It looks to me that the super single tires mounted on this truck are too large Once the truck is loaded and going over uneven ground and the tires are flexing it appears that they will be rubbing against each other compromising the power and speed of the truck . These trucks were initially designed using 900-20 dual tires on the drive axles leaving space between the axles. Now in your following video of the cargo truck there is a space between the tires making the use of these single tires appropriate. If anything the dump truck should be equipped with 11:00R-22.5 radial luggers n my opinion
LOL, the suspension is 4 link bars, wont ever rub. and these can carry about ((14,000 pounds)) per tire, and do it all day off road with low psi. Also with the small tires, it tops out at 55 MPH red line.... low range is still plenty low . those skinny RAMBO first blood era tires are tube type, and these are radial and have steel belted side walls. with a hydro boost steer, at 25 psi,these things will smooth out the ride and allow wy faster speeds on rough roads... Might not be as (quick) to fwy speed, but I think it's a better set up all around.....
