ABS and different tyres
Discussion
If you have different age/type tyres on a car and apply the brakes sufficiently to cause the weaker tyre to lock, an old car will pull to one side and require you to let off a bit or steer to accommodate it.
Assuming you had a car fitted with ABS but no stability control system. If the front right tyre was a brand new super soft, almost track focused tyre, and the front left was a 10+ year old cheapo economy rock hard tyre. When you applied the brakes to the extent that the ABS kicked on on the left, then would you end up with biased braking and the car pull the the side of the grippy tyre, as that could apply a torque to the vehicle as it could brake harder?
Normally I'd keep them matched and change them if they were too old, but lots of people only change one tyre at a time.
