Today I started cleaning the wheels. The extra wheel that I have will be my spare. It has some dents around the rim, and I’m not sure how serious it is.
First off, I ripped out the old valve stem. Then, with an angle grinder, shaved-off as much as I could of the underside of the rivets. Then I drilled holes in the rivets. This may have been unnecessary. I used the grinder on the front of the wheel, and ground off the rivet heads, then punched them out.
Finally, I used the wire brush attachment on the angle grinder to clean off the rust and grime.
