2007 Suburban Alignment ?s

[mdavidthomas]

I have a 2007 Suburban LT 4WD with the 20" wheels. I have ~48,500 miles on my truck and the Bridgestone Alenza HL are worn out on the inside edge. However, the only reason why they need to be changed is because the inside of the tire has worn down and blistered. The outside edge of the tire has plenty of tread left. I brought this up at my last dealer oil change and of course they wanted to do an alignment. There was very little change in the spec's after the alignment and the service writer said the Tech told him I was getting normal wear as far as mileage on these tires. He also stated that the inside tire wear is normal for the suburban with 20" wheels. Here is the before and after alignment specs. (Unfortunately, after weasling $70 more dollars for a alignment, I don't know anymore than I did before the alignment......I always feel dealerships are getting a 2 on 1 fastbreak on me!)

 

So, before I get new tires, is there an alternate or updated set of alignment specs, any tsb's that could be referenced?

 

Thanks in advance for your help.

I can't make heads or tails of the allignment readings you put up. It's impossible to tell what number goes with what heading.
