Hi all I'm a new owner of a white Z4 2.5 SDrive 2.3i with red leather I love the car only problem is the wheels are kerbed and laquer has blown on insides but the last owner just fitted 4 brand new Bridgestone run flats costing a fortune I do like idea of black wheels to fit but if I find a set to fit can I fit the run flats on other rims just wondering if I'll have the tyre warning light on dashboard ? The wheels are 18 rims bigger size tyres on rear I'm also not sure what size wheels I'll have to look for so any help appreciated lol
