hah, coming from onroad, control tyre there means one and only one type of tyre!
Presume if dry darts, bit soft spikes, not sure what the BB's are? Any suggestions for 4wd fronts? I plan to do Nissan and Teesside but never raced on grass but I don't want to have to buy 40 tyres
You don't punch holes in the tyres do you at the end of the event like I heard they did at some last year?
