2014 F34 GT Sport Tyre Size

Recently purchased a GT 320i Sport, just noticed the front and back tyres are in different size

Front 225/45 R19
Rear 255/40 R19

Wondering if this is meant to be correct? Also steering wheel is kinda heavy compare to my X3 and 3 series loan car, a time for a alignment maybe?

Many thanks

Yes that is normal, called staggered.

it's a staggered wheel. I have changed my 18" to 19" wheels and the steering wheel felt heavier due to the size of wheels and tyres. So, that's normal to me.

From my understanding you wouldn't be able to have the same tyre size on all four corners. The overall rolling diameter of the tyre/wheel must remain within 15mm of original specification. Your speedometer will be inaccurate if you do not maintain rolling diameters. At the end of the day its your car, but i would advise not to put the same tyre size on all four.
