Inner Tubes for Radials?

[Brian]

I've run radials on Kelsey Hayes wires on my 35 since the mid 80's. Because of the construction of these wheels, I've had to run tubes. The problem with 'radial tubes' is that they have a smaller valve stem, which necessitates running a plastic 'reducer bush' in the valve stem hole of the rim. I now run 'tractor tubes', these have the bigger valve stem that suits the rims, and they are of heavier construction....I've had zero problems with this combination. Incidently, I also run 'dynabeads' in the tubes, the fun part is the filling, but they are most excellent!!
