Welcome and thanks for your question. My name is XXXXX XXXXX X am here to try and assist your with your question
Molded tire are way better than retreads. They heat the material up and mold it together and so far I have heard no complaints about them coming apart. It is a cheaper way to get new tires.
Retreads have concerns and are used by fleet trucks. They tend to come apart. If you are looking for a cheap solution to getting tires I would not worry about buying a set.
Thank you, XXXXX XXXXX what I was told at the repair shop, but got confused when I researched it on the web.
