Tire Test Results : What Honest Abe Doesn't Tell You About Minimum Tread Depths: Part 2 - Dry Braking
Part 2 is dry testing, but only the car, brand new vs 4/32 & 2/32, all stopped within 1.5 feet of each other 50 mph to 0. And worn tires corner better, which kind of tells me the cooking in the oven didn't affect the rubber much.
So during the summer, newer tires on front, wear out old on rear, front's do most of the braking, wet or dry and I'm not cornering that fast, at least when wet.
