Any speedo issues going from 205 50/16 to 205 55/16 on the 850 turbo? Looking to smooth out ride a bit and go A/S. Car came with 16" Columbas with Mich summer tires at 205 50/16. Why does gas door say standard size was 205 50/15 when car came with 16's new?
I believe it's something like 3% difference when you go from 50 to 55's. We did this on our 850 when Volvo recalled the Columba wheels years ago, giving everyone new tires or $500 towards new ones of that larger size. Really, we noticed very little difference except we no longer had to contend with bent rims.
