Pro-line R3 compound?
 

Anyone run this yet? How well does it work? Is it a really soft tire?

someone correct me if im wrong but
 

i think its an outdoor hard pack blue groove tire. guys at socal said its realy temp. sensitive so it likes to be outside.

I have used R3 compound tyres in Australia in State titles. The 2WD fronts are brilliant if you need to reduce steering twitch on a B4. The Holeshot rear R3 tyres were great on a 4WD on a very hard track that was wearing tyres out quickly. They lasted well through qualifying with excellent grip
