Explanation about weight needed

You are incorrect concerning the steers, and the drive weights differ in some states, and I chose to stop there since the bold text gives me a headache.....

 

To make it simple most tractors have 12,000 lb front axles and 40,000 lb rear axles and that is plenty for the regular legal loads that you pull every day of a maximum 80,000 lb.

Over 80,000 lb you have to have permits to be overweight and that's not considered to be just a regular load. The regular reefer loads that you will pull are not over 80,000 pounds.

When you see heavier axles like 44000 lb or 46000 lb rears, and you see 16000 lb front axles and that type of thing, that usually is either for a dump truck or for a truck that regularly pulls overweight loads, beyond the regular 80,000 lb legal loads.

 

Most newer set of 40s will be fine for ~75% of all trucking, especially general freight, I run 100.000+ on a set of 40k-404s and a 12 front, might want to go to a 13,2 or 14,6 if you have a curb sniffer though as you have a better chance of actually putting weight up front, only real difference between that and a 46k is the actual housings, a frame slipper by the 5th wheel, and in some cases axle sizes and suspension, (unless you start getting into the really big rears ~52k+)

And of course I nor anyone on ttr would advocate running overweight, but even if you find yourself “close” on a reefer load that may pay by 100 weight/pallet, you should still be fine with 40s

 

I never have more then 11,020 on my w900, whether I am empty or have 80,000
IN the trailer

your trailer will still get 34-40k on it.

Most 40,000 pound rears have 3/8” housings instead of 1/2” and no frame slipper along with some other differences, so they are lighter to begin with

 

Respect the staff, sir. Please.
