in this video the new tread is formed like a big rubber band and put over the carcass:

and in this one the tread is cut from a sheet and wrapped around it. I think this is the type we see all over the highway...

I wonder how the reliability of the two different methods compares.

I’m sure retreads are cost effective for large truck tires but I’m not sure about car tires.
