Thanks for the reply. The size difference is an interesting thought I hadn't
really considered. Given the magnitude of the *apparent* difference in
performance/mileage, it seems hard to believe that the new tires are that
much larger, but I certainly haven't tried a calibration run. I guess I was
rejecting increased heating at speed given the huge improvement in
temperature/tread life UTQGs. Of course, I've long sensed those numbers were
cooked anyway.
