on the current IS "F" Bridgestone Potenza RE050A. I noticed the side wall sticks out, the rubber part act as a guard against curbage. I also notice the higher end Porsche 911 has it too. Is that a style, because some RE050A does not have that. Can someone explain this.
Two very different sidewall.
255/35/19R 96Y RE050A
255/35/19ZR 96Y RE050A
Both have same heat and wear ratings.
They both look identical but without the side wall protector against curbage.
I would be interested to know what tires people are seeing most often on these vehicles. We have had two arrive here. One Nieman Marcus Edition and one Standard build. The Nieman had Bridgestones and the Standard Build had the Michelins.
