Thank you for considering our optional Certificate for Repair, Refund or Replacement. This program covers more than just irreparable punctures - if you hit a pothole/curb and put a bubble in the sidewall or have a manufacturing defect after the manufacture warranty ends, this is covered as well...
The retail stores do not have the equipment to do heat cycling at this time, but they do have access to that service for our customers when purchased through us.
I'm getting a 50/50 vibe on heat cycling the 555G2. Technically they do not need to be heat cycled, but I have seen better, more consistent results when they are heat cycled, according to other forum members.
Sorry that you had mileage issues, and your tires did not last as long as anticipated. I'm glad to hear that your local Discount Tire was able to get you taken care of. Thank you for your support!
