What tyres for the outdoor track?
 

I'm planning running a B41? Is it strict rules if I havent got the correct ones?

Thanks,
Jay.

No rules, Yellow cut/normal stagger ribs front, and Yellow Minispike rears, outside spikes cut off thats if its dry

No specific tyre, but virtually everyone runs Schumacher Yellow Minispikes. For the front it seems to be your choice from Schumacher Yellow Stagger ribs, Cut staggers or slim minispikes - all three are used.
Actually the track hooks up well with lots of types of tyres.

Thanks fellas. I can use the mini spikes off my Cat... Ruined its esc yesterday so it's back on a shelf.
