Traction control light comes on early with winter tires fitted
I recently fitted my 135i with new Continental Extreme Winter Contacts and noticed that when I open the throttle, the traction control light comes on. I've realized that if I turn off all my nanny modes, the car responds the way it does with my summer tires.
Has anyone else had this problem? If so, is there a way to avoid the warning without turning off my driver assists? |

I'm going to be first to state the obvious and just say let off the leadfoot
Unless something's wrong with your car (which I doubt) the TC light is coming on because you're losing traction. You're not going to have the same grip with winter tyres as you will with summer tyres for obvious reasons. That or put it on DTC. It's designed to allow some forward slip of the tyres but not lateral slip/slide.

Depends ... it does in my 1M and I believe this is because I am running a square winter setup with 245s in the rear (vs 265s). Since these tires have a smaller diameter the car thinks that they are already spinning faster than they should relative to the fronts and thus the TC intervenes way sooner (even when the tires are nowhere near their grip limit).
Also, if your winter tires are new, they may not be broken in yet. |

I'm just thinking the DSC is very sensitive and it isn't getting the grip its comfortable with with the winter tires on and intervenes early. Does the problem happen in DTC mode? |

I am sure the Alpine PA3 rubber is also not as grippy as the PS2s but the TC comes on way before I feel any slip with the winters. This is not always the case with the summers! |

I'm going to mention in case you aren't already aware...winter tires use a much softer rubber compound to grip the ice better...but that means less traction on dry roads, especially above freezing. And being made of softer rubber, I'd suggest easing up on the throttle if you want them to last more than one winter, soft rubber wears much faster...

I couldn't open the throttle in my 128i when I switched to winters without lighting up the dash and its the same case in my 1m, you'll just have to lighten up til spring.

It doesn't take much throttle application for the light to come on. So, I don't think it's my driving. The tire compound and size difference appears to be the culprit. Yes, the tires are also new.
Thanks to all those who replied! |

fit lower traction tires.
drive similarly. marvel at the traction control kicking in early with any torque you're going to outrun the grip of snows somewhat quickly. |

I had the same issue yesterday with my Toyo winters on the highway. Even gentle acceleration in sixth gear (on a good road) made the TC light come on. The temperature was warm at +11C and I'm wondering if at this temperature the tread blocks are too squirmy and confuse the TC. Interestingly, driving <60km/h on the street didn't seem to trigger the TC even though the acceleration was greater.
I'm hoping with colder temperatures the problem goes away. |
