I see that the left rear tire on my '97 855 is getting kind of bald. I found a screw in it some time ago and apparently ran too long before getting the problem fixed.
The right rear still had a goodly amount of tread on it although it certainly is not new.
Do I need to replace BOTH rears at the same time? I have hard this advice for *some* cars but wonder what the A.A.V group has to say.
