                Hi
                        Can I fit A4's five-spoke 7*16 on Audi S4 ? the
tires will be 225/50-16, is it
                to wide for this wheels ?
                        I have to make sure, because the price of A4
five-spoke wheel is $800 each !!

                                                                            
                    Thanks
