Ok,

I've heard you talking about treadwear ratings of 200 and 500, and it would 
seem that the lower treadwear coincides with stickier tires (well, duh.)

But here in New Zealand, I've never heard of these ratings, are they 
specified by the US DOT?

I just checked my tires, (Falken FK-06G) and they have treadwear of 280, 
which I guess makes them fairly short-lived and fairly sticky, but on the 
same panel it also says Traction A, and Temperature A. I also checked 
several other tires in the work car-park, most tires did not have any of 
this stuff. (My tires are made in Japan, for an international market, most 
of the company cars have NZ or Australian tires)

Can somebody explain these ratings?

Yours, curiously..
