Yes they are high performance summer tires and yes I really enjoyed them but they are used up at 8000 miles. Frankly, they were used up 1500-2000 miles ago I just pushed them a little longer, driving them only on warmer dry days. The pic is of the front driver's side on a front wheel drive car. No auto X's or HPDE's, just daily driving. Any other's with this sort of experience? Since I have taken the pic all have been replaced with Michelin Pilots Sports.
8000? You're approaching motorcycle tire longevity there. That's good for a bike but not unheard of.
OE tires seem to either wear (and grip) like iron, or wear extremely rapidly. The original NSX's tires might last 3000 miles if you babied them, something about having a directional bias built in that stressed the front contact patches outward and the rears inward. (Four different, position specific tires per car)
In the late 90s, Volvo V70s came with tires that lasted about 10k before they were slicks. Working at a Goodyear retailer, we had a lot of complaints.
