Inherited these Firestone Firehawk TZ 200 Fuel Saver Tyres virtually new on an Audi 80 Quattro. Average to good grip in the dry but poor in the wet. 195/65 HR15 spec, no tendancy to tramline at all, no vibration, no need to rebalance through the life of the tyre (just under 40,000 kms).

On the whole, I'd buy again if they did actually save fuel but won't really know that until after I replace them with something else and compare.
