Wraps are a tire made by jaco. What they do is take a very hard foam and wrap the rim in it. For example on TC tires the rim runs 49mm, with the wrap of harder foam it brings it out to 53.5mm. Your tire actually starts then at 53.5mm. The harder foam under the regular foam allows the tire to not have as much bite and help free the car up alot. As well as give you more forward bite due to a bigger contact patch.
Parma has already released there version of 12th scale foam that has a larger rim, not sure the exact size on a 12th scale however there new TC tire has a rim diameter of 53mm making the wrap a thing of the past for parma users!
