NO, the last digits (R15 and R16) refer to the wheel (rim) size.
If you change wheels you can install the 16" tires. A much better swap would be to install 205/65-16. The parameters except width will be almost identical to the 205/70-15 tire/wheel combination. Your speedometer will read 59.5 at a true 60 mph.
It depends on if you have the clearance and the tires don't rub the inside of the fender when turning.>Al

That's a much smaller tire, you may want to think very carefully about that. I certainly would not.
