I'm also all up for controlled tyres as our club have had a lot of different controlled tyre events and the cost savings are huge. However when we at aarcmcc put it up as a trial in Truggy at the NSW states everyone was up in arms and got it stopped.
Shame really as we did try and cater for all sponsorship arrangements people have by trying to have a controlled tread pattern. I.e Impact for AKA and blockade for proline etc
All I can say is if people want it, lets start a new thread and lets see if we can get the wheels in motion again for it.
