I would sure like to see the alignment measurements. Often with oversize tires the caster is decreased on the left side to overcome the general tendency to go right. This then appears as a small brake pull when the car does as it should with such differences.
Also the toe often changes greatly during braking. If you let that package get toed out during braking everything else will be magnified tremendously.
The front suspension was not designed to handle the forces of such tires (or the weight). You will always be living a compromise.
