I don't think they will perform/grip as well as your current V12E2 coz both are low-mid range category only. Triplemax seems decent though for mid range tires as there seem quite many positive feedback but having said that, the V12E2 managed to outperform the top of the line Goodyear F1A3 during Car & Driver comparison test so I'd say safe to say this lower Goodyear Triplemaxx would not fare any better. Then the UC6 is only the 2nd lowest model from Continental and more focused towards comfort and durability. I got a colleague who recently bought this UC6 for his Camry coz he didn't know better and regretted it coz he said the tires feel a bit floating especially in the wet.
