In the context of going from studded Nokian Hakapeliita 5 dedicated winter snow tires (the BEST), changing to new Michelin Premier A/S tires has been remarkable...the tires are quiet, both relative to coming from studded tires which were noisy, but even considering how quiet they are on roads scored by studded tires. In terms of ride comfort, the Forester responds well to these tires, lending great promise as a road car, likely to be better than the 2004 Forester XT we had previously and were impressed with, especially with its ability to handle Canadian roads, from Anchorage to Yellowknife NWT,Canada and back (those miles were on OEM Yokohama GeoLanders. Of course it is too early to make judgments on treadwear at just 5000 miles, but I see no sign I shouldn't have 'great expectations'.
With winter over, here in Anchorage Alaska, we have had a wet early summer and these promise to be great wet weather tires, both for traction and handling, and for resistance to hydroplaning. Re traction and handling, I've had occasion to make aggressive entrances and exits on 270 degree clover leafs, and felt comfortable with the control even up to double the recommended speed, at which point throttle steering inputs were all that were needed (air pressure bias front to rear is 35/32). Of course I'd up the air pressure in the rears if I were to take on passengers and/or loads.
Regarding hydroplaning, regular accumulating during medium to heavy rainfall is handled well by the enlarged mid-rib design, and when constrained in winter studded tire ruts common in heavily trafficked Anchorage streets, the Premiers tracked well (no opportunity to assess above 55 mph, because of traffic). In general, I wouldn't recommend general travel in heavy rainwater accumulation on paved surfaces above 55 mph anyway, but for those of us who 'explore envelopes', the Premiers have been up to the challenges presented so far.
Would I purchase another set? Yes, next month on our Dodge Grand Caravan ES.
