285/30/20 instead of 285/25/20? In trouble?

Hi, ive just bought a set of 20's for my 2008 E92 sport. The wheels are by a UK company called Kahn and have specifically been made for the E92. Im in a bit of a dillema, ive been told that I need 295/25/20 in the rear BUT can get my hands on a set of Michelin PS2's in 285/30/20. Is this going to be a problem if I put them on my car?

Thanks!

That is too large of a profile tire for the 20". You can squeeze a 275/30/20 depending on the bulkiness of the tire and wheel offset but would need to roll your fenders. Otherwise, we recommend a 285/25/20.

The overall diameter of a 285/30/20 is too tall. I wouldn't recommend it.

I would not do it because the 20" rims and tire is already taller than stock and will be throwing off your speedometer. If you go with a 30 profile the tire is even taller and will make your speedometer off even more than it already is going to be when you get 20" wheels.

I also feel that 285/30/20 is too large for the e9x, 285/25/20 would be my choice.
