Hi,

Of the choices that you suggest, the 205/70-15 is closest to the stock 
tire rolling diameter. The 205/75-15 is a tad taller than stock, so your 
speedo will read about 2% slower than you're going. The 205/70 is about 1% 
shorter than stock, so your speedo always reads 1% faster than you're 
going.

Note that 1 or 2% is well within the margin of error for most 
speedometers, so the answer is that either tire size would be fine. I have 
a hunch that there are more choices out there for the 205/70-15 size.

regards,
rml
