Question about alignment job..
 

I am about to get 4set of tires and check my front tires and they seems to be okay for couple month. But my rear tires thread is almost gone. Especially my tires are more worn out on inside. It's almost flat! on inside the tire.

So my questions is, I will be only replacing just rear tires, and getting the alignment done. Will I need to do another alignment once I replace new front tires?

No.

:tiphat:

the inner tread wearing a tad faster is normal on our cars... so you may not need an alignment.

honestly just swap the fronts too if you can only get a couple of months out of the fronts.

Thank you for the information. I will need to find out see if there's promo for tires.
Also, I will do alignment check before I do this... Thank you!
