To quantify how wear changes tire performance, the CR tire team measured the wet stopping performance and hydroplaning resistance of 23 performance all-season tires with full tread, which typically measures between 9â„32" and 11â„32", when new, and compared it against the same model tires shaved to 4â„32".
I found some of the test results (wet braking, but not hydroplaning) posted at another forum:

I'm not surprised to see 2 Michelin tires among the top 3 for best wet performance when worn. They have been emphasizing that performance aspect:

Currently, the industry standard is to test wet-braking performance of new tires; however, wet-braking can change drastically as tires wear over time. That means consumers make purchase decisions based on a specific factor that becomes less and less relevant the more they drive on the tires.
Michelin is taking steps to close this gap. Though drivers value different aspects of safety, braking distance (especially wet braking) is recognized worldwide as one of the best indicator of safety in the automotive and tire industry.
Results show that braking performances among new tires are not equal—and a demonstration by Michelin revealed that worn tires can be even more unequal in their braking performances.
