Metzeler tire question

[Ken_Ahrweiler@xxxxxxxxx (Kenneth Ahrweiler)]

List,
This morning I had a flat on my RT's rear tire. Been using Metzeler Z4
tires front and rear for years and have been satisfied. In the last year
or so Metzeler came out with a new Z6 tire line. Have been trying to get
some info on the new Z6. Went to Metzeler Web Site and can't come up
with anything. Can't even find a phone number for Metzeler USA as I'd
like to speak to a tech person. I was able to come up with some info
from one of the on line tire vendors that had a insert saying that the
Z4 was a steel belted radial. The blurb on the Z6 mentioned that it was
a radial but made no mention of being steel belted.

I've checked some of the tire vendors in the cycle magazines and I see
listings for the Z4 but not the Z6. 

Have any of you list members used the new Z6 tires or can anyone answer
any or the above questions including a phone number for Metzeler
????????

Anyone care to offer a suggestion on another brand that will work well
with a front Z4.

Sure would appreciate your help.
THANKS IN ADVANCE,
