Hi all, I am just thinking of purchasing the c63 AMG 19" Multispoke alloys for my C220 CDI Sport W204 car. Can anyone suggest if these wheels will fit my car and any advice of the tyre sizes I could use for the 19" inch wheels. Current tyre sizes are 225/45/17 (front) and 245/40/17 (rear) and the 19" C63 tyre sizes I found are 235/35/19 (front) and 255/30/19 (rear) so I was wondering if I need to use the same tyre sizes for my car or can I getaway with different size? I don't want any problems with my speedo going wrong. Any help would appreciate Thanks
