What exactly is the steer axle weight limit?

Cops are rarely very knowledgeable about DOT law. That's why there's so much wrong "interpretation". You ask three cops a question about it, and you'll get three different answers.

That being said, I called the Wyoming/Colorado port of entry with a question about ten years ago. It was similar to yours. They said they only care about three things: Axles can't exceed 20k, you can't exceed your tire rating, and you can't exceed your registered weight. I said "this is a pickup we're talking about here. What about brakes??" They said they didn't care about any of that. Just those three things.

There's a lot of truckers on this site that know the law through and through, and even they disagree on interpretation some times. The laws are too convoluted.

 

When did Ford make tandem F350's.

Duals yes. Never seen a tandem though. And I don't think they make steers rated as heavy as semis.

 

just a point
6,175 × 2 = 12,350 not 12,300

 

I know, I know, don't be a...

 

Dodge built a tandem pickup prototype based on the 2nd gen Ram bodystyle.

 

Basically the same answer I got up here, except we don't register for gross weight even on commercial pickups. Our max axle weights are determined by tire width on singles. You can't exceed 600lbs per inch of tire. That gives us 13,200# on a 11R22.5. It also has a max of 20,000# regardless of width. Then they go by tire capacity. They are absolutely not concerned with any vehicle GVW tags. In fact, my Ram has nothing on the tag other than do not exceed 4,300# of cargo with no mention of GVW, GVWR, or GCVWR. My brand new Kenworth T-880 has only the GVW on the tag, with no mention of front or rear axle weight limits, or GCVWR.

 

They don't put axle weights on the labels anymore?
