Yes, you can
Can you replace 205/65/R15 with 205/75/R15
Yes, you can.
the tire size is 15s Nope wrong...205 55 16 with aluminum alloy rims on the z24 model
Yes, that is a good swap.
Yes, this is an excellent substitute.
NO, the rim size is incorrect.
You can replace them with 205/60-14 or 175/70-14.
If the front tires have enough room to turn without rubbing anywhere,
Your best choices are 205 60 r15.
205/60-15 or 175/70-15
No, if you are going to a 70 series tire then you will need to go with 195/70-15.
