Absolutely. Almost always toe is what kills the rear tires. Usually when a ball joint or bushing fails that allows toe to change under load so it looks ok or even let's you set toe properly. Then under braking acceleration or cornering the toe changes (and apparently almost always toe OUT) to scrub the inisde of the tires.

Here's the evidence to back my understanding:

I have had nearly 3° neg camber for years and able to wear tires to the wear bars the entire width.

Then suddenly a couple months ago I notice inside wear. I figured I have a worn rose bushing or other ball joint but I'll be replacing tires with tax return so I'll last a month or two.

That's a big negative. Tires wore through to the "redneck wear bars" (steel belts) within two weeks. With no measurable change in camber that's been the same for years.

It's not camber.

I will mention I normally take curves at 1/2g. Every time. Maybe 3/4g when feeling a little spirited, so the camber is negated (posated) on the heavily loaded outside wheel.

If you only drive straight and turn at 1/10g, then camber will have more effect on inside wear but still won't be as critical as toe not ever.

Under inflation will have more inside wear effect than camber.

I will show just how bad my toe is affected by the worn parts in the back. I'm about to replace every arm, bushing and ball joint in back. I will be surprised if I can't push the wheel to 1/2 to 3/4° outward toe. (considering spec is 0.15° inside toe that's horrific)
