Let me start by saying I have had many nitto tires, started with my first in the late '80s. their dry racing tires were great as long as they were not heat cycled too many times, cheap and very sticky
refused to balance, would shake for 10 miles or so before they would warm up or "round up" and in a convertible its much more noticeable than a hard top or a heavy saloon. living in the northwest rain is inevitable... even in the summer, yes they slide easily in the wet, the last tires I had that were this bad in the rain were cooper cobras ( lost %15 on my time at autocross with them, now I know why they sponsor drifting comps), the carcasses seem hard, very little side wall flex even down at 28psi, and if your going to take your car to the track why would you waste your time with these? paid to have them changed after 3 months of hating them. tread wear? get a set with a 40k warranty and turn them in for new ones when they wear. lets face it,,,the stickiest tires usually have the fastest lap times, OR out stopping the brake jumper in front of you.
maybe these would be great for drifting competition
