Hi forummers I've been following this forum quite a while now but this is my first thread .. I'm currently driving e60 and using the m sport (135) rims (18"). I'm thinking very hard of changing the rims to Breyton GTS 19" rims. The problem here is that a few of my friends actually change from using 19" back to 18" rims due the reason that they said that the ride is quite hard and bumpy due to the profile of the tyres. So I would appreciate if you guys could leave me some feedback whether I should go ahead to change the rims and tyres or I sould stick to my current rims ... thanks in advance!!
