Unfortunately tracks don't work like wheels. No matter what you do, some part of the track has to slip sideways during turning. This fights with grip/friction and makes turning feel poor. It's not a bug, that's how tank tracks actually work. In the real world, tanks are notorious for damaging roads they drive on - this is why. When turning, they forcefully slide the front and back tips of their tracks left or right across the road, scraping it and chewing up asphalt or concrete.
There is still some work to be done in TT on optimizing tracks. They have suspension problems and I'd argue the grip of most the recently released tracks aren't anywhere good enough (but that would make turning feel even worse). It's a delicate balance.
