Valve stems for outer tires
This is slightly related but may be of interest. I had no problem with the braided valve extensions for the inside tires but could not for the life of me get a tire gauge or air hose into the opening for the outer tire. It's a real knuckle buster in that small opening! I ordered some right angle valve extenders but those did not fit in the opening so returned them. Finally, a tech at a tire store suggested I get "gator" valve caps that allow you to check the tire pressure and fill them without needing to remove the valve covers. For some reason, this little change gives me just enough room to fill and check the pressure. Still very tight but possible if you get just the right angle. Hope that helps...
