37s are definitely worth it to me. On my 2012, I have mid perch & +2 deavers & stock wheels. It took an hour to bend back the rear wheel well pinch welds and trim the back of the front wheel wells. This picture is a bit misleading since the truck is in my driveway with an arch to it, making it appear the front wheel has more space than if it was level. It never rubs and there are no high speed issues, and it looks great & performs even better in the desert. I live in Big Bear & often drive off road in Johnson Valley, home of the KOH!
