problems. Try nyo nalang i-mount.
Changing to 195R14 will definitely result in a bigger tire.. and a heavier one. Though comfort might improve, fuel consumption will suffer.
