20" Rims - Turning Radius Issue

[M3_Defector]

I have a 2007 RS4 with 20" Rims & kw3 Coil overs. Ever since I installed the rims my ABS, Traction Control and Emergency brake light has been light on my dash while driving. Took it to the dealer 2x and they advised the turning radius of the car has been changed given the 20" rims which is causing the error code or the lights on the dash. They have tired playing with the settings but the issue keeps coming back. Anyone else had/has this issue? If so have you been able to rectify it? Thanks in advance

I think you just should have put thinner tires so that the wheel size wouldn't change. What's your tire size? What is the rim width?

if you place the right tires you shoudl nto haev any issues.

Have driven 17000 Km with my RS4 V8 and 20 inch wheels but with 255/30/20 tires.

if tire size differs too much from that than that is whee is your issue.
