Hello all, I read up on the TCS issues etc. I have had the same aftermarket size tires on for about a year and have had intermittent TCS engaging due to the non stock size. However, the other day I started it up and after a minute or so when I get moving the antilock light comes on, if I accelerate or let off the throttle the TCS starts working for a few seconds, then the TCS light next to the Antilock comes on too. The system basically disengages and then it drives fine like the TCS is turned off. I had it in for an oil change at the dealer and they looked at it. They said that is appears that the wheel sensors seem to be in good order though. Basically said that once I get the tires sizes exact that should do the trick. But why would it do that now after I have had the same tires on for almost a year? Is treadwear enough now to make the system disengage completely on startup, maybe? or anyone else with the same problem with some input. Mine is a 92' with Nitto 255/40 17 on back and 225/40 17 on front. I haven't liked these tires and won't put them on again, I plan to use the same tires that they use on the new X's since I have the 17/17 setup now anyways. Thanks in advance for advice on this.
