i believe r888's are lethal in anything outside of really warm days - have heard of one scob written off because the driver took them out on a greasy day,not even wet, and went straight on at a corner....
il never put yokohamas on anything ever again, worst tyre outside of falkens ive had, so id go for the reo70's out of those
personally i swear by goodyear eagles with heavy duty rated sidewalls, on my 3rd set on this scoob with no probs standing for 4/5 months at a time - but i do like to keep charging in the rain and also a tyre that breaks away nice and progressively, nothing like edging the tail round that little bit
