Well I ordered a set of 5 today! They have about 1/2" tread left and are re-groovable another 1/2 inch if needed.

560.00 shipped to my door. I am buying them from Michele Knautz in Canada. Her number is 450-424-2399 and her e-mail is "Michele Knautz" <mknautz@total.net>.

I'll let you guys know how it works out.
