My tires are Primacy+ SUV which I believe is equivalent to Primacy 4+ in Australia for this size of tire. It's early days, but initial impressions are very positive. Grip in all conditions seems to be excellent, as does braking performance. I have not specifically rated wear (too soon) or handling (not tried anything beyond routine suburban and highway driving). The Subaru Outback is fairly softly sprung and the tire certainly complements that, giving an excellent ride. At first I thought the steering seemed a bit light and slightly flighty but then I discovered that the fitting centre had managed to get a 6lb difference between the pressures across the axle (in fact every one of the tires was at a different pressure, none of which were per the placard!). Having set the pressures correctly all round the slight lightness compared with the OE Bridgestone Dueler Sports remained, but the flightiness was gone. The steering is very linear and progressive and the car tracks true even in cross-winds. Note these are touring, not sports, tires and their characteristics (especially with a 60-profile side wall) reflect that. If you want precision, get Pilot Sports or Pirelli PZ4s which is what I have on my other cars. Initially the tires were not as quiet as I had expected, but they seem to be improving as they wear in a little. In any event they are a definite improvement on the Duelers in that respect. I have an impression that the rolling resistance is better, leading to slightly improved fuel consumption, which will be tested when we do our first long trip on these tires in a few weeks' time. Overall, I'm very positive, as I would have expected given previous/current experience on different cars with Michelin's Primacy ST, Primacy 3, Primacy 4 and Pilot Sport 2 & 4.
