I experienced new tyres that weren't balanced correctly several years ago. The fitter may have made a mistake or possibly forgot to balance the wheels. Take them back, explain the problem and ask that they check. A decent garage would be happy to show you they are balanced on their machine.

I would also suggest wheel balance. One of the glue on or clip on weights used to balance the new tyres may have dropped off.

But as a safety precaution before driving the car again I would also check the inner and outer side walls of the tyres for any bulges as a result of a manufacturing defect in the tyre structure. Its very unlikely there will be.
