Costco, as one example, WILL NOT mount a pair of new tires on the front of a car. Why, customer safety, and product liability.
If a car understeers (plows) off the road, it is the drivers fault, he/she was going too fast for conditions. If a car oversteers and spins off the road, it is the cars fault, period. This is how lawyers see it, NO EXCEPTIONS.
Thus, every modern car is set up to understeer... and tire dealers are cautious as well.
In my experience, new on the front and 1/2 or better tread on the rear has never been a problem. In extreme conditions, like a high speed curve in a down pour, yes, oversteer MIGHT happen.
When the rear tires are VERY worn, and you put new tires up front, the likelihood of a spin in wet or snowy conditions increases substantially.
That being said, every person I know with a FWD car puts new tires on the front...
Be reasonable about it, and most will never have a problem.
But know that if you do have a problem, it might involve a spin...
