Rotational noise from N/S/F area Renault Clio Expresion 1.2 16v (2003)?

car made a clonking noise and then started to make a rotational type noise, almost sounds like a flat tyre ! tyres checked ok as are brakes, seemed to also have a burning smell just after the clonk but may have been coincidence, noise seems to get louder/worse the longer the car is driven, any ideas ? car still drives straight and pulls well under acceleration
