I forget what it took to get the rubber stabilizers into two of the eight little round holes in our wheels. Wasn't easy but I don't remember having to lube them.
Speaking of soapy water, Our custom rear stems must have been properly installed (Loctite discussion above). Still had the 75-psi I'd set them to nearly four months ago. Another shameless plug for custom stems!
But the Spare was Flat! I found the nut was loose on the non-custom metal stem, after rolling it into the pool and finding the bubbles. The fronts, with the same valve stems, were still at the 60-psi I'd set there, but I think I'd better go check for tightness.
