three possible things it is:
1: your wheel is cracked. new wheel is necessary.
2: your bearings are fucked. new bearings should do it.
3: sometimes when your wheel is too tight, it clicks. loosen your wheel and you should be good.
Bearings or it could be a soft wheel. thats happened to me before the wheels was soft as from tire taps and it just squeeked but i changed it and the bearings and it was all good.
