Aaah! The joys of unemployment. Being a creature of habit, I woke up this morning primed to go to work. With the kid off to school and the wife set to go shopping, I headed to the barn for a few hours of solitude. I decided to clean up the HUW fuel tank protector plates and to dismantle the spare Prototype wheel.
The plates were an easy fix and are now hanging in the barn waiting for the paint to dry. The spare wheel turned out to be easier to dismantle than the run flat – it only took 15 minutes to remove the outer nuts and separate the split rims from the tire – without damaging the tire (which will be used as a “yard tire”).
The interesting thing is that the split rims were held together by 10 nuts and bolts and two studs and bolts. For some reason someone removed the studs – the weld marks are still visible – and replaced them with bolts. Has anyone else found this kind of arrangement on CMP rims?

Upon inspection of the rim, I spotted some stampings. They looked different from the other stampings, so I got out a wire brush was surprised by what I had found.

I think the stamping reads: RF, then DUNLOP O, followed by HA 9.00 – the rest was defaced by corrosion.
I am guessing that RF denotes Run Flat. I am not sure about the “0” after Dunlop, or the HA stamping. I am assuming that 9.00 refers to part of the tire size. Any thoughts?
