Perhaps your observation about the tube being a bit too big is the reason
that I managed to mangle mine the first time I did the assembly (or perhaps
I'm looking for an excuse for my clumsiness).
Your query got me digging into my Aircraft Spruce catalog which confirmed
the source of my confusion. Although the catalog lists "Tires & Tubes" with
a description that mentions both Goodyear and Shin in the same sentence,
upon a closer reading it appears that only Shin are available in the
11.400-5 size. Before preparing this reply I checked both the Goodyear and
Michelin web sites and could find this size on neither (and I looked for
industrial and golf cart sizes too), so I guess we're stuck with Shin. Or
Sears - read on.
When I needed the replacement for the damaged tube I researched the tire
size and found that (as mentioned in the Aircraft Spruce catalog) this is
not an aircraft tire size, and I further discovered that it is available
---From Sears for their Craftsman riding lawn mowers and lawn tractors. When I
mentioned this many months ago on this forum it prompted an immediate
response from the factory, so I'll note now that the main gear do indeed use
real aircraft tires (and it is those sizes that are much more expensive than
the Michelins on my car.)

Hi! Rob.
Are you saying that you can actually get a Goodyear tube that fits the nose
wheel? If this is so please provide details and source? I'd prefer to change
mine since I'm convinced that the original tube I have is too large when
fitted correctly , on inflation the slight oversize of tube material has to
go somewhere resulting in small folds in the walls which flex and self wear.
The UK supplier agrees that there seems to be a problem ,having done a trial
assembly , but says there is no other source. BTW out of interest to other
"listers" my a/c although it has never flown with the mono system was
constructed to take either/or system of main gear.

I must have been thinking of the inner tube I bought when I chopped the
first one full of holes the first time I joined the two halves of the nose
wheel. When I found out that a Goodyear TUBE would have cost me almost as
much as a new Michelin TIRE for my car, I bought the cheap stuff.
Fortunately I learned how to mount the wheel without damaging the tube.

These ones have 'Made in Taiwan' molded in. Or am I missing your point?
