The morning after my new 22.5 tires were installed, I was removing the cap to check the air pressure when the RF valve stem broke right at the base of threads and the end of the stem including the valve and the cap disappeared into the cosmos... (also lucky I was not in the way).
Tire dealer sent repair truck, he raised the front wheel with the leveler, used a jack stand, broke the bead and put a new stem in without removing the wheel or the tire. I was impressed...
The brass valve stems were new!!
