Speaking of center caps ... OCD episode 462:
When I swapped wheels to the Yukon and put the new caps on, one of them won't fit tight on to the wheel and it sinks into it like 1/4" all around. It's not an issue with the caps, we tried all of them and they all did that on that one wheel. I'm not sure what would do one wheel not take the cap tight, but there you have it. We were pretty stumped by it actually.
So I'm wondering if there's a 'fix' for this ... I was actually thinking of putting a thin strip of clear double sided tape around the edge of the cap to hold it in place.
