normally I would say camber doesnt wear tires, toe in or out does, but are those bias ply?

if so, cant run much camber on a bias tire, it will wear out like crazy, the way the plys are aligned in the tire needs a low camber installation, because the more uneven the ground pressure is, the more force the bias tire puts on the side with the higher ground pressure.

if they are radials, have you replaced the front end components on the s10 chassis? worn bushings will hold in place for an alignment and then the road force pushes them back, like your hand in the wind, leading to super weird wear patterns.

hope this helps!
