Anyone running 255/85/16's.
Also do you know if it's possible to recalibrate the speed-o for the size difference?

I'm running 255/80/17s, the same diameter as tires you're talking about.
From what I know (and others wrote about it) Hypertech might be the only option to recalibrate the speedo.
Now, in not planning on doing it though. I know my speed is 6 mph higher at 65mph than what the the gauge says, so I adapted to it.
