OP or anyone who has washed out on slick surfaces might want to have a look at the video below.
Millions of people ride on loose surfaces with all kinds of tires every day without wiping out. The proper way to corner on loose surfaces - all braking done before the turn and don't lean into the turn like a road bike on pavement.
I thought my gravel tires were garbage because the front kept washing out until I watched this video. The video is specific to MTB but applies to any bike on any loose or slick surface.
Cornering is a technique which can and should be practices and learned.
FFWD to 1:50 for the relevant part about braking.
The problem with road riding and braking is that people ride on nice pavement, see sand or gravel in a turn at the last moment, hit the brakes and the front washes out. It's classic. Tread and/or knobbies will only help so much.
