Because it's retarded, like everything I do with my car, never argued otherwise.
Avon are not a stiff wall tyre, and today was sunny and dry here, great conditions.
With the F1 front and Avon rear you were never quite sure where you stood with it. I was actually warming up a bit to the F1 though, after a while I guess you get used to the poor turn in and cease to really notice it.
No doubt about it though, fit some proper stiff tyres and the difference is night and day. The RE070 is drastically stiffer walled than the AD08, you can't really bend the wall by hand at all, and the tyre machine needed assistance to get them over the rims

I expected to be bouncing off the roof but the ride isn't really any worse than with AD08 (which FWIW, is a lot harsher than your every day stuff, comparable to runflats?)
