Yes, you are correct about Ferrari. I was using tire rack as my guide, but I googled Ferrari and run flat and Googyear came up under Eagle F1s and they have beening working on run flats in this ultra high performance tire. Only a few tire sizes now and not Porsche 997 size. Yes, I too would be interested in great run flats for a couple reasons. I use cars everyday, year round, and do not simple let them sit in the garage. I do not live in major urban area. I have all kinds of road side service option available, but I have often found NOBODY, even the dealers have the exact tire I need (ie right front from this or that tire company in stock) when I am on the road. I am a real world driver and love the idea of run flats assuming good performance. However, my wife had runflats on here Lexus 430SC (powerful engine but not geared or set up as sports car)and the average car was getting horrible tire wear in very pricey tires. She gave up and went with non run flats, fix-a-flat, and Lexus road service ( oh yeah, there is me...who I am sure is the first person she will call to come and help her....then the run flats may seem cheap to both of us!!!
)
anybody know of a tire company making or about to make run flats in 997 tires sizes????
