Ok I have a 87 blazer stock engine, some upgrades(cfm-tech stuff, headers, dual exhaust, k&n...) I am running 1 tons with 4.56 gears locker in the rear and a six inch lift and this thing is my daily driver that sees some rock crawling but will be seeing more down the road. Right now I am running 35'' pro comp x terrians but they are getting bald. I want to upgrade to a larger tire but keep it street friendly. My thoughts are 37'' ssr or iroc but I am also entertaning thoughts of the 39.5'' iroc(radials only) not that much more expensive. Well give me your input(pros, cons etc.)
