We haul heavy loads on 6 axles. Three axled tractor and 3 axled trailer. Is a 40,000lb rear end and 12,000lb front end axles enough. We usually gross around 93,000lbs.
Thanks in advance.

There are two 40,000 rears..a regular one or a heavier one.. it has bigger axles...but at 93000 lbs you should be fine..it pulling weight.. not more weight on the rears..ive seen 129000 pulled with the regular axles ...

Thanks for your input. What is the GCW fo your tractor? We have one that is 97,000lbs and another that is 80,000lbs. Not sure what happens to make one be able to gross more than the other.
We have not had any rear end problems either over the past several years pulling heavy.

My tractor is stamped at 52k and registered for gross 80k . I run permits which allow me 95k only in my state. as far as your one truck being heavier, does it have maybe an 18k front axle and maybe 46k rears?

I've run over 600 hp with sqhd rears. You can get away with a lot if the driver understands how to care for his ride.
