It's okay I just ordered some tubes with a regular size rubber valve teats to avoid butchering the wheels. These wheels were made in my home town from the mid 1970's until maybe 1985. This is the 4th set I've had in 30 plus years but they are hard to find now - this pair took 5 years! These have had a tyre fitted but have never been used. Old and Heavy, you bet ya, but I love 'em
Cheers
