Yes.......

 

Thanks guys, that didn’t take long ! ​​​​​​​

 

Thanks @2008f250xlt Here is what that spit out, confirming that I have the math correct. It is showing that I could pull a 11,760lb Fifth wheel with 800lbs of people and gear.

 

When I purchased the used 20” rims and tires, they had 8,000 miles on them. There was some slight cupping on two of the tires and I assumed they were front tires. The thing is, when I measured the tread depth, there was more tread on those tires. Is cupping a thing on rear tires? I’ve never had that on rear tires before on any truck I’ve owned, or is it possible the rears wore more that’s the fronts?
