Is your speedo recalibrated yet for the new tire size?

Definitely following to see how these new tires do.
I thought about recalibrating the speedo, but it's not actually off from GPS by a single mph at highway speeds so I probably won't bother. And yes, they're a hair taller, but they also visibly don't deform as much. It takes less air pressure to get the same contact patch with larger tires, if my understanding is correct, so 50psi in these should be equivalent to much higher in RE92s.

Now, fuel economy is yet to be seen...

I expected these would be stickier; RE92s have a reputation for trading everything for rolling resistance, but seemingly that may not be the case.

Going to put a few hundred miles on these tires today.
