Yes it can cause wear but usually it's wear on the inner edge. Bad alignment is the number 1 culprit for excessive tire wear. Jack up the vehicle and grab the tire at the top and bottom and wiggle it aggressively and feel for ANY play.
Or take it to an alignment shop, they will know immediately if there's a problem.
