I have a 1989 R100GS with spoked wheels. I had a dealer put on a set of Metzler Karoo Street tires. The rear is holding air, The front stopped holding air after a few months. I tested the wheel/tire while the tire was still on the wheel and there were several small leaks at various (random) places around the wheel (bead of the tire). I took the front wheel back to the dealer who said there was corrosion on the wheel, the tire wouldn't seal and recommended putting in a tube which I authorized.

The bike always is kept in the garage and it is not subjected to temperature swings here in the Sacramento, Ca. area.

Is this "normal?" Is there something that could be done to the wheel so I can run the tires tubeless reliably (which is my preference? Should I put a tube in the rear to be safe?

Appreciate any advice.

Best,

Jack
