Nankang CX-668

While these tyres may handle all weather conditions, they do lack in the speed and cornering department. It makes me think of driving with cross ply tyres. The only reason I chose these Nankang tyres is because they were the only brand with my vintage car size, but I'd love for other brands to make them again.
