Flken used to do one ( i had 175,60r12) on my mini (with mini lights) and used to drool over the 185/50r13 combo that this guy with a clubamn had. from memory they were yokohama 502 (this was about 5 years ago).
5 years ago means it does us jack all good now cause they probably not in production any more.
185/55R13 77 H CMV2
next best i could find now from uk
