[QUOTE=Kardec;904763I had Alcoa over the road wheels on the ER and they were so tight that changing a 140 lb tire/wheel was a disaster yet now I run the +/- 200lb Hendrickson/Continental tire/wheel combo and, amazingly, you can get them on and off the lugs much easier because the spec is ever so slightly looser. You actually don't have to put as much physical effort into it. Best to think of stuff like this ahead of time ... I sure didn't but it can save you time and money. Heavier is more awkward in more ways than one.[/QUOTE]

Have you had any front wheel bearing problems yet? The stock tire and wheel on the front of a F550 is about 90 lbs and has a different back spacing than your >200 lb wheel/tire combo you have now.
At least my Unimog came from the factory designed for 340 lb 395/85R20 XZLs.
Are you aware of any front wheel bearing problems in ERs with the Continentals?
