Correction, use 215/70r15 and your speedometer will be almost exact. Below
is the stock 215/65r16 VS the 215/70r15.

Specification Sidewall Radius Diameter Circumference Revs/km
difference
215/65-16 140mm 343mm 686mm 2155mm 464 0.0%
215/70-15 150mm 341mm 682mm 2143mm 467 -0.6%

I just bought winter radials and buying the 15 in. tire VS the 16 in. tire I
saved over $20 per tire.
