So I this isn't a jeep question. But I just got a 1989 ramcharger with a skyjacker 6" lift locked front and rear. It has a set of Goodyear wrangler MT/R's 35x12.50 the old styles non Kevlar. With about 50% tread on them. And my dad said he'd trade me for a set of 80% tread Dunlop mud rovers. Well. I want what's gonna be best. How do the old style MT/R's do?
