2017 JKU - I just ordered some big new tires BFG KM3 in 37x13.50r17 rated E - now I’m wondering if E was a bad choice and if I should change it to 37x12.50r17 rated D. I want the best off-road performance, on-road doesn’t matter. What would you guys recommend? Does the 1in extra width make up for the little less flex? Using steel 17x9.5 rims.
