While it would seem that putting them on the front in a fwd car makes sense (on cursory consideration) since those are the drive wheels, this is a bad practice. Putting the better traction in front will aid acceleration and turn-in, however the problem comes with braking and cornering. With better traction in front and the poorer traction in the rear, the car will be much more prone to oversteering, but the real danger is that under braking, you have less traction in the rear and the car will be much more likely to spin out ESPECIALLY in inclement weather.
There have been numerous tests conducted specificall with these setups that demonstrate that not only does a car exhibit better control under emergency braking with the better traction in the rear (stops in a straight line as opposed to spinning out), the car actually stops in a shorter distance if you have ABS. The reason is that with ABS, the wheels sense lockup which triggers the ABS. The rear wheels already have lower traction when braking due to weight transfer. With lower grip tires, they lockup much sooner, which causes the ABS to trigger earlier and continue activating longer, meaning the ABS allows the car to roll further because the rears are locking up much more easily. To reiterate, these are TESTED results, not opinion.
Although one would think that with the weight transferring forward during braking, having higher grip tires to take advantage of the greater potential traction in front would be better, with ABS, it's the opposite, AND you're more likely to spin out when braking hard. In cornering, you're also more likely to understeer with the lower traction tires in the front, but when you're understeering, simply slowing down helps avoid it in the first place (and letting off the gas when you experience understeering induces a weight transfer to increase front traction). In addition, by limiting the acceleration (in a fwd) and cornering traction in front (irrespective of drivetrain config), the driver is much more likely to instinctively/reactively reduce their speed to the traction conditions, whereas better traction in front may instill false confidence, coupled with the greater propensity to spin out.
