Honestly, only the spin out issue @KayTwo, but it seems no matter the rubber, it's a problem... Well, again, only a problem if you don't slow down, which I didn't due to the confidence I had from the whole trip (until the end of course).
I haven't tracked it, but rode the sisters here and the ESP light was on while doing it...
Probably won't due that again, but waiting for time to head to a dealer to repair that sensor.
As for the front, think I will go wider because the rubber doesn't push past the rim on the fronts like it does in the rear. I prefer that look versus a little gap and the rim lip exposed. So I could also avoid curb rash on the rims. Nothing yet, but ya never know...
