If you read the BMW press releases at the time, definitely to save ... costs, weight, emissions, (that is the big one), more flexibility in using the rear well.

Sold to the customer on safety, but other reasons were driving the move to RFTs.

Also remember the tyres were supposed to be about 10% more expensive, at most. There was no discernable difference in driving characteristics, we were sold that as well.
