New tubes for 11x400x500 tires on Azusa

Hin Guys,

Replacing my tires on my Sonex which have the standard Azusa wheels that have the \

hole in the center for the tube.

The current tubes have the valve stem in the center of the tube. However after ordering

the same tube from AircraftSpruce I find the valve stem NOT in the center.

Has anyone found a vendor with the correct made tubes???

Bob,

I bought my last set from Sonex. I did find this:

I’ve bought small engine parts from them before, I think.

Edit: found this too.
