On my wifes tahoes over the years, I've put the Dodge factory type...goodyear wrangler hp tires (same size and brand 100%) but from a tire dealer, and the same goodyear eagle Ls2 that gm used on 20"s (also from a tire dealer). Both goodyears were junk tires. I hated them and had so many broke bands with over half tread.
Ive had nexen tires on her most recent tahoe with 22's and they are doing great. My tire dealer buddy says they are almost as good as Michelin tires.
Maybe they arnt as good in a solid axle configuration?
I would try another alignment shop, and not a firestone. Ask at some bodyshops who they use. We have to go over to a firestone that our shop uses sometimes to show them how to align some of our vehicles. The cant figure stuff out if it doesn't have an adjustable cam on the bolt or have threads to adjust. Solid axles take someone that knows thier stuff, not a newby that just got out of a Hunter class.
