Ok I was running Michelin pilot alpin a3 225x40x18 but potholes caused one of them to get a flat = replacing all tires bc they are at 60 percent tread. This was on a 18x8 square winter setup. But now I'm thinking of two options, I wasn't sure if they would fit so I need some help. I'm looking to get just a little more meat in hope to avoid flats slightly and protect the rims a bit more.

will both or either of these fit without spacers or changing anything?
225x45 on current 18x8 square set up
Or
225x45 on front 8s and 245x40 on rear 8.5s for a stock 189 rims. (I prefer this setup)

Again this is for my 2011 335 XDrive coupe, thanks in advance and I appreciate everyone's help.
