Official YARIS Wheel & Tire Guide

I can't say with certainty, but your speedo will likely still over read even with 205/50 16. Every Toyota I've owned has over read. My Yaris running 195/50 16 reads 60kph when in fact my 20hz gps module hooked up to my phone reads 53-54. And it's nearly 10kph out when I hit 110 :).

I'm more than happy with the speedo reading a little on the safe side. At an indicated 110, my Forester is doing an actual 102 ish. I know that setting the cruise between 105/110 is safe as houses.
