It was on a 5 series BMW.
Tire sizes may be common among people who used this size but does one set have a deeper tread than the other. That could be your problem.
Doesn't have to be exactly the same. The car's electronics can compensate to a certain degree. The front and rear rotational difference is very small in this case, .85% to be exact. Cars have run setups that have a difference of 2.5% and more, and they haven't reported any issues with the VSC.
Its definitely the different tires. Different tread means different traction; the VSC kicks in to compensate.
