I could, but it didn't occur to me until I was driving away.  The tech cautioned me, when I rotated, to mark the theft-guard lug nut.  He said that it was heavy enough to unbalance the tires.  I found this curious, since Tire Rack didn't know where I would place that nut, when they ballanced the tire.  I do plan to swap the tires and see what happens...

Later. I don't have them on this machine. However, I've got a vibration in the rear problem now. TireRack is paying for them to be rebalanced locally, in case that's what it is...

Did you make sure your rims where torqued to 85lbs? I had some vibration when I installed my Racing hart for the first time.. I had them @ 80lbs torque, checked with dealer they retorqued it to 85lbs and problem gone for ever.

What's your wheel offset? I'm looking at some 15x7s with a +40.

First, yes, I installed them with a torque wrench.  And, Ran, the offset on the Kosei K1 Racing is 38.  There are only a few brands which won't fit over our brakes.  Here is one link to which won't, comment by Goodwin Racing.  If you log into miata.net, tires and wheels, and enter "fit" "brakes," you'll turn up a bunch of threads.  When I contacteTR's CS, they immediately said that the tire was out of round and shipped out a new tire, which hasn't arrived yet.  They pay for M&B upt to $20 per wheel...

Tide:
I hope you get your tire today. I`m curious as to your problem. It`s pretty unusual for Michelin to produce a bad tire, esp. in a high-end performance tire. I hope that`s your problem and not something mechanical.
Keep us posted.

SA, it's on, balanced and the problem seems to be solved.  Of course, I'm so sensitized now to vibration, that every little bump which causes "cowl-shake" makes me think it's coming back.  Do they have any perfectly smooth blacktop down there in LA?  I'm going to try to find a recently repaved strip around here somewhere, so my mind can be completely set at ease.  On Michelin and OOR, this is actually not the first one I've had.  However, their rate is far below the other manufacturers...

Are you using stick-on weights on the inside of the wheel or conventional weights(that scratch the rim)?
The stick-ons aren`t as good, but they sure look better.

So far as I know, the stick-ons are the only ones the Kosei's will accept.  So far, the vibration still seems to be gone.  I have the normal Miata cowl shudder, but the roll bar helped with that...

I don't really remember at this point, but, at some point real soon, I'm going to pull the right rear and put the OEM back on, because I'm still having a vibration problem on the right rear, not as bad, but noticeable.  The only two possibilities are the wheel and something further up the drive train.  The OEM combination is around 36 lbs.  The present combo is considerably lighter...
