Michelin primacy mxm4 p235/60r18 tires with a little over 13000 miles that came new on 2013 acura rdx. would not stop on a slight down hill road that was damp. starting stopping at a safe distance but all they would do was slide and skid. stopped finally with front of car slightly in oncoming lane. just as i got stopped a dump truck went across in that lane right in front of me. not the first time i have had traction problems but the first time i almost got in serious trouble. these tires are not safe on wet or damp roads. *tr
