Bro sincerest advice.....
STICK TO OEM SIZE.
If cc6 not aval then Advan DBs are time tested kings. And if u still wanna go for contis then mc5 are aval and they are a notch above advan dbs. @syedahmedsaad has installed them on his turbo n he has all praise for them. ( he got from karachi n shipped to isloo )
Again DONT CHANGE OEM PROFILE.
WARRANTY MATTERS ALOT.
Its nearly 3 million of your hard earned money on the line so warranty matters.
Dont & I repeat dont get fooled by tyre dealers.
Jux my 2 cents... Rest your money your choice
Best of luck
