Marathon Mfg Change?

[SRW]

I was told by a AS owner that Goodyear changed the way Marathon's were being manufactured sometime in 2006.

he was told they started adding an additional membrane to prevent tread separation.

I would like it to be true, but got to wonder.

Anyone hear anything about this?

On the outside, the Marathon Radial features a rounded profile to enhance ride quality,
and a symmetric tread design with a solid center rib to provide constant rubber-to-road contact
that delivers dependable highway stability, traction and long lasting wear.
Internally, the Marathon Radial features twin steel belts
(with selected sizes reinforced with nylon cap plies)
that stabilize the tread to increase traction and durability.
The Marathon Radial features a polyester cord body to help smooth out the trailer's ride.

the canadian (2005) and chinese (2006+) versions do have a differently sidewall SURFACE rubber and graphics...

but i don't see any mention of a nylon cap in the sidewall wording...
