Good questions. My understanding is that AAM rates my rear axle at 10,800#s. GM then rates the axle down to 6084#s which is the tire rating total for the two stock tires on the rear axle.
this /\
and then this below...
I know that here in TX the state codes say that a load on an axle can not exceed the combined tire rating for the tires on said axle. I have 265E's which have a rating a little of over 3400#s each. That would limit me to a little over 6800#'s. I am currently under that by about 1300#'s.
I believe that the above two quotes brings us to the Tires...regardless what your axle is rated at...that information is meaningless unless you have tires rate
ABOVE that rating...which aint gonna happen.
Logic dictates that if you load up an axles to say 8500 lbs and then blow a tire because you exceeded the tire manufacturers rating - and cause an accident - YOU are liable...regardless of the axle rating
My truck has 17" 265/70R17 BFG Rugged Trails
As per= jmramiiler states both him and I are maxed out at ~6800 lbs on the axle/tires. This at the maximaum rated pressure of said tires which is 80 lbs..I do believe that figure will drop as the tire pressure drops.
I live in Calgary Alberta. There is little enforcement of anything like this in our Province..and to be fair there is little anywhere in Canada...but as Noted previously, if your rig looks unsafe, thats when you are going to get pulled over...and from what I have heard from speaking with others, they will in fact go with the door sticker information if you are told to go a scale.
For me, I am likely OK as far as looking good, I added a set of Roadmaster Active suspension springs and it improved the stance of the truck when hooked up. But I am also pretty certain that although my rear axle weight is under the tire rating, I am over my total truck GVWR..by about 350lbs - All to do with pin weight.
I'm Ok with that..its just the beer.!
