Hmmm toe seems good. Maybe you should check your bushings, tie rod or ball joints are still good??? Not sure just throwing a guess since your toe is not aggressive.

 

I have no idea if caster can destroy tires though.

 

Sorry I forgot this thread. Your caster is probably off because of your moar low. I forget but I dont think that affects tire wear, but it drastically affects handling. Toe is simple, just unlock and spin the tie rods in the front. In the rear it's just an eccentric.

The machine will tell you where the settings should be.
