Abstract

The present invention relates to new and novel tire construction and method of making same wherein the uncured elastomeric material that is laid upon the tire building drum during building of the tire preform will not experience substantially meridional stretch which would otherwise cause a decrease in the uniformity of ply thickness during expansion of the preform in the vulcanizing mold.
