It begs the question, why would anyone replace the unique,
custom-designed OEM spec. tires with same-size generics on that
particular car?

The second used NSX I bought (to replace the one I stuffed through a
length of concrete fence posts backwards and sideways, but that's
another story) had Michelin Pilots, or some such, with a very sexy,
swoopy tread pattern on. They were nearly new, but I put the correct
Yokos on it and gave the old rears to a friend for the front of his
M3. The fronts went in the recycle bin.

I drove that NSX for a couple of thousand miles on the Michelins at
first, and I can assure you that they were the *wrong* tires for the
car. There was definitely a slingshot, lag effect with lateral
movement at speed, as opposed to the instant, firm shift with the OEM
Yokos and Bridgestones.

The tread ply angles are directional for each side, which is what
makes them left and right handed. Also, the sidewalls are *much*
stiffer than regular tires, but that's not a directional thing.

The OEM rubber compound is relatively soft, and is a different
hardness between the fronts and rears. All in all, it's silly to put
anything other than the purpose designed OEM tires on this particular
car, even if you have the irrational urge to rotate the tires and
things like that.

Mostly better tire wear.

The NSX absolutely had to have tires in good shape: right pressure and
adequate tread. It's absolutely twitchy/bitchy when they get worn -
handling
always improved with a fresh set. And you didn't want to drive it in the
rain
if the rears were close to the wear bars.

Yes, well, that's like buying Kraft cheese slices instead of good
cheddar. It's certainly cheaper...

Stock setting on what? The type of car would be helpful to determine if
it has any appreciable rear camber dialed in.

Well, I replied to the M3 comment...

OK so you're saying you have an M3 with 275 width rear tires, stock
camber settings and you don't wear the inner edges of your tires out first?

You are lying.
