for some reason, my bike has the knurled nut on one tire and it doesn't have it on the other. I haven't had to change the tubes or tires yet, so I couldn't have lost it, the LBS must have only put on one as some kind of sick joke.
But I haven't had any problems with either wheel, I'd say the nut doesn't do anything. But I can see how it could be useful when using a pump.
