Hi,
I was looking at the Miata.net tire calculator and trying find which size of tire would be a perfect match/upgrade for 16" to 18" without messing with speedo accuracy.
What I found was:
To get a 0% difference between the 245/70/16 and the 18", you would have to use a 325/45/18... Is this even physically possible on a VX (stock height)?
Thanks!
