I had a set of eagles B--4, on my 02' 7.3L F350 SRW, "They would explode not bend, explode or CRACK APART on Impact from road debris and other items. So they will need 2 be replaced occasionally,
Forged or Billet CNC rims can B Repaired most of the time. 20x10 should fit with a leveling Kit and the right size tire. Only Time rubing items other than fender walls is an issue is when....you Change the Rim Width and make the Rim Wider w/o at least adding a leveling Kit,"which by the way is what you have" .
No Leveling Kit on a SuperDuty + Wider Than OEM rim width, will = suspension scrubbing on tires.
That is why they many times offer 20-22" Rims in an 8.5"-9" Width. These would fit a non-leveled Truck w/o Suspension Rubbing. Therefore 22x10 or 20x10 will more times than not (Usinng Factory Bakspacing) Need to have the Minimum of a Leveling Kit in order for those Wider Rims to be able to be mounted w/ tires and Not Rub.
I run 325/65/18"s or 35x13.5x18 w/ OEM Ride height No Rubbing under full Articulation , NO LIFT. Stock Stance ,Stock Rim, BIG Rubber.
PS: I Know they are More Money, but for our Super Duties rating payload capacities, we all should be running D.O.T. Weight rating requirements when looking to relpace rims and tire packages. Hope This Helps..
