If you're saying what I think you're saying, that you can't buy the OEM tires in the aftermarket, this is not really accurate, at least in my experience. It's very possible to buy the exact OEM tire that came on your car from a third party (like a tire dealer). One of the dead giveaways is GM's TPC, or Tire Performance Critera. This code is molded into the sidewall, and quite prominently, of most tires that comes as OEM on GM vehicles. When you see this code on a tire you're buying, you know that it comes on SOMETHING made by GM. Additionally, GM actually recommends that you continue to buy those same tires (with the GM TPC) for your vehicle when you need new ones.

Depending on the manufacturer, there are other ways to spot OEM tires (and to buy OEM tires if you really want that). Take, for instance, the Michelin Symmetry in 225/60R16 size. Go to
Michelin's website and scroll to the bottom. See those two 225/60R16 sizes? One's actually a P225/60R16 97S size, with a white stripe sidewall, and OEM on Ford. One's a 225/60R16 98T, with a black sidewall, and OEM on Honda. Part numbers are 98499 and 85237 respectively.
Okay, cool. Want that 98499 that comes on the Ford Panther cars? You can get it from 1010tires.com; check out
their website.
Sam's Club will sell you the 85237s if you like.
The Firestone FR710s on our 2012 Malibu at work, with the GM TPC SPEC 1323MS on them...you can't get a "non GM" version of that tire from Firestone. Every single Firestone FR710 in P215/55R17 93S size that you buy will be the very same ones that GM puts on the Malibus at the factory. Ford has its own OEM information. It's generally an F code followed by 4 or 5 numbers. Ford used to fit the Cross Terrain in P225/65R17 100T on the Ford Escape Limited. The previous owner of our CR-V had these installed, complete with the F code (because you can't buy a non-OEM version of the tire in this size). And their durability, predictably, was lousy.
You do have to be real careful when buying a tire model that also comes OEM on something. You may or may not be getting what you think you're getting.
Edit: I re-read your post again, and my reply. If you are saying that an OEM tire, depsite looking just like another similar tire of the same model, won't necessarily perform like that other similar tire of the same model, then please disregard everything I wrote above because I agree with you completely!!
