wheel balance problems

That *is* the 65-mph shimmy. Imbalanced wheels excite a chassis resonance at 60-65 mph, plus a bit on either side depending on how badly they're out of balance. Note that that's an actual 60-65, and on a Miata the indicated speed may be up to 5 mph higher. You cannot eliminate the car's tendency to react to imbalances, but you can have the wheels balanced more carefully.

Try a different tire shop, one with a Hunter GSP9700 balancer. Try this page:

Practically every every service place within 10 miles of me seems to have one EXCEPT the Miata dealership. :-(

For the record I had this done with my '04 and it made a huge difference.

I see Firestone is the closest non-dealer.. would you trust them to do the job? I try to avoid them almost as much as I avoid Dobbs.

HI, Scott. It's the individual technician that makes the difference. I got a great job at a good price from AutoTire in Sunset Hills, (314)

Thanks for all the help.

I sent an email to the local rep (I'm from Canada so that search site doesn't work for me) to locate a garage. In the mean time, if somebody can recommend a garage in the Toronto area, that'd be great.

Thanks! Victor

Because of the Ford Explorer debacle? That's a bad reason to avoid Firestone, IMHO.

Um, no. I'm didn't say I avoided Firestone tires.. the discussion was about service shops. I avoid having my car(s) serviced at Firestone because I don't trust the quality of service.
