Embodiments of the invention include methods and apparatus for constraining a tread in a desired arrangement about a tire carcass during retreading operations. Such methods include the steps of providing a annular tire carcass configured for receiving a tread. Such methods also include the step of arranging a tread annularly about the precured tire carcass in a desired position to form an assembled retreaded tire. Such methods further include the step of arranging a retread curing membrane about an outer side of the tread, the curing membrane including an interior surface arranged to engage the outer side of the tread and including one or more protrusions extending from the membrane interior surface and into a void of the outer side of the tread. In other embodiments, a separate insert containing protrusions is arranged between a curing membrane and a tire tread for retread curing operations.
