Thanks all. I have a 2009 Z4 30i. These are the rims and tires I currently have. I don’t ride too aggressive. I’ve been told the Pirelli tires have a lot of loudness after awhile but are nice and grippy? Do you suggest I keep these 18 rims and just have the alloy redone? Can I get better performance than these Bridgestones? Budget not an issue as I plan to keep the car for decades and want to go with something good. I don’t drive it very much maybe 5,000 to 7,000 miles per year. I am 50/50 on 19s. Does bmw make and black 19 inch rims ? I still do like the style on these rims a lot. I guess I’m between Continental, Pirelli, Bridgestone, any other considerations?
