As a follow up....The C rated tire says on the sidewall--tread 3 ply polyester, 2 ply steel, and 2 ply nylon. Sidewall 3 ply polyester.
I suspect this is for more puncture resistance, not load carrying,correct?
No, I don't think so.
I suspect the 3rd body ply of polyester is there more for marketing purposes. Many people think the same way pnichols does - that more plies are better - and that is not lost of the tire manufacturers. Adding an extra ply adds a bit of manufacturing cost, but might result in a HUGE markup.
The 2 nylon plies are for separation resistance.
The fact that this makes the tire every so slightly thicker would result in less punctures going through - but I don't think the difference is enough to worry about.
