I don't care what the process is, its still a USED tire that has a new tread physically glued on. Like I said, on a non licenced off road rig, seeing slow speeds and what not...sure, on a rig driving on the highways etc. they should be illegal. Blow out from a poor "glue" and I have a 70mph projectile in the form of some cheap ***'es rig flying at me and my family. There is NO WAY that these retreads are as structurally sound as a complete new tire. I call bull**** on anyone who says otherwise.
