Just finished building my need bike up and ive noticed a wobble on the front wheel, the wheels have crest rims and the tyres where really tight getting them on, could i have pulled the rim out of shape or have i just got a dodgy wheel. they are hope hoops 29er wheels btw.

More likely the tyre’s not seated – have a look to see if the fitting line near the rim deviates at all.

You won’t have buckled the wheel fitting tyres.

I agree with the above. If the rim is buckeled it is a spoke tension issue.

Remove tyre and rim tape and check rim for cracks (just to be sure).
Spin wheel if there is significant wobble you will see it.
Refit rim tape and tyre and tube.

Or just refit the tyre as 90% of the time this is what it is.
