...... If I want to air up the tire without removing the discs, I'll have to cut an access hole in each one. The discs can be mounted with velcro for easy removal, then they can be solid all the way, but I'll have to take the wheel off to air it up. I'm thinking a circular hole won't look too bad on the discs.
What about a 90 degree valve extender and just poke the extension out to one side and maybe put it in the same color as the disc so it is not as noticeable but serviceable at the same time. Just my 2c worth!!
