Guys,
I have already changed mine to Dunlop GP211's in a 200/55 rear section, mainly as the Pirellis caught a massive steel object through the rear tyre on day 2 of ownership! So that wrote off the Pirelli and I had a set of GP211's lying around.
It makes a difference to every TC system if you change the tyres - as the slip map is designed for one tyre profile. That is why all the decent aftermarket TC systems let you alter the tyre choice in the profile of the TC unit to let it know which tyres it is running. On these OEM systems, you can't do that. They are designed to run on one tyre only.
ABS doesn't work the same way and as it is basically working at it's foremost when you are bolt upright on the brakes, changing tyres won't alter it much if at all.
But leaning right over and expecting the TC to function the same with all those different tyre profiles is not going to happen. The original 1098R systems were the same. Change the tyres and you had to have that thing down on level 1 or 0 to run it on track or the TC was kicking in all over the place.
However, for street riding, you aren't going to notice. I get the little amber light on a few times a ride when it shouldn't be doing anything but I am leaned over and on the gas. It is because it is detecting the relative tyre speeds have changed and thinks the rear is slipping. It isn't. It is just because the profile is different to the Pirellis it was meant to run. The retardation in the system is negligeable and you don't even feel it, just see the little light.
When you switch to race tyres, with a massively steeper profile, the system will be all over the place and you will have to knock it down to levels 3 or below I would guess, as the far steeper tyres will be interpretted as slipping when they are not. If you turn the sensitivity right down, it will presume you are wanting to allow lots of slip and it won't cut in. That's the only option for a one-tyre TC system.
Ducati will be very sensitive to this as they a) got Pirelli to design a tyre for the bike and b) want to showcase their new super-model in the best light. They know that the TC won't work the same with the other tyres.
If you look at just how steep those Power Cup tyres are in that picture above in profile compared to the Pirelli SC's on the bike, you will see just how different the rolling radii are going to be when the bike is cranked over compared to the stock tyre.
As this bike is not that stable to begin with, those tyres might make it a bit of a handful, but it will grip like glue at full lean with a profile that steep.
You are also correct that tyre wear will make a difference to the system. As it wears, you have to turn the TC system down and allow more slip. But as the sides of street tyres don't get that worn down typically (on track they do), the TC will continue to function well enough even if the centres are a bit worn. On track, once you start cooking your tyres, even on the stock Pirelli SC's, you are going to have to turn the system down as you go.....
