I owned the Cooper STT and they where a EXCILENT mud tire with great millege out of them i put just over 38000 on them and took them off, i wanted a A/t now. those tires saved me in mud so many times i cant remeber, they also take giant potholes like a chap
. if you want a mud tire from cooper look no farther they are great. If i ever wanted another mud tire I would get those agian!!
