The 205/75–15 sized tire is way too tall for your vehicle if the OEM size is 195/60–15 sized tire.
How much bigger is a 205 tire than a 195?
What’s the impact on mileage and body of the car? By changing your tyre size from 195/55 R16 to 205/55 R16, overall diameter of the wheel(rim +tyre) is being increased to 0.433 inch(1.77%).
Can I use 205 55R16 instead of 195 55R16?
Maybe, but only if the 195/55R16 sized tire has a speed and load index rating which is equal to, or great than, the 205/55R16 sized tire.
What is the difference between 195 65r15 and 205 65r15?
The first number (your two are 195 and 205) is the measurement of the WIDTH of the tyre. So if you do what you say you want to do the only thing that will change is the width of the tyre.
