Short version: I have just installed adjustable rear camber arms and would like to know what the ideal rear camber is for long tread life. I do not care about handling as this vehicle is strictly used as a highway cruiser.
Long version: My Ford C-Max came from the factory with rear camber of -2.2 degrees on the left and -2.4 degrees on the right which were both within Ford's acceptable range of -2.4 to -0.9 degrees. This car has already wore through the inner tread on all four of my Pirelli P7 A/S+ tires in under 40K (rotations every 10K per the manual.) which I believe was caused by the negative rear camber. I installed some adjustable rear camber arms myself and when I got new tires mounted I asked my local tire shop to dial the rear camber in for ideal tire life they set the rear camber to -1.4/-1.5. Does anyone think that my new rear camber measurements will help with my rear tire wear issues or should I dial it in closer to -0.9 or possibly even closer to 0?
