You most likely need an alignment. Take it to a shop

 

[HoustonGT]

Your alignment is off. Have them rotated and then have your alignment done

buy new tires for the front and get an alignment. Most places will not do an alignment without the new tires.

what year car? check the alignment, could be out, usually caused by worn suspension components if it hasnt been modified.

you either have alinement or balljoint issues. jack the car up and see if there is play in the wheel. if there is repalce the parts. If not go get an alinement.
