looked up the tyres and they are listed in the 1/10 on road tyre section.
Next minute i can see tyre warmers turning up on pit tables lol.
Also what will the 4wd cars use as i can only see rear wheel tyres ??
I personal think if racers want to use these then thats there personal choice but to make it a control tyre for club i think is a bit restrictive.
It might even put people of dropping by if they know they need to get special tyres to run at mansfield.
