Poor Performance with Conti Sport 3's

[brad]

How does a toe issue cause more wear on one tyre than the other on the same axle?

camber of the road. For RHD counries, if you don't give them a fraction more -ve on the left to compensate for the road camber then you have to "steer" up the camber of the road. If you have toe-out then the RH wheel tends to wear a bit more on the inside; toe-in & the LH wears a bit more on the outside.

I have never seen a wheel alignment where there is specifications for left and right toe. There is only a specification for total toe. For example a SAAB 9-3 has a total toe of .28 degrees on the front. This equals out to .14 degrees on either side. Now you could adjust the toe on the left to .18 and the toe on the right to be .10. However because the car wants to drive straight it will naturally counter that and make it so that there is .14 on either side and the steering wheel will be off centre.

I never said to set the toe un-evenly - that would give a crooked steering wheel because the wheels self-centre.

I said the wear is caused by the camber of the road - you have to steer into the camber to maintain a straight line, therefore if you have toe out, the LH wheel tends to run straight ahead & the right hand wheel is the one pointing up the hill keeping the car straight - which causes it to wear on the inside more the the LH hand one.
