Question, yes I know use the search , I did. I have 17" Konigs on standby, just checking if there is supposed to be an accurate tire size so the spedometer won't fluctuate.

I have stock 16" wheels with petty hub caps.

I gots a LX Coupe 06 Galaxy Grey Metallic

Appreciate the help!.

 

205/50/17 runs about perfect if you can take that stretched look with higher sidewall
215/45/17 is stock for Si
you can run 225/45/17

the differences are so small.
