Goodyear Eagle F1 Asymmetric 2 really soft/thin sidewalls?
Discussion
AS2 are certainly very light compared to tyres with proper sidewalls in them. I put these on my old 328 which had a lot of work put into the chassis and normally ran on AD08, I felt that it ruined the car. What was pin sharp and accurate steering became loose and vague, the car wallowed around and had a really confidence sapping shimmy/squirm when driven hard over rough ground. They have very good grip, but without the crisp feel I never felt confident to press on with them, I took them off after a week and went to Bridgestone.

Sadly sidewalls are getting softer and softer for better RR and noise label data.
Is softer better for reducing rolling resistance? I would have thought stiffer sidewalls would be. xRIEx said:

Soft sidewalls seems to have been a feature of the Eagle F1 range of tyres for years and years, the old GSD3 were well known for it. I find them to be unusually progressive and friendly when you loose grip, it's possible the soft sidewall contributes to this?
I made the mistake of putting them on my 2002 CTR a few years ago. They were stunningly bad on that car, particularly tramlining over the crown of the road when overtaking. Nice compound but awful construction for that car.Ok so a higher load index/speed rating doesn't mean a stiffer tyre it just means the tyres maintain a safe pressure/heat at that pressure/speed?
I guess a stiffer than average tyre acts like a lower profile tyre than it is and a softer than average tyre acts like a higher profile tyre than it is?

I'm not sure I agree with the "sadly" bit. With wheels getting ever heavier and sidewalls ever lower, I think they need to be getting softer for mainstream cars. Clark3y said:

That's pretty much how I feel about them, although not as strongly as you. But the difference with the AD08's much be huge! I think it's very dependant on the car. My early S2000 has very quick steering with not a lot of feel, this extra bit of vagueness around the center doesn't help with confidence. What I hate most is the slightly wallowy feeling on rough surfaces, almost feels like bad dampers on the car. However I now learned to ignore those signals and they are quite good when driven hard. Very grippy and progressive on the limit. Next time I'll try some AD08R's I think This review seems to support my feelings about these tyres, they also complain about lack of confidence and vague steering feel: http://www.caranddriver.com/comparisons/goodyear-e...

I would buy them for any "normal" car I get, but for mine I will not be going for them next time...

In terms of ride quality and handling yes, except the "small wheel/stiff tyre" combination tends to be lighter than the "big wheel/soft tyre" one. Thus using soft sidewalls to compensate for big wheels is completely the wrong thing to do if you value dynamics and/or ride quality over fashion. It is, however, usually cheaper than replacing the wheels with smaller ones. Yes, I can imagine they wouldn't be particularly good on track but in my experience none of the best road tyres are, you want completely different behaviour from a track tyre.
The best compromise between road and track seems to be something like the AD08 but they do have their limitations in both environments.

I run them at the moment but I'm looking for something with a stiffer sidewall. Any recommendations available in 17 inch?
Bridgestone. I wrote something about this actually:http://www.tyrereviews.co.uk/Article/Bridgestone-P...
I haven't tried the F1A2, but switched from F1 GSD3 to Bridgestone RE001/002 and they have a much stiffer/stronger sidewall without seeming to give much/anything away in other areas. Seems to fit with other comments about Bridgestones being stiffer.
I found both the GSD3 and similar Toyo T1R to be too soft for my taste (in 215/45R17), felt less precise and were much more susceptible to sidewall cuts and punctures on the loose stuff.
