My F550 did the wheel shake on the left front at 80 km/hr. Very annoying. I took it to the dealer and they said it was normal. I took it to a commercial truck tire place and they bead balanced it for me. No problem now!!
The beads cost $20.00 for a 19.5 inch wheel. Plus installation which they did without removing the tire. It's a cheap way to go to eliminate one potential issue and you get balanced tires. I was so happy I got the rear duallies done too.
