Well, the Exalto/Kosei's are on. I've only had the opportunity to run several miles down the mountain road towards town, but they feel much quicker. However, they shipped with 35.5, considerable higher than the 32-r/29-f which Mazda recommends. I think I may reduce pressure to 32 lb and see if the ride improves even more.

It will....  afro

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...

I will - when I get the vibration problem worked out.  If I hadn't mentioned it, I live on a mountain top in a 3.5 acre thicket...   rolleyes

I hope the vibration is a balance problem and that you didn`t mistake a bent wheel for a more serious problem.
Keep us posted.

I also, Steve.  I'm at a loss to understand what else it could be, in the rear end.  If the vibration were in the front, I'd have several candidates...

I hope you didn`t damage a half shaft in the hole in front of the Mazda dealer.
Can`t people sue the city for stuff like that?

Thing about it is that I already had one bent back rim, and vibration, from some pothole in Huntsville.  I bent the second one over in Decatur, 20 miles away, because the dealership here was in the process of being repurchased by the dealer who had it up until 3 or 4 years ago, and there was no service department in operation here.  It's back open now, teamed up with his VW/Audi dealership, so maybe there'll be more service resources.  I had a little Mazda B2000 truck I bought from this dealer back when he had Mazda before and I didn't like the attitude of the service dept.  It's been my experience that the employees in a dealership pretty much reflect the attitude of the guy at the top.  Nevertheless, the dealership is the next stop if re-balancing doesn't solve it.  Tire Rack is paying for the rebalancing.  I took it first to the nearest approved shop, a Goodyear store, where they have a Hunter GSP9700.  However, that guy said that Miat tires always need to be balanced on the car, since they're so sensitive.  (Hell, I'm even beginning to worry about the theft-proof lug nut).  He suggested one of the Michelin dealers with an on-the-car machine.  I called Tire Rack again and they said they would reimburse for any Michelin dealer, so that's where I'm heading this afternoon...

I thought spin balancing on the car was a thing of the past. I can remember when they used to shave the tires while they were spinning. They don`t still do that do they?

It may be in somebody's past, but not in mine.  I drew an old codger who stood about 6'1" and weighed, maybe, 125, if you counted the cigarette hanging out of the corner of his mouth.  He spun the front tires up - no vibration.  He moved to the right rear, and I climbed in to rev it up.  As soon as it started up, the car started vibrating.  We worked on it for about 30 minutes.  At one point, we'd covered two miles and I commented on it to him.  He said "sometimes it takes five."  Finally, it got it to "one more try."  (He'd already answered my question as to whether there were Michelins that simply can't be balanced in the positive).  The last try, he got about 90% of the vibration out.  The left rear had no vibration - smooth as silk. My dilemma now is whether I accept the 90% or demand that Tire Rack take it back and send a new one.  Remember that three out of four were perfect.  There's also the possiblilty that the right stub axle is out of true and he just balanced out the harmonics.  This shop has seven bays, with two devoted to spin balancing on the car.   The other five have Hunter GSP 9700 machines.  The spin bays cost $10 more, have a two-day waiting list and require an appointment - significant?  The shop manager stopped by and informed me that "we do all the SCCA guys, all the Miata racers."  I think I may have stumbled onto a winner...

Couldn`t you have switched the rr with the rf and ruled out anything other than the tire?
