My 06 TW tires have almost 7K on them. There's a 1/4" of the center nubs left on the rear and 1/8" left on the front. Probably kind of dangerous to be running on them at this point. Can't really afford a new pair. Does anyone have a set with a little life left on them? Will take either/or. I'm ebay and paypal verified, near Laughlin, NV.
