Hey everyone,

So, I'm having a problem where my traction control engages (or flashes) during corners at about 100-120 km/h on my F32 my 2017.

Now, this did not happen untill very much recently, when I swapped my tires.

Up untill August, I had in the front a pair of Michellin Pilot Sport 4 225/35 (18 inch), and on the rear the stock tires, which were Bridgestone Potenza 255/40 (RE50 if I'm not mistaken.

The car always had loads of grip in high speed corners, and never had a problem when doing them, since the DTC would not intervene.

Now, I swapped the rear tires for a pair of Michellin Pilot 5, and everytime I make a corner on the freeway, whether accelerating or not, the DTC always flashes in the range of 100-120 km/h. Since the car twiches a little bit when the DTC engages, I've lost confidence on the car and I do not dare making the corner in higher speeds.

When I reached Bmw, they said that this could be due to the fact that an alignment to all four wheels had not been executed. But they did just that and the problem persists.

Checked the tire pressure, all is nominal and according to the recommended values.

The tire measurement is exactly the same has my previous tire.

I've already done about 1000 km with these tires, so it can't still be the fact that they are new.

The car is going again to the dealer to perform some tests to the DTC to see if they come up with any errors, but I'm confident that they will not find any since this problem only came up when I switched the tires and the DTC has been consistent when it engages.

I'm going to ask them to do a test where they swap my tires with another pair and see if the problem is the tires, which I'm betting it is.

Any thoughts on this ? How come is the DTC engaging when it didn't with the previous tires, and in spite it is another brand, the measure is the same ?
