2008 Volvo C70 Question: Rear wheel alignment causing tires to wear prematurely.

 

Question

Visitor, 2.5L 5 Cylinder Turbo, Morristown, NJ, April 12, 2011, 11:23

The inner shoulders of the new rear tires on my 2008 C70 are wearing prematurely. I want to change the alignment specs to minimize this wear. I don't drive the car in sport mode and don't care about any loss of handling. What specs should I use to realign my car?

    this is normal tire wear for most European cars, like Volvo, MB and BMW. this is called negative camber and it is
    not adjustable; this is the design of the car and you cannot change it. if you use a non-directional "H" rated tire, it can be "flipped" to extend tire wear. directional
    tires do not wear or perform well on any Euro car.

    Thanks for your reply. I changed the rear camber on my BMW. This resulted in even tire wear and no noticable difference in handling (for the way I drive). I'm going to buy the aftermarket camber kit for my Volvo. Can you suggest the number of negative camber degrees I should remove while still maintaining a minimum negative camber? Thanks again.

    Do you happen to have the printed alignment sheet from the last alignment?
    According to my manual the rear camber should be -1.72 +/- 1 degree.
    By driving the car in sport mode will not change anything on the suspension or steering geometry, so it won't cause uneven tire wear.

    The factory specs usually don't cause premature tire wear. I suggest doing an alignment and based on the readings we can decide what is going on. Anything else is just an opinion.
    Do you have the old tires for us to examine?

    Thanks for your comments. I just found a Volvo technical service bulletin titled
    "Uneven tire wear, Correction of excessive negative camber" reference # US15309.4.0 en-GB. This lists the steps to take and the parts needed in order to correct the rear wheel camber. Thanks again.
