Miata Tire Tech Column

In March of 2017 I was complaining about a vibration between 45 and 55 mph. I had put the wheels on the balancing machine during tech day and discovered that two of the wheels appeared to be out of round of slightly bent. I proceeded to have them straightened, by Stevenson Mazda (thanks Howard) – which by the way was cheaper with the club discount than if I’d taken them to the wheel guy myself.

The straightening seemed to work but there was some concern that the Falken-Z912’s tires may have been worn unevenly. Since I knew I was about to need tires anyway the Falkens were 19,000 miles old and the wear bars were becoming visible. They had been a great performance tire, very sticky and very responsive. But I don’t tend to drive aggressively so I was looking for an improvement in wear, ride and especially noise.

Howard (Stevenson Mazda) hooked me up with a full set of General Altimax RT 43 Grand Touring tires (for my Grand touring Miata).  He was able to beat the Tire Rack price so I was thrilled. That was 18 months and about 6,000 miles ago. I can tell you that the Altimax RT 43 tires are a lot quieter, a little softer ride, a little less responsive (but my driving style isn’t especially aggressive so I don’t care). They make driving the car more enjoyable for my copilot without diminishing my fun quotient.  At 5,000 miles they still look new so I’m guessing that they will last longer than the 19,000 miles the Falkens turned in.

Okay, so we haven’t been out driving much this year but my tires now have 10,438 miles on them and they have been great as far as I’m concerned. Quiet, comfortable and seem to be wearing well(see picture below).

My top replacement, 3X and counting… My rag top has now been replaced three times due to rips at the pull straps that help fold the top when putting it down. That means I now have the third new replacement top. I thought all was well when (Play the music from Jaws) I found this…

SOFT TOP REPLACEMENT So, this top replacement was actually done by a shop in Wilmington. If anyone wants to know how to do it yourself there are lots of videos on the Miata Forum. Most admit it takes over 20 hours with no prior experience. Mine took two hours; one hour to drop the car…
