Wobbly back wheel

hey guys loving the board so far - just after some advice - my back left wheel seems to wobble a little when under power more so than the right - it looks like the wheel might be slightly misshapen? It also sounds as though it has a slight rub. Worth taking in for a look or are these things fairly common?

Cheers

Take the wheels and swap them, see how that goes.

Then if that doesn't work try taking the wheels apart and putting them together again.

The wobble shouldn't happen on GT's only on the older versions.
