Thanks for the information Malcolm.
Plenty of Conti Premium Contact2's about but these are passenger car tyres. Your supplier is probably referring to these.
Best option I can come up with are Yokohama c2's, which are a softer compound than most of the other 6o series tyres. Alternatively to drop down to 55 series Toyo Proxes T1-R's.
Again thanks to everyone for their help.
