I have 205/50-15's and at 100 MPH my speedo is only 4 MPH fast so I think it wouldn't throw it off that much at all.

jdogg, that Miata calculator is a great tool. I think it would be appreciated if you posted the link as a new thread. I have book marked it for future use. I calculate the % difference in revs/mile between stock size and new size and figure that speedo will be fast/slow by that percentage. Is that correct?

I believe 80 is very close.
