Tyre Recomendation (275/45 R18)

My Dads Mercedes S-Class is in need of 2 tyres, Currently has 275/45 R18 Continental ContiProContacts.

Any recomendation for decent tyres?

I'm running falken 453s on the f10 at the moment and find them a good all rounder

I'd stick with the Contis

I have 275 35 18 Pilot Sport 3's on my car and I find them excellent.

Make sure you get xl tyres for the rear not sure if they all come in xl in that size but just keep it in mind
