[F36 435i M]

Hi guys,

My car is a 435i F36 on stock suspension (m sport model)

Just would like some clarification on correct tyre sizes. As I'm getting my rears changed due to them being stretched quite bad.

My aftermarket alloys are:

20 x 8.5 front ET35
20 x 9.5 rear ET45

So far I have:

Michelin PS4s 245/30/20 on the front (fit perfectly and will keep these)
Crappy budget 255/30/20 on rear (will change these)

I was advised on here to go for 275/30/20 PS4s on the rear, I have ordered them and will be getting them installed in a few weeks, there will be no rubbing with this setup? And can anyone tell me if the speedo will be impacted? I am really confused on how to work this out? If anyone can work it out it for me I would greatly appreciate it, thank you so much in advance!
