It's weird red, they warm up slowly on the rolling road but they are grippy from the off on the winter days, great in the snow and certainly better than the goodyears through the winter in my experience. I'm a convert, gone from ps2's to F1's to vreds and vreds are certainly my new favourite
....Vreds were my favourite when I raced bicycles but 18mm with 150psi is a different ball game!
I've been thinking of changing to Vreds but am very unsure about having the GY asymms on one axle and Vred asymms on the other. Tyre wall stiffness etc could action the ESP when not wanted. I'm doing a proper trackday with Hurdy at the Nurdleburgering in April (Nordschleife plus GP circuit) and don't want to be taking strange risks.
I had some random weird snatching moments when I had GY asymms and GY directionals mixed.
