Supersports vs AD08

Hi. i have a dilema. my size of tyres is 215/40 R18 (interlagos wheels-standard on RB7 edition). Bridgestones are not what i want so want something new. Only good tyre in my oficial size is Michelin Pilo Super Sport. BUT: what if i would buy an unoficial size that means 225/40 R18 Yokohamas AD08 ? what would you do in my case ? be oficial with michelin or unoficial with yokos which are the best tyres ?
