Greetings, when I got my new 2012 F-350 last fall, one of the first things I did was remove the wheels and coat the back of the wheel mating surface with never-seize to keep the wheels from corroding to the hub. When putting the wheels back on, I couldn't lift them
Thought I was getting weak in my old age, but then decided to weigh them. Each wheel weighed 105lbs!
The only thing I can think of why they weigh so much is the wheel and tire must weigh 25 pounds, and then the 80 pounds of air make them 105.
Seriously, I know they are the 20" aluminum wheels but would never expect them to be that heavy. A couple years ago I bought a set of hydraulic wheel lifts from Harbor Freight. Glad I had them because the wheel lift made easy work of putting the wheels back on. The wheel lift also allows you to rotate the wheel to align the lugs with the holes. Thought I would pass this on in case there are any more weaklings out there beside me.
