The chosen tyre @ Storm Valley will be Proline Holeshot M4, reason being its what most that have completed in the Winter Series will have already
As for wear rate 1 Set will easily do the Rd there as 99% of drivers are doing 2 Rd's of the winter series use the same set
Also we don't allow pins or spikes on the track only a DIRT Tyre, the surface will cut up like a motocross bike on soil
Hope that helps and answers any questions
