Unrelated to the OP, wasn't sure if warranting new thread.
Couple weeks ago I had a rear tire shred on me on the highway. Luckily the tire stayed on the wheel and I was able to limp it another mile to where I was able to change it safely. Well my AdvanceTrac and ABS light came on when it happened, obviously I think the two were related. I get a spare on and the error messages go away until now (just days) after getting a new tire put back on that wheel. The messages usually comes up immediately when starting the car, but there has been several drive cycles where the light doesn't come on until a random time while driving (seems to be when hitting the brakes like when decelerating on an off-ramp - not sure if matters).
Again, this is both AdvanceTrac and ABS indicators at the same time. I feel like if it was damage to the WSS or the teeth @ that wheel - I would have the issue constantly. The fact that it is intermittent is what scares me.
EDIT: Not sure if it matters in terms of calibration, but I have aftermarket wheels and not sure if that would matter since I was running a spare for a couple days that obviously wasn't the same size as the other 3 wheels.
