Continental makes their Contitrac Sport in this size, I know some 4th Gens came standard with these, I have 17s now and I am lowered and the added side wall will fill in the space nicely however with the ride suffer much. As far as side wall in mm(s) the 225/55 sidewall is 123.75 mm tall where as the 225/50 is 112.50 mm tall in another comparison the 16inch stocker 215/55 sidewall is 118.25.

I my metric memory is correct 10mm is one centimeter (correct me if I am wrong) so the tire is about a centimeter taller. Will this work.

Thanks
