Inner Tubes

[mike.smith]

The original inner tubes I bought for the standard Sonex main wheels had the valve stem centered in tube, along the center inside seam. I'm now only finding tubes with the valve stem off center in the tube. That means the valve stem is not aligned with the centered hole in the wheel halves. Does anyone have a source for inner tubes with the valve stem centered? I've looked on Amazon and done Google searches but haven't found anything.

Not much help but a guy in Australia can get them. The buisiness is called 'Wagga Bike Tyres'... freight will hurt you though :(

In Illinois I found them at Tractor Supply store. I was unable to find them anywhere else with the size and type. in other states you might want to try farm supply type stores. I think these tires and tubes had some other use on small tractors, wagons or something before they became tires and tubes for a Sonex.

I tried these last time since they are "Leakguard" tubes. For some reason one of them lost a lot of pressure over a couple months. I've since reinflated it and it's been fine, so not sure what happened.
