Wear on the Z8 seems to be phenomenal.
I have them on my '17 Z900R and I don't spare the throttle or rear tire. I ride that bike for one reason only, to accelerate hard and occasionally lift the front wheel.
The rear tire hardly looks broken in and I'm pretty sure there are a couple thousand miles on it. And no traction control on that bike. Still has a very rounded profile.
I just put them on my 650's and found I could lower the pressure to 26F, 28R.
Seems crazy low but for twisty roads it's perfect.
I checked the hot pressure after getting back from a ride, front was only 30, rear was 31.5. 10 percent rise, just about perfect. And far more grip and feel than stock pressures for max weight.
Truth is I have the same issue that Pedrosa has, I can't get any heat into the tire because I'm so light. Carcass is really stiff for my weight. Lower pressure did the trick. As long as the pressure rise is about 10 percent, it's fine.
Along the same lines, I dropped the front in my ZX-10R (uses Metzeler M7RR tires, softer carcass, sportier compound) and it also rose to 30 psi from 28. But with 32 in the rear, I saw a rise to 36.5 psi. That's too much flex and heat in the tire. 34 psi rear, should be about right.
Freeways, I'd go quite a bit higher but still below max.
