I was swapping the all-season tires for Winter tires on the new-to-me 2010 RAV4 last night and noticed that one of the all-season tires that came with it had more tread depth than the other three. I know some AWD vehicles are very sensitive to variations in tire circumference and this would be a no no on them. Is the RAV4 one of those vehicles? My owner's manual does not mention this as a problem. Just curious.
