i really doubt the state will allow the 12k axle to go that far.I did heavy haul [ up to 200,000 lbs ] for 20 years. I know about pushing things to the limit. You take some states[Tn,Va] will give you 24,000 lbs on the steer axle. That's 12,000 lbs on a 6,000 tire. Don't tell me about stupid!! I have not nor will not push anything that far past the limit. Even if it is legal. Ben knew he was not safe and didn't pull it. Hats off to him!!
there are 25k axles and tires to match. I've driven those monsters and they are no fun to drive. the tires are huge and wide. because they're wide, they'll follow every damn groove in the road as well and any ruts. you would think because of the wide tire, the ride would be nice and soft with easy driving, the reality is quite the opposite..
