Tire spec for performance suspension

hi everyone,

i have 10k miles on my run-craps and they already need to be replaced. i'm set on the michelin pilot super sports. my question is what size/spec should i get? i have a 2012 135i with M-package and the performance suspension (prefer no rubbing of course).

original equipment:

Front: 215/40R18
Run Flat
Sidewall Style: Blackwall
Serv. Desc: 85Y

Rear: 245/35R18
Run Flat
Sidewall Style: Blackwall

are these the ones to get? should i go up in size and what about the sidewall or load range ratings?

Front: 215/40ZR18
Sidewall Style: Blackwall
Serv. Desc: (89Y)
Load Range: XL

Rear: 245/35ZR18
Sidewall Style: Blackwall
Serv. Desc: (92Y)
Load Range: XL

Thanks in advance for your suggestions!

Michael
