Sorry TS, had this UC6 stock from the car. 19", X70. Same car? For me UC6 just junk on wet, when the car and tyre still new, it kinda skid at heavy rain like struggling at normal speed. My other car with Michelin PS4 miles better for wet traction. And most other owners telling me the same for UC6. I doubt UC7 had major improvement, except those YouTubers who die2 praise the UC7 cz they got a brand new tyre foc
