The wheels on my somewhat recently acquired Hi-Rider are in terrible shape. I suspect the bike was left to sit in a shed with no floor and over many years of sitting on bare ground the wheels sunk to a degree into the dirt. They will eventually be replaced but for now I'm replacing the rear tire, tube, rim strip so at least it will hold air, and at some point transfer it to the wheel with a new rim. Upon removal of the old tire, which by the way had to be the stiffest, most time hardened tire I've ever had to remove, (had to actually cut the tire off) I see that it has a tire/rim lock. Were these original to all commandos? These were something that I used to see used on the rear tires/wheels on motocross bikes, but have never seen them used on street bikes. Mines in sad shape, like the wheel, and I'll have to see if a replacement is available from some seller. Are they really needed, other than filling the hole in the wheel that was put there for their installation?
