Anyone know anything about them? Looks like a new tire that will be spec tire for Miata and 944 series which means they come in 914 sizes. (IMG:style_emoticons/default/piratenanner.gif)

They are a track tire, but wonder how they will do for autocrossing. Similar to the Kuhmo V710 but not as good as Hoosier A6?

I would highly doubt they are even up to the V710s performance.....just based off the fact they are designed for different environments.

Autocross tires can run a much more aggressive rubber compound, as the heat cycle durations are much shorter. Road Race tires have to be able to run for dozens of laps at pace (not counting super sticky qually tires), as such, the rubber compounds can't be as aggressive, to prevent overheating that leads to blistering/delaminating and ultimately tire failure.

If you are looking for a dual role tire (or an autox tire with a longer life, at the expense of grip)...could be worth looking into. But if you are strictly looking for an autocross tire...I would stick w/ the autocross specific tires (V710/A6 and such).
