' I did not think I was going too fast'. A common remark from people loosing control of front wheel drive vehicles. What the average person and some experts are not aware of is that there can be as high as 950 pounds or more weight on the front axle of their vehicle than the back. So a car that feels like a limousine on the front holds like a golf cart on the back
A 3000lb car with a weight ratio of 65% front weight and 35% rear weight will weigh 1950lb on the front and 1050 on the rear. After you use 10 gallon of fuel from the rear tank one of the front wheels has as much traction as both rear combined.
If you analyze single vehicle accidents you will find most of them had better tires on the front than the back or a very large weight difference. In fact the worst balanced cars have 4 times as many fatalities as cars designed with better balance. How are you going to tell how fast is too fast under these conditions when it is possible for a balanced car to handle fine on a slippery surface at 50 mph and an unbalanced car to loose control at 20 mph and both to feel the same to the drivers.
A quick check of tire sites will show that the most important tires on a front wheel drive are the rear.
