How will reinforcing the springs add load carrying capacity? How could it not. Whenever a mechanical part is strengthened it gains better ability to do it's job. Swapping heavier duty springs, axles, tires, wheels, etc. onto a truck will in fact increase the ability of the truck to carry weight. It's just a machine and conforms to the laws of physics.
No, it won't change the sticker on the door. Lets say I have a 3500 truck with an 11,000 pound GVWR. My driver's door gets dented and I go to the junk yard and get a door from a 1500 truck to replace it. Now the door sticker's GVWR number is 7,500. I'm I know restricted to a GVWR of 7,500 with my 3500 truck because of what the sticker says?

Reinforcing the springs will not add capacity because the springs aren't the only thing needed to support the load. Putting fancy springs on your truck does not increase the tire rating, make the frame stronger, or make it stop any faster.

The sticker on the door is the manufacturer's rated capacity for that truck. And no, changing the door, changing the sticker, or removing the sticker won't change the facts.

Your state might have lax laws but not all do.

The tire rating is stamped right on the side of the tire. The tire manufacturer publishes a load inflation table. It will tell you how many PSI the tire needs to carry a certain weight. Get your axle weights using a truck scale, consult the chart, inflate accordingly.

az dry heat. My door sticker says ~~GAWR FRT (3500lb) with265/70r16 32psi cold ~~ Rear (3760lb) 33psi.

Door sticker never saw my E rated tires

Re-arching springs brings spring pack back to OEM state
Adding an extra leaf increases spring pack load capacity

Neither will increase the GVWR which is a MFG rating for CLASS of truck


Max Load Rating at MAX PSI is STAMPED on sidewall of tires

Go with your feelings, it won't increase what your truck is designed to carry. That is all, no other answer but you knew that.

The only tire ratings is the maximum weight that tire can carry at a specified PSI. Normally an E rated truck tire at 80 psi is rated to carry 3042 pounds maximum. What does your door sticker say? Mine says 70 psi front and 65 psi rear (dually). Those tire pressures, in my truck's case, correspond to the air pressure needed for a maximum load. No use putting in more air if it isn't needed.

Where do I find Tire ratings?? BF Goodrich ~ All Terrain lt625/70r16 "E" max psi 80 Apr/2018 Question on that Tire shop says never run more than 40 ~~ Mechanic friend says 75 another says 50. I will be getting truch weighed all 4 corners soon.

~~GAWR FRT (3500lb) with265/70r16 32psi cold ~~ Rear (3760lb) 33psi.

Does any of that help

Thanks for your time & insight

Please, show this retired cop any law that says it's illegal to "run over the tire rating" as it pertains to us RVers.

May level the truck but won’t increase payload.

Its not that it allows more to be carried but let's it carry the weight better
