Tyre opinions are always like opening a can of worms. Me and a mate both have the Cooper stt's and think they are great tyres. Dad and another mate run the Cooper a/ts without an issue.
My brother has the federal couragias in 35" and they have less grip than my Coopers.
Two other mates (with patrols) have mickey Thompson mtz's and while I reckon they are quite grippy, it's only because they're so soft. Man they wear down quick!

FanTapstic!
