As Marty says, Washington has a formula of tare weight times 1.5 and then rounded up to the nearest even K. So my old 2001.5 with 8800 GVWR was licensed to 12K. The new truck with 11,700 GVWR is licensed to the same 12K, I could have paid a bit more and licensed it at 14K. I was at 11,020 with a light load in the new truck and trailer on my first trip to the Cat Scale. So if we get a larger trailer We may or may not have to do that, as the rear tires may limit it from going over 12k anyway. Chris
Chris,
Rear tires will not limit you. We get 600 lbs per inch width of tire. Does not matter what the tires themselves say on the sidewall. You probably have the max axel wt of 20K available on the rear per the state laws. At least my 05 with 215-16's had the 20K available. Yeah they were rated to around 10-11K lbs total.......Add in 245's to the front, I could technically run down the road to 32K gvw with a 3500 truck!
You would probably run into problems with braking frankly. Not sure stock brakes can stop a 32K gvw rig in 25' at 20 mph or some such field test that would be done. Stop in that time, distance, you are good to go. You do not, you have a failed braking system, and are red tagged at the side of the road until brakes are fixed, or a flatbed hauls you to a mechanic.
One needs to know the local laws to see if they will or will not be legal. Wa st is pretty liberal as to how much we can or can not carry etc. as to not lose federal funding per Federal bridge laws. There are other laws as I have shown, ie braking that will get ALL of us in trouble before the weight laws go into effect. I've even been pulled over higher than my paid for license in MDT, but was given a 10 day up my license by 2000 lbs, as I was under the FBL limits! Even if I was over, it is not a moving violation, nor a jail time violation! The FBL's are there to protect the road bed only! from overloads damaging the road bed!
