( race cars.. yea... )...... For a while, I worked for the Corvette guy, Dick Guldstrand ( Burbank, Ca)...... He aligned the rear axle on my '88 GMC truck. I didn't 'hit' anything, but after years of driving, it needed a little adjustment.When i’m at the track (in the race car, not the tahoe, haha) I can get that same pattern if I scrub the tire too hard and overheat the rubber. I think it’s called graining. I would say that is indicative of a previous test drive peeling out around a corner more than of anything else. As others have said the tires have dry rot anyways so you’ll want to replace anyways. As for the rear of the Tahoe, it’s a solid axle so there isn’t any camber adjustment to be had.
