any suggestions
 

just put the new wheels on and went for a ride and i hear a knocking noise when i take my foot off the gas to slow down and also when i put the clutch in any suggestions on what it could be?? and help please

are all the lug nuts tightened down all the way?

thats all I can think of too

did you buy hub centric rings? Do the wheels need them?
Sometimes if the wheel bore is large enough it might do that.
