A Question About Truck Scales

Some states you can go more on the steers. Just not over on your gross.
That or they were busy doing something else

 

Yes, steers are not limited to 12k. Steers are limited by the axle rating, and the tire rating. It is just convenient to say 12k, 34k, and 34k... which equals 80k. Many steers on OTR trucks are rated for 6,250 lbs each, or 12,500 on the steer axle.

 

In my experience, DOT generally winks at overweight steers unless they're egregiously over (1k+). You were probably walking a fine line at 900 pounds.

It's generally not worth the hassle of going out to check a truck that may have a steer axle and tires that are rated for heavier weights.

 

12k isn't the max on steers. oregeon will allow 12.3 before they pop you. i run around at 12.5 and make sure i'm not full tank before hitting any oregon scale.

 

This is true, but you have to be mindful of both the tire AND axle rating before ignoring the 12k guideline.

For example, my steer tires are rated at 6250, but the axle is rated at 12,000 lbs. So if I run over 12k, I'm illegal regardless of what the side of the tire says.

(I know you said as much, but spelling it out for those not as familiar with the regulations considering the forum we're in)

 

Wow, I'm surprised nobody got the answer correct so far. The answer is you are allowed 20,000 on the steer and 34,000 on drives and trailer, but the max cannot exceed 80,000. This is because the newer trucks with set back axles are almost always over 12,000. That's why the scale didn't say anything to you.
You need to keep in mind that your axle is not factory rated for 20,000 though, except if you have a heavy haul truck designed for it.
If you have a Rand McNally Motor Carriers Road Atlas, check the weights section and you will see that I am right.

Look at old Volvo 770s. They are always over twelve, up to 14k. Go off axle and tire ratings.

 

He's right, first few pages (before the restricted routing and low bridge location page areas) has a huge directory of state-by-state information.
Also, check the rated weight for your axle (listed in owners manual) and make sure to thoroughly inspect those steers before running them heavy.

 

Arkansas is the only state where 12,000 max on steers all others at least 12,500
