I believe that T.M. Tires still uses contact cement as well and it seems to work great.

An odd thing that we have been seeing lately are how some tires actually separate from the middle of the rim as if there wasn't any glue underneath but the T.M.'s have been very good with not doing this. As for the chunking issues, it seems that this can happen to everyone's tire, and as others have already noted, especially with particular compounds.

All in all, everyone (CRC, T.M., Jaco/Parma, BSR, TRC, RC4 Less, etc.) is making a quality product but it is interesting how different traction compounds (JTG, Paragon, SF, etc.) and different racing surfaces seem to be affecting the glues that different manufacturers use for their tires.

The best thing I have found for diminishing chunking is to really round off the edges, especially on the rears; this seems to help with what Ian brought up about the "slide and grab" condition that can occur in normal club type bite.
