A quick run to the LBS got me a couple of the
metal type of adapters. Put those in from the tire side a la the instructions on the
Park Tools tube page [search text for "adapter sleeve"]. Only thing is that, per the instructions from the LBS guy, I set the metal sleeve in the rim hole first and then pushed the valve stem through.
So far I have 85 PSI in there, which is the max the tire can take. Let's see what happens.
I thought you had box style rims typical of 27" wheels. In that case, you may have been right, maybe those grommets just don't work on those type of rims. So you got the metal ones and they work, great. I put my grommets into a box style rim I had on my 85 Schwinn Le Tour Luxe and they work perfectly for that rim style. Heck, I didn't even know they made deeper aero rims for schrader valves...I guess I bit behind of the 27" rim technology!!!
