While changing my All Season tires (with about 20K on them) over to my snow tires last week I noticed some wear on the inside edges of the front tires (more so on the passenger side where it's harder to avoid potholes etc...). This 14' Ford Focus has 67K and has never had an alignment done. My (maybe silly) question is should I remount the All Season tires when going for an alignment or can a proper alignment be done with the snows which show no wear on the edges. I know that only 'toe' can be adjusted but I'm not sure if the worn tires would make a difference in the readings that the shop needs to do a proper alignment. Thanks in advance.
