Rear wheel wobble

I've a Whyte 901 2015 and I just repaired the rear tyre. When I refitted the wheel ( and yes it is positioned correctly) I noticed it wobbles. It was whilst I was pumping the tyre and was just squeezing it, it has a sidewards wobble. Now it might have wobbled for ages and I've just not noticed. It has a Whyte 21 wheel. I'm not in a rush to change the wheels. Is there something basic that I should be doing. I suspect it is going to my LBS in a couple of days. If the hub is damaged, is it replaceable or will it just be cheaper to buy another wheel?
Cheers

    Who can say?

    What wobbles? Wheel or tyre?

    Is the wheel buckled?

    The tyre not seated properly?

    Wheel not fitted properly.

    Bearings worn?

    What did you repair - the tyre or fix a puncture?

    It’s not clear what you actually mean by ‘it wobbles’.

    Do you mean without it rotating it can be moved from side to side, do you mean when you spring the wheel it’s not true and you can see the tread ‘wobbling’ (although that’s jut really wobbling) from side to side?

    Thank you for your responses and sorry for my lack of clarity.
    I replaced the tyre as I'd had too many punctures and it was time for a change.
    I turned the bike upside down to replace the wheel and after I thought everything was secured I grabbed the tyre to feel the pressure and the wheel moved from left to right. Its' not obvious when spinning (it doesn't look like it's buckled) but if you hold the wheel it definitely moves.

    I'm guessing it is something to do with the bearing but it's not something I have ever had to replace, (or truth be told service). Hubs and bearing s always feel like a dark art that I have stayed away from.

    So the bearings either need adjustment or replacement.

    Are they cup and cone or cartridge bearings?

    Or is the QR not tightened up?

    QR its definitely tight enough.
    I will tackle it today and have a look at the bearings with a reference to youtube.
    I'm fairly practical but there are parts like the hub I just don't touch. Is it something I should be able to do, or is it one of those jobs to leave to the specialists?

    pretty straight forward to sort out, what rear hub is it?

    shimano are cup n cone and you'll need to regrease it and adjust the cones so the ball bearings sit correctly - will need cone spanners for this. something you might not have in your toolbox.

    other hubs are usually sealed cartridge bearings that you can carefully tap out and replace with a new one of the same size. bare in mind with these type, there is also sealed bearings in the freehub but usually its the main axle bearings that wear on these.

    Have you located the axle in the dropouts correctly? Not trapped the cone spring etc. It doesn't take much.

    But I agree with what has been said before that it is probably the wheel bearings.
