I just purchased my first new Wrangler, a Sport S with 17 in. wheels. The tires are Goodyear SRA street tires which I want to change for another set in the stock 255/75r17 size. The Goodyears are listed as 36 lb. When I look at other tires like Goodrich t/a k02 at 46 lb, or cooper st maxx at 55 lb. I have concerns about what the extra tire weight might to to my steering or suspension components. How much if any additional tire weight might I be able to handle without endangering my steering or suspension components?
