The organisers of the 2014 R.A.C Rally Championship have confirmed that tyre choice will remain open with DMACK, Dunlop, Kumho and Pirelli all partnering with the championship to supply tyres.The decision to continue a policy of allowing choice of historic specification tyres is considered to be in the best interest of competitors, who can make their decisions based on their own views and preferences. Allowing a free market policy to operate also allows competitors to negotiate the best possible terms.“I’d like to thank our tyre partners, DMACK, Dunlop (Mr Tyre), Kumho and Pirelli, for their on-going support of the championship,” said championship manager Colin Heppenstall. “Last year we pioneered an open choice of tyres for historic rally cars and we believe that this is in the best interest of our competitors and reflects the situation in period.”While DMACK, Dunlop, Kumho and Pirelli are official championship partners, other makes of tyre that comply with historic regulations are also permitted in the championship.
