Ok I'm looking for a set of 46s for my truck. I was going to use 44" boggers but I have to use a 20" wheel with my brakes from USA6X6. So do I go with 46" Michelin XMLs or 46" Michelin XLs? I know both can be grooved. I'd be running them on either USA6x6 20x11 Double Beadlocks or Stazworks 20x12 Double Beadlocks. This truck will be used for mud, trails, and street use. Very few times will it encounter rocks. I just want to know which will perform the best and have the best characteristics.
