The picture shown is from Manny Macmillan and his Plum H1 Open Top.
The Wheels in question are Eagle 589 alloys in 16.5x12. I used to run the exact same rims on my H1 before AM General did a warranty flag on my truck while I was running them. I ended up selling them to Manny because he ran the exact same rims.
Yes, beadlocks would have helped.
And Manny knows how to drive. Look at some of his past runs here:
