So the two front tyres on our car had cord showing on the outsides of them.

What should I be taking away from that?

For what it's worth the rears were showing a "hair" of cord as well in the same place...

Oh, and I posted this here rather than in tyres since I figured this was more related to the setup on the car than the actual rubber itself, but please tell me if I did something wrong there as well... or perhaps the problem is driver [Smile]

Those cords are put there by Toyo to inform you that it is time to take the tires off and remount them with the threads on the inside......

......or throw them in the trash, which ever makes you feels safer.

Hard to believe that you could create a setup to cause that.

I know why the cords are there... but I too thought it was REALLY weird that that could happen...

In a related topic I heard someone say that the 1.6L cars wear more on the inside of the tires, and the 1.8L cars wear more on the outside. I have no personal data to back this up, but it's just what I heard.

But that's when they're the fastest.

My tires alway cord first on the outside, all four corners. If the overall profile of the tire doesn't look like a molded slick at that point you have an issue with inflation, driving style or camber. If the rest of the tire has worn evenly, then they are just running out of rubber and you can do as Muda say and get a few more heat cycles from them. I usually get rid of them at that point.

But my driving style is perfection embodied, it couldn't be that!! [Wink]

I can still see a bit of tread on the inside and very little in the center, but i'll double check that when I'm at the car soon (tomorrow I think).

If I can still see tread, how can I mod the camber more? I haven't even looked, are there camber shims on the Miata (at the hub to A-arm interface I assume) or is camber adjusted some other way?

Or could it be pressure as you suggest?
What are people running for cold& hot pressures?

Camber is adjusted by the cam bolts on the lower controll arm. Cold/Hot psi is 32/38. If you have not read over the jd set up guide you should read it a few times. This will get you a good understanding of the miata suspension adjustments. If I were you I would get the car to an alignment machine and see what your specs are. It sounds like you can get some more camber out of the car. I don't think that it would hurt much.

Have a great day,
Jared
