I have decided to purchase some 37x12.50x15 IROK radials, but no one seems to be able to get any for the next 3-4 weeks. I was hoping to have the K5 up and running again by then, but if I can't find tires then that is not really a possibility. If anyone has some 8 lug wheels and tires that they could loan me for a few weeks, or better yet, if anyone knows somewhere that has IROKs in stock, let me know. /forums/images/graemlins/ears.gif Thanks guys. Or... if you can think of a comparable tire that you would recommend, let me know about that too. I have gotten an overwhelming recommendation for the IROKs from multiple people. The truck will be mostly offroad, but will have to drive freeways to get to the offroad spots and is my only form of transportation. I want to keep it in the 37x12.50 range due to the lesser mass and my having a D44 front. The truck will be parked mostly during the week and wheeled on the weekends. Mostly mud, muddy trails, and snow trips up to the mountain to offroad and ski. No rocks. Possibly sand. Thanks Again Guys! /forums/images/graemlins/waytogo.gif 4.10 gear ratio.
