Most likely you have a bent wheel or worse yet, a bent rear axle.
Many cars have independent suspensions that need to be aligned on all four, not just the front two, Saab is one I can think of.
Slamming a curb or some other violent hit to that wheel could cause the wheel to toe in.Have the car aligned, the service center will know to do a 4 wheel alignment.
yes
Improper tire pressure or a bad toe out. Take it to an alignment shop.
Tire toe alignment means that the tire has to be aligned with the "toe" of the car which is the shell that covers the car. This allows the tires to be easily adjusted if needed.
usally a disc in your back
yes. but the biggest preventatives are proper tire pressure and alignment angles (toe, camber)
Could be a bearing going bad.
A toe back is really a touch touch backhandspring. After you land your toe touchjump right into your backhandspring.
Camber and toe can both cause inner tire wear.
Assuming that there are no worn parts in your vehicles front end, the cause could be excessive toe-in. Have the front end alignment checked.
not enough potassiun
No toe could not grow back its impossible but a toe nail can grow back i think you have to wait 2 months for your toe nail to grow back
No. Low tire pressure causes poor handling and poor tire wear.
