I like the calculator on this site:
https://www.wheel-size.com/calc/
Plug in your starting wheel and tire package, plug in the comparison package, and it tells you the differences.

Speedo will run 4.2% faster in the 205/55/15
compared to 205/55/16. Difference of
about 2.5 mph at 60 mph.
Those 16s are a bit taller than stock, and
those 15s are slightly shorter.
