Q: Rear driver side tire is slanted, causing wear on the inside.

Hi, thanks for writing in. Camber on the rear wheels of your vehicle is not adjustable. Your vehicle was set up at the factory with fixed negative camber in the range of one-half to to 1 degree although values as low as 0 degrees (i.e., no camber) are acceptable for certain wheel diameters. With negative camber, the top of the wheels are leaning inward (again, by design) which lean will tend to wear the inside tread of the tire, just as you are observing. Regular rotation of the tires, every 6,000 miles, tends to minimize that effect. I would ask the shop if your camber exceeds 1 degree negative. If it does not, then the solution (to tire wear) in your circumstance is more frequent rotation of the tires. However, if the camber exceeds 1 degree negative, the suspension parts are worn, bent or damaged because camber was set at the factory based on OEM parts. If camber is no longer within the allowed range set at the factory, obviously one or more parts has worn out although it possible the frame could be damaged, too. Before considering aftermarket fixes, you have to confirm that there is no way to restore the measurement to that which it was built with originally. If you would like help, consider having an expert automotive technician from YourMechanic come to your home or office to inspect your vehicle for you and speak with you about what’s going on with the car.
