Depends on what is wrong. Did you check the tire pressure? A low tire will cause the pull, too, and will get noisy when it gets really low.
A belt coming apart in the tire will do the same thing, especially if it is separated on one side only. Tire tends to track funny when it has a larger diameter on one side than on the other.
Belt separation is also usually accompanied by various rumbling, roaring, or slapping sounds and considerable vibration.
