Haha! what a small world! You are correct, apparently close to 9000 lbs on a 5 lug axle with 5/16 studs is to much! Unfortunately my dad and i were out of town when it happened or we would have just run over and put a couple new studs in it and limped it home. also unfourtonatly ,the towing company thought it would be wise to stare at it for 10 hours while scratching their heads
they then proceeded to load it on a couple car dollies with old cracked tires. they made it a mile or so away and the dollies gave out. The cherry on top is that they are threatening to charge us for the damage to the towing equipment in saying that we did not inform them of the large weight of the vehicle.
The funny thing is, our new '09 dodge cummins 4x4 weighs over 8500 lbs and they seem to tow them just fine... hmmm Needless to say we were not very impressed with this towing company
