Those of you that have bought Tread Wright retreads, how many miles do you have on yours and what is the current tread depth?

I was wondering myself so I went out and measured mine. I'm sitting at 7583 miles on them and they have 14/32" of tread. From looking at the web site they came with 16/32". So I've lost 2/32" or 1/16" in over 7500 miles? I'm thinking they might just make it past the 20,000 mile warranty.
