While I have no way to see exactly what leveling system you have on your 2006 Tiffin Phaeton 35DH, I was able to find information on a forum showing someone who did confirm the SnapPad HiWay 10 Jack Pads for HWH and Atwood Leveling Systems w/ 10" Round Jack Feet # SN58FR were the correct ones for his. You can verify this by first ensuring you have either a HWH or Atwood leveling systems and the jack pads are 10" in diameter. I ask that you verify as RV manufacturers often switch parts throughout... view full answer...
The tires and wheels we carry are only for trailers unfortunately, and they actually only go up to 17-1/2" wheels.
You'll need to reach out to a local RV dealership or automotive tire/wheel shop to get a spare for your motorhome. view full answer...
