Need more info. Is it constant or just at higher speeds? You may have thrown off the tire balancing weight which will cause the tire to shake and make steering more difficult, Look and see if the balancing weight is attached. If it is, this is more likely a ball joint, tie rod or stabilizer link issue as they keep the tire and steering stable.
