I don't have any experience with the RE050A's, but the MPSS is a decently quick street tire on track before it overheats/disintegrates.

No time associated with the CR article, and the only thing I can find on the Sport Auto test is the forum post here which has zero information like if the compared laps were even done on the same day so as far as I'm concerned bunk, sorry. Unless I'm missing something?
Don't get me wrong, I don't doubt >1s can be gained with a tire swap to a streetable tire, my MPSS are about 2s slower than my RE71R's around a 40-50s autox course without changing anything else. And I'd bet the Primacy are at least half a second, maybe a full second slower than the MPSS.
The thing I doubt is "oh the Miata does so well because the Primacy's are shit *priustyrememes* and the Bridgestone were on the LFA so they must be great"
