Well I no longer have my Skyline but they lasted quite well considering the abuse they got (about 40 runs at the drags and 2 trackdays) and still got about 40,000km out of them. The fronts still had rubber but the rears needed replacing however they only got about half the amount of balance/rotation/alignment as they should have received.
No squeeling, tramlining was minimal but their are some pretty bad roads in my area. Yeah i'd still recommend them 'if' they are about $200ea. I haven't looked at performance tyres since buying these like 2yrs ago so i'm sure their is a new range/model of Michelins available.
