Rear tire to floor clearance?

[justduck]

Hi all,
I'm wondering about the minimum tire clearance that I can use between the tire and the camper floor using a 35" SRW. With the mounting system I'm planning there shouldn't much box movement over the wheels. Scaling up the diagram in the body builders PDF for max deflection for a 35" tire I get 8.3" above the frame. I'm thinking 10" should be plenty, even allowing for the possibility of having to chain up - which seems unlikely.

I don't have enough weight on the empty flatbed to deflect the rear springs enough to get a measurement. I don't want to allow more clearance than necessary, but I sure don't want to find I didn't allow enough. Any input from those with experience would be appreciated.

I'm sure that there will be many more questions before this puppy is on the road.:coffeedrink:

I think the only other consideration would be the rear track dimension and the actual radius of the tire.

The rear axle bounce height shown in the manual is for a 32.6" tire out the width of the outside dual wheel. Most calculator show the diameter of a 235/85 16 tire as 31.7"

I had to use chains on my 93 FG on the Morrison Jeep trail near YNP in July in the mud.

Good Luck
