Registration Weight Rating Increase?

Many(most) states require the truck to registered to above 80k and above the requested weight or to the state maximum before a O/W permit is issued.
This is another way to add to the state coffers. You pay extra rates to register and your fuel tax or mileage rate is higher. If you register to the max everywhere your taxes increase by about 5%.
Your initial cost can be reduced by only "bumping" your registration at home and surrounding states and any states you regularly run in. Then you can "bump" any new states when required, it can be done online or over the phone usually within 2 working days.

 

I've got Idaho at 130,000#. Can't remember if that was the max or if it was just where I called it quits.

 

Some states will let you run more than the 80,000 pounds with a specific tag type
