My first all-season tires, have them fitted for just over a month but apart snow and ice I have already tested them in almost any environment they would appear in (hot, dry and dusty summer, grease after short shower, torrential rain, "normal" dry and wet roads, cold mornings etc.). First impressions: quietest tires I have had in the past ten years, at least of those fitted on this particular car (Bridgestone ER300, Goodyear EfficientGrip Performance, Nokian Wetproof, Nokian WR D3, Continental TS 860), also lowest fuel consumption.
Handling and safety: I would compare them to both Goodyears and Nokians when those were new in terms of traction and breaking distances in dry or wet conditions; although I would say that both summer tires had better traction in torrential rain and standing water (I'm not going to break any speed records in those conditions so I don't mind). It might seem to be a strong statement but keep in mind that this is a recent model whereas those summer tires are quite old but stll sold as new (almost all manufacturers stopped introducing newer models for smaller cars so it is an absolutely valid comparison).
I am not going to expect how long they are going to last and actually I don't care. The winter Continentals are still pefectly OK even after nine years without any signs of deterioration but the Goodyears became dangerous after their third season (cca 20.000 km) and had to go with 6 mm of tread left. Nokians were better, after five years of use and cca 25.000 km they only started showing first signs of losing their original grip at the moment they were replaced (punctured sidewall by a sharp object on two of them). So if I replace them after five years and some 35.000 km because they have worn out without losing grip, I would be absolutely satisfied.
