18' or 19' wheels on E60 2006 525i

[madman6678]

I'm looking for some opinions on what I should go with. I have a 2006 BMW 525i with original 225/50R17 all around on my car now. Looking to upgrade the wheels to either

18' staggered 8.5front 9.5 rear Beyern Wheels - Beyern Mesh Black with Polished Lip with 245/40R18 Hankook Ventus V12 Evo K110 front, 275/35R18 rear

Or

19' staggered Beyern Wheels - Beyern Mesh Black with Polished Lip
245/35R19 Front Hankook Ventus V12 Evo K110 275/30R19 rear

Advice, ideas, criticism’s greatly appreciated in making this decision.

Some people say 19' crack easy and the 525i weight can't take them and there a rough ride.

Some say the 18' are a better ride and don't crack and are in-between style and performance. Let the opinions begin.
