For tubes it would have to be much smaller to cause any problems...like a 23c tube in a 38c tire.
If your B.B. has no play and spins nicely without any binding it is prolly o.k. Quite often I have customers who think their B.B. is toast because it is creaking. 7 times out of 10 it just needs to be removed...the shell cleaned and greased and then re-installed. try this first...if it is still creaky after that then pick up a new one.also check yer chainring bolts and cranks bolts to make sure they are tight. Sham had a maddening creak that turned out to be one defective chainring bolt.
