I think the reason nobody has given a straight answer is because there is no specific tyre that works. I raced tonight for the first time using ballistic buggys, others were running full spikes, dboots and shumacher mini spikes! There was no clear tyre to have, everything seems to work in a fashion.
It's brilliant really, an open track on a surface that nobody seeme to have an advantage.
Its dirty off road, it's what these toys were made for, its great!!!!!
