Besides the prior reasons given, there is another. If running radials and one hits a pot hole, bump, curb or the like, hard enough, the impact can compromise the bond between the steel strands and the encasing rubber, in the area of impact. You won't be able to see it or tell in any way, other than while riding. The air pressure, along with the bond keeps uniform tension throughout the circumference of tire allowing for stability. When that bond becomes inconsistent, a shake can be initiated. This off balance shake then can easily induce a wobble. The tire is ruined and replacement called for.
