as long as its progressive there's nowt wrong with letting go.
i have falkens in 285/30/20 and 255/35/20 and i struggle to get them to let go on anything other than gravel and thats with TCS turned off and nearly 400BHP of SC'd V8 behind it. in the wet, on roundabouts, country roads, standing water etc its well planted. now the pirelli Pzero assimetricos on the other hand felt horrific in rain. you could feel the backend wonder at speed. not a pleasant experience.
so i think that the issue with the tye for the zed is most likely to do with the fact that the zed needs bigger wheels as standard with a lower profile and a wider footprint, for those that feel they need more grip.
speak to husky he had 19's with 295/30/19 on the back and god knows what on the front and he said he had more grip than he needed and that was with sessantas. just couldn't break traction.
the thing is thats all well and good if you want grip that sticks like sh1t to a bears arse. but the zed drives better with a progressive setup. you want the car to be able to kick out on occasion, a bit of gentle oversteer at the rear. yes the car is setup for more understeer, but thats what nissan setup to make it safer for numpties.
if the zed was meant to be imovable nissan would have put bigger wheels on. they didn't they put 18" 245/45/18's and 225/45/18's on so the car had character, some play, a bit of excitement. but not enough to kill you the first time you sit in it.
