I heard about this last week and had to order the rear tires. I'm getting one, and the wife is, so we'll end up with two sets. I did this promotion on the Diablo tires two years ago, and it worked out well. I'm just hoping we get our tires (tomorrow), and get the paperwork to them before they run out of the fronts. They got rid of 80 tires since Friday afternoon.
I've been redeemed. I just got this email from my source:
Thank you for your inquiry. Every retailer, including ourselves, that sell Pirelli or Metzeler are Parts Unlimited dealers considering this is the only company in the United States who distributes these brands of tires.
Yes, we are Parts Unlimited dealers. Please respond if you have any further questions. Thanks again.
Looks like you're covered unless you get them from ebay.
