The spec tire for the MX5 Cup (new pro spec miata series) is the Z214. That tire is the moulded tire (no tread pattern, but 2 grooves((thats what makes it DOT approved)). This is the tire we run on our Hankook tire sponsored Honda Civic Si's in SSC. These tires are as fast as Hoosiers in qualifying and faster over the race length. The Z211 is the tire with a tread pattern. This tire can be shaved for dry weather or run at full tread depth. The tire was designed to run at full tread depth in the dry so it will not chunck as some will in the dry. We run this tire as an intermediate tire. IT IS FAR SUPERIOR TO ANY TIRE AS AN INTERMEDIATE. We have backed this up with results. The most important factor is the compound. The compound is the same as the Z214. We use the C50 compound. It is the most desirable for road racing. The C30 compound is a little harderand is for use on rough pavement or for extended wear.
The heat cycling process is very critical. The tires need to brought up to temperature slowly and not abused during the heat cycling process if this is followed you will get many,many heat cycles out of a set of tires. I can direct you to my teamate, Joel Lipperini( long tire Hankook driver and multiple SCCA national road racing champion) jlipper@ptd.net. He can describe the step by step process of heat cycling these tires.
I would absolutely recommend the Hankook tires. They are far superior to Toyo and Kumho and better overall than the Hoosier.

FYI, there is an ad in the back of GRM for these tires....

225/50/R16 = $110
235/40/R17 = $118
275/40/R17 = $133

These are the "close out" prices being offered by Frisby Tire, Sierra Tire, and Aim Tire I'm not sure if that is a deal or not.

FYI bimmerworld.com also has them at "closeout" as well

I'm looking to buy a set of tire for track days, and I don't care about the last 10th since I will only do a few a year. I bought a set of 16" OEM wheels to use on the track, and at this price these look very good for my purposes.

All there is left out there are 225 for the 16" wheels. Is the small width in the rear not worth using them on the S? I most likely won't get as much oversteer as an AP1, and have some track experience. Any other reasons I shouldn't pick up a set of these for occasional track days? TIA

I wouldn't use skinny tires on the back.

But I'd bet you would still get a lot of oversteer. Regardless, try it out and let us know. There are plenty of people on here running none staggered, so the idea of doing it with 225's all around is not completely baseless.
