Yes, that is a good swap.
205/60-15 or 175/70-15
Yes they could .
You can switch to a 215/50-15 or 175/60-15 if you can find any tires in these sizes. Other optional tires which are acceptable are 205/50-15 and 185/60-15 which you can find. My advice is to stick with the OEM size.
195/50-15 is acceptable but 205/50-15 is better. 175/60-15 is acceptable but 165/60-15 is better. Any of these will work well.
No, if you are going to a 70 series tire then you will need to go with 195/70-15.
NO. Rim size incorrect, they will not fit.
185 60 r 15 could replace them.
Of course not you cannot install 15 inch tires on 14 inch wheels or vice versa. 14 inch wheels require 14 inch tires, and 15 inch wheels require 15 inch tires.
Yes, you can substitute the 205/75-15 for the 215/70-15.
205/50-15 or 165/60-15 are excellent substitutes. Just make sure you do not have clearance issues with the 50 series tire.
NO, that is not possible. Rim size is different and even if you found same bolt pattern there would be problems.
I doubt it and certainly not on the same rim. It's possible, but I would ask a tire shop pro to check it out.
