IRS alignment setting for wide rear tires

[Sandeep]

I finally have the rear end together with brakes, fenders and wheels. I drove the car down the driveway and back to settle the rear suspension so I could get a camber measurement .. it turned out to be -2.93 degrees

The 265/35/18 rear tires are only contacting the ground on the inner 3/4 of the tread (I saw the tread tracks in the snow). When I had the 195/65/15's on, I had fine tire wear but got a big problem now.

All of the rear bushings are old and I plan on converting to urethane in the next few weeks. The rear is lowered about 2" and I'd rather not re-index the spring plates. Does anyone have any suggestions as to how to correct this ? :help: Does anyone have any alignment settings for wide rear tires ?

Thanks for any suggestions.
