I just got my car aligned. The only 2 specs I'm a lil worried about is

1) the rear right camber is 0.0 degree (rear left camber is -1.1)

2) front right caster is -0.1 degree (should be between 0.7 -2.7)

should i be worried about those? or are they ok? I dont want my tires to wear away quick, will those specs make them wear faster?
