There may be more than one reason. First we need to check the air pressure in the tyres-it has to comply with the norm. It is also necessary to look at the wheels of the wheel as well as the unevenness of wear and tyre. If the car has been in an accident, the cause of the water may be disturbed by the geometry of the suspension or bodywork.
Other reasons may be broken wheel balancing, incorrect corners of the break/cayings, eating one of the springs, wear on the sainting blocks of the back suspension beam, and a single wheel-wheel following a failure of the braking mechanisms.
