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.

Pneumatic tires and method of making

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 subtantially meridional stretch which would otherwise cause a decrease in the uniformity of ply thickness during expansion of the preform in the vulcaninzing mold.

A very light weight tire 10 has at least one radial ply 38 and a rayon belt structure 36, having two single cut belt layers 50, 51 covered by an overlay 59 having cords 80 selected from the group of aramid, rayon, PEN, PET and PVA. The tire 10 has a very thin or reduced gauge (t) undertead 13. The tire 10 can be made having very low rolling resistance due to the combination of casing structure and the reduced rubber mass.

Low cost light weight radial tire

Light weight aramid radial tire

A very light weight tire 10 has at least one radial ply 38 and a fiberglass belt structure 36 covered by an overlay 59 having cords 80 selected from the group of aramid, rayon, PEN, PET and PVA. The tire 10 has a very thin or reduced gauge (t) undertead 13. The tire 10 can be made having very low rolling resistance due to the combination of casing structure and the reduced rubber mass.
