.. there are compromises. My original post talks about most of them. The car does follow road irregularities. The bigger the change in the road surface and as it appears, the slower the speed, the more it wants to change direction. I have heard that they are very pressure difference sensitive. Left to Right that is. The only time they caught me by surprise is when I was slowing for a red light and there was a sudden six inch plus change in the pavement left to right. I don't think they ride as well either, but it doesn't seem to be a lot worse.

As for speed rating, I don't know. They are road race tires! A lot of people in here, myself included, get pretty excited about speed rating. For me it was based on a probably not scientific assumption that the higher the speed rating the better the perfomance. Just seems to be the way they make them. But it seems to be factually little more than the highest recommended speed you can sustain before you run a significant risk of having the structure come apart on you.

If any one has more information on speed rating, I would be interested in hearing some professional facts about this.

Still like them very much. One side benefit that may be here for many of us is that they DO NOT like a bunch of Camber. Many of our suspensions where not set up with much and do not have high rates of camber gain. I look at that quality of the tire as a bonus.

If you are going to push the car to the limits on occasion and don't mind some of the negatives, you will like them. Strickly cruising, I would stick to some of the others mass produced radials out there.
