G'day team,
when I was a little boy they used to have retreads. Are these actually retreads but with an up to date U.S. name?
Good luck with them if they are. They were cheaper but you didn't get new tyre mileage out of them and they were prone to delamination. Can say, 'been there, done that'.
Maybe though that was then and now a different technique is used and it's better.
Dunno
