Took my parents car in for an alignment and it came back good. A month later they needed an oil change and tire rotation. Oil change went fine but after rotating the tires their alignment is off. Yes I could have just rotated the tires back to see if it would correct it but I asked the shop whats the deal. The tech said to rotate them back and it should fix it.
If this is the case and it fixes it..."good" but the tires should still be rotated. Ive never come across this before
this. once they get a wear pattern or w/e, theres no saving them regardless of alignment, they’ll continue to wear that way.
if the issue continues i would say next time you need tires, get an alignment on the way
