This is not and should not be debatable. Every single clear reference easily shows the S07 as the tire that was produced by Bridgestone for the FD. My manual has an insert that is called '1993 Tire Information', and IT says the tires were supplied by Bridgestone, Dunlop, and Yokohama. It goes into great detail about the specially constructed, ultralight carcass yada yada yada.

Old S02s that have many heat cycles can be dangerous when cold. Be careful pushing the car even just driving around town. My car came with some old s02s that had plenty of tread life left but they were hard as rocks and would lose grip in the rear at 15 mph in a turn.

So let's see it. Your claim isn't good enough.* (And you mean to say if Bridgestone tells you they never produced an S-07 you won't accept that? LOL!)As I've said all along, this mistaking a 1 for a 7 is a common misperception in this case. You'll find many mistaken references, but a reference is not a fact. I urge anyone here to do another simple Google search. Enter "Expedia S-07 Mazda".* What you'll come up with is a number of amateur web postings, individuals referring to an S-07 tire. Now enter "Expedia S-01 Mazda". What you will come up with is a number of commercial sites mentioning the S-01 tire and its specific application to the RX-7. If my copied and pasted links below work you can see for yourself. The first one is the official Bridgestone website. It should lay to rest any question that there is, was, no such thing as an S-01 tire. http://www.bridgestonetire.com/tires...nd=BridgestoneBridgestone Expedia S-01********* Category: Performance Original Equipment (OE) tire on select vehicles. See Sizes and Specifications for Original Equipment fitments. View Product Pagehttp://coastalcarparts.com/product-B...aS-01Tire.html"Bridgestone Expedia S-01 Tire priced from $190.00 to $260.00. The Potenza RE-010 and Expedia S-01 are considered by many to be the state of the art in original equipment ultra high performance tires. The Expedia S-01 is used on the Mazda RX-7, Porsche 911/928/968/911 Turbo, Ferrari 348 and F355, Mercedes Benz C36, Aston Martin DB7 and the Honda Prelude VTEC.

The Potenza RE-010 is used on the Toyota MR2 Turbo and the Acura NSX."http://tiresmart.net/BridgestoneTires.htmHere's a listing of all sorts of Bridgestone tires including the S-01. Scroll through the whole list. You won't find an S-07. http://www.capamerica.net/bridgestoneperformance.htmAnother commercial site with a long list of Bridgestone tires including the S-01 but no S-07. *You can go through all sorts of publications and websites and come up with all sorts of typos, misperceptions, and misinformation.* (Are you still seriously contending that Bridgestone produced an S-08 tire?) The trick is to separate the wheat from the chaff.
Every one of those links shows CURRENT production or stock. Take for example, the Bridgestone RE71 that was sold from sometime in the 80s through well into the 90s; do you see it on that list?* Does that mean it never existed? In your mind : "Nope. If it ain't on that last it only existed in peoples' imaginations." By the way, if there was a "71" then, according to your preaching there couldn't possibly be a "70" now....but magically there is. Years and years after the 71. But once again I point out the fact that the S-01 (and nobody's denying their existence, so you can quit your endless tirades) and S-07 were EXPEDIAS and the S-02s and S-03s were POTENZAS. Not that it makes any difference as I gave you the 71 and 70 example above, so things DON'T have to all be chronological.*You keep typing about "misperceptions", mistakes, and typos. Nobody here ever disputed an S-01 existing- evidence is everywhere. Once again I say that NOBODY HERE EVER DISPUTED AN S-01 EXISTING. So you can quit arguing that point once and for all. You're the only one, despite every single kind of evidence stacked to the ceiling, who has misperceptions about there being no such thing as an Expedia S-07. You're wrong. And you lost.

A rational person : "I seem to remember it was a D40, though my memory's a bit foggy."
Somebody else : "LOL!! The maker of tennis racquets and sports clothing also putting rubber on your car?! What next, same company that makes EVOs also produces TV sets? Yeah, right!"

This has become a stupid debate. Very often OEM tires are special to the car, sometimes they are designated with same number as after market sometimes not. The '94 R2 came with Pirelli P-Zero Asymmetric, was it the same model that you could get at the tire rack, no. Believe me in 95 I asked after 4000 miles on my car. While I would need to dig out my sales brochures for the ’93 RX-7, yes I have every one from ’82 to ’95, plus some mid year ones.
I would firmly believe that Mazda/Bridgestone specified a special Expedia S-07 for the R1, playing on the "7".
Both Car & Driver Feb ‘92 and Motor Trend April ‘92 call out this model on the R1 tests and mention this model in the tables and text. Autoweek and others do not list make/model titres. Yes I have every english language road test on this car starting with 1991 intro and yes even some german car test reports.
Road & Track Apr ’92 sped’d a regular model with w/ Yokohama A-022A and I have a Mazda ad showing Dunlop’s, can not make out model.

Enjoyed reading this silly debate! Guess what guys, my 93 FD R1 with 20000 miles still has the original rubber-Bridgeston Expedia SO-7,s. Yea, yea I know they're hard as stones, but being the cheap Scotsman that I am, I'm still trying to get a few more miles out of them. If you want, I'll donate them to the RX-7 museum!

bslrg, probably one of the last original tires out there, man.
I swapped mine out a year and a half ago. Car had around 12,500 on the clock and the rears were well worn. All four were definitely, shall we say, out-of-round anyway. Driving it off as if some minor flat-spotting just didn't alleviate it. But I figured that after almost 14 years it's time for fresh rubber.
Anybody else notice that the modern tire technology of today isn't so great when it comes to letting tires sit for more than a week or two and not experiencing flat spotting? Also those old S-07s didn't seem to change their structure anywhere near as much when temps dropped below 40, unlike what I see from current Bridgestones.

So, let me get this straight. You are contending that both an S-07 and an SO-1 tire were put on the FD, is that correct?
OK, show me both the "7" and the "1" script on the sidewall.
Did they look different? Did they look the same? And if you can't tell the difference between the two doesn't that tell you people were mistaking the 1 script for a 7?
(And that's not to mention the absurdity of the claim that this speciality SO-7 tire came on the base model car.)

No one here has produced a primary reference. Show me a verifiable Bridgestone tire catalog showing an SO-7 as distinct from an SO-1 and I'll send you $100.
Let's go back over the claims again. The contention of my opponents seems to be that there was a specialty tire called an SO-7 that was distinct from the SO-1 tire that came on many FD base and Touring cars. (Other sizes of this SO-1 also came on Porsches, Aston Martin, etc......apparently they weren't good enough to get this "SO-7".)
This SO-7, so the claim seems to go, was available only for a limited time on the RX-7, then it disappeared from the marketplace.
Now the funny thing is, the SO-1 continues to this day....in sizes never available on FD rims. You can find this SO-1 listed in current Bridgestone catalogs. (There's nothing about an SO-7.)
Yet, when you look up this SO-1 tire on the Tire Rack website they list a special notation for SO-7. Now why do you suppose that is? The alleged specialty SO-7 for the FD is long gone, and the current sizes don't apply to any FD rim.
There's only one logical conclusion: a continuing confusion in mistaking the stylized 1 script on the sidewall for a 7.

Kind of a schizo marketing plan, wouldn't you say? Why not just make them all SO-7's?
And the funny thing is, it's the SO-1 tire that carried on.
Lots of claims in this thread and the citing of secondary sources. I've produced a link to a Bridgestone catalog showing an SO-1 tire. Anyone have official Bridgestone literature / documentation / catalog showing the existence of an SO-7? Does it show a distinct SO-7 model tire, or is it a conflation as in the current Tire Rack website?

It's an SO-1. You're right at the heart of the confusion. A one script with no horizontal line at the base of the stem. Confusion that continues to this day with an attempt to resolve it on the Tire Rack website.
Here's something else to think about. What happened to this "speical SO-7" tire?
Come 1994 on the R model Mazda switched to Pirelli. The SO-1 continued on. I know. They came as original equipment on my '95 and I bought a replacement. I still have the receipt. It clearly says SO-1. These were V rated tires. They came on many base, Touring, and PEG cars from 93 through 95.
So what happened to this alleged SO-7? You mean Bridgestone tooled up for this tire, creating a special sidewall stamping, had this great tie-in between the "SO-7" and the RX-7 and it only lasted one year while the SO-1 continued on (to this day)?
No. There was only an SO-1. V-rated on the base and Touring, Z-rated on the R model in 93, then switched to Pirelli.

LOL !!!!! I'm getting the biggest kick out of this. It's getting to be Alice in Wonderland.
That's a photo I posted ! Ha, ha, ha. Go back and look at post 40. I have the original catalog from which it was scanned.
This is a photo of a base car. They came with V-rated SO-1's. There's at least one person who is claiming they got this special "SO-7" on their base car. You mean Mazda was generous to this guy that day and it was all the other suckers who got the V-rated SO-1?! LOL!
Some people aren't sharp enough to pick up on the contradictions that have been exposed.

Another little thought experiment for you having to do with post #40 I wrote.
Go back and look at the FD specs. You'll see V-rated tires came on base and Touring models. R models got Z rated tires.
The sidewall photo I posted in post #40 showed a '93 base car. It would have V-rated tires. Most are willing to concede that SO-1 tires came on some FD's. Yet at the same time they're are swearing that the photo I posted shows an SO-7 sidewall.
So what are you left with? You mean Mazda was putting V-rated SO-1 and SO-7 tires on the same car?! Why the duplication? And if you're claiming the SO-7 was only a Z-rated tire that came on the 93 R-1 then what's it doing on the base car you see in the photo I posted?
