I´ve just fittet the the TT2 on my 4/4.
I am more than happy with this tyres!
My Contis did squeak very promt when I was cornering a little bit quicker -an I really mean "a little"!
I have to say that the Contis did this from new on!
In comparison with the Contis the TT2 seem to stick on the road like racing tyres! I tried to start the TT2 to squeak on the same streets: There was no way! I stopped this tests because I was driving on public roads.
On wet roads I have no experience with the TT2 but worse than the Contis can´t be possible I think.
