Ah, I see. Hope I didn't come across as being critical, 'cause I didn't mean it that way. It's just that - geez, I never heard of 20 ply tires on a pickup! Well, they should do the job. Better than my 8 ply-rated, which survived an 11,300# (gross) load.
BTW what kind of wood is that huge load in your avatar? Is it a relatively light weight wood? Looks like enough to put the frame on the ground!
