Mazda low tire tread depth after wheel alignment
So I got my wheels aligned in August but recently I got my car checked again at a different dealer. They informed me that my dread depth is low at 2/32 and that I should get new tires. I told them that I got my wheel aligned and thought that was supposed to help make my tires last longer. They said the dealer where I got my wheels aligned should've checked the tread depth instead of aligning it. So my question is, is it possible for tire tread to wear off in 4 months assuming that they were fine when i got them aligned? ( i commute everyday but no crazy driving). Because it doesn't make sense to me that I need a new set of tires now since everything has been fine.
