Obviously it shouldn't be so bloody dirty (soon to be fixed!) but should those 4 trapezium-shaped holes be empty? I've seen wheels (not off NC's) with those similar holes and they have pieces of rubber that go in the holes..
If I am supposed to have them, will it hurt not having them? And where can I get them from?
Also, can anyone tell me what size the rear wheel nut is? I didn't have a socket big enough so had to use an adjustable wrench with a breaker bar but it kept slipping off and I ended up damaging the nut (whoops!)
Lastly, when I tighten the rear wheel nut, do I have to do it up as tight as it was before (had to use a long piece of pipe to break it) or just as tight as I can get it without the breaker? (the R-clip will hold it in place as well, and the nut should tighten itself when the wheel is moving, right?)
Cheers
