Just wondering if anyone has tried reinforced filament tape like this:

It has fiberglass strands running through it and is almost impossible to tear. I have always had to use a razor blade. I would think it with some of the other tires would offer the properties of a 1:1 steel belted radial. Especially if the tape was applied then backed with a liquid rubber glue type compound. Could probably be used with the 40 series road rage and still kept fairly light.
