With the wheel off the truck, check how the cone for the 9/16" lug nut fit in the wheel. Its not hard to see from the back side. If the wheel is sitting on the cone part of the lug all the way around the lug, it should be OK. If the cone part is still outside of the wheel, its a no go. The cone part of the lug is what the wheel makes contact with and centers the wheel. Often times, the larger stud has lugs with larger diameter cones that won't fit into the wheels, then the wheels won't seat correctly and won't tighten correctly. Gene
