I have to admit that while I’ve seen films of the wet track testing done at the Michelin Test Track on this subject, with only 50% of the tread removed (they skim it off on one of those truing machines), I too have had reservations. Especially with the advent of ABS. I’m wondering what if any effect ABS would have on the testing.
But I have to go with the available data at this point even if it feels weird.
