Never done one before, but got it figured out pretty good... It is actually a very good design, with the only drawback today being the lack of parts...;((
BTW, I have another post about parts wanted... Some have to do with the torque tube... If you could gloss it over, I would appreciate it.
I guess if you want to work in the barn you have to start the fire at 6.00 am!..
The actual height of the Goodyear R-3's is 30.75" with the weight of the truck... You loose close to 1" without any of the weight... The other tires I purchased are 31.50" and are now mounted on the closed cab truck... I think I will purchase 6 more for lack of anything else... You can see the two tires side by side for comparison... The Chinese deal I had for 12 of the other sand tires similar to what I got went south when it got complicated with the usual stuff...
I'm moving slower than I would like to, but inching along... At least I have a running vehicle with a torque tube. On to the brakes.
