kale, before you get yo panties all in a bunch, check your tire pressure.

 

Have a good look around and if they reset the rear they are very finicky. Can show straight but when loaded by driving it will take a new set. Look into it and see if the rear before and after are noticeably different. If so they probably need to get it back on the rack and reset the rear. Front is probably OK, but I bet the rear is Wacky a bit.
