I've been told by a tire salesman that because my '01 CR-V is AWD that I
need 4 matching tires and cannot mix brands. I cut the sidewall on one
which was low on tread anyway but really only need two. Is the 4 tire
advice true?
The original tires on a '01 CR-V are no longer (readily) available.

If true can anyone recommend replacements? 205/70R15

Thanks
