Rear tyres worn on both inside.

[Antony Wells]

On inspection I have found that both of my rear tyres are worn on the inside, car has done 160K.

Have I a bush problem, I haven't got a broken spring.

If the tyres are worn on the inside edge then either you have excessive camber (where the wheels are pointing inwards at the top when viewed from behind or the wheels have excessive toe-in

Either way it is advisable to get a four wheel alignment check carried out to determine the cause of the tyre wear
