So we have now also a Smart Cabrio with 61hp from the year 2003. Can only say the little one has almost more equipment like my 330er. No matter I have a question about the box. There are summer tires with aluminum wheels, believe 135 front 175 back if I don’t iree. Can I make on these rims (original Smart) without further front 175 and rear 195?? If yes which ???? I thank you already ingo
