2020 3500 Rear axel details

[Jim-Florida]

Anyone know the specifics of the 2020 3500 rear axel? I’m trying to figure out if I upgrade to a heavier rated tire would I be able to increase my capacity. I realize there are many engineering factors that go into determining the trucks capacity but I’m beginning to believe that while they publish 7k lbs for the rear, they can technically carry more. My current tires are only rated at 3690lbs and I’m being told that I could safely exceed my capacity (on the order of a few hundred pounds) by increasing weight loading of tires.

Two tires rated at 3690lbs load capacity are already higher than your rated axle capacity of 7k. As far as getting higher load rated tires....NO. You won't increase your capacity. This has been brought up in many threads. One person here keeps telling people that you increase your load carrying capacity by buying higher load rated tires which is false.

Welcome to the Forum! What brings this up, are you shopping truck campers, or is it a huge fiver? Let me guess, the people giving you this advice are wanting to sell you the same thing that’s going to overload your truck...

Some people go to 19.5’s to get more tire capacity. There’s a company that specializes in sourcing tires and wheels (Rickson).

I don’t want to come across as a Monday morning quarterback, but why not buy as much truck as you need to begin with?

PS Cummings is a town in Georgia. Until you correct your truck description you’ll catch a measure of flak for that. I’d blame autocorrect myself.

This will not answer OP question and I most likely should just keep my mouth shut. Buuuuut, I cannot help myself. I ran a truck camper on a 3500 series truck for may years. I built the truck almost exclusively to carry the camper. Even went 2 Wheel drive to save weight. I was always within Specs. Probably 8 out of ten campers I run into were overloaded. Often grossly.
The rationalization of doing it was nothing short of amazing. Ranged from " well, they test the frames at stresses WAY over what the truck is rated for" to "I put heavy duty shocks and helper springs on" to "I installed Timbrens" to " I put higher load carrying tires on" etc, etc.
Then they would grossly overload the camper beyond what it was rated for. It went on and on.
Often would be towing a vehicle or trailer with the camper in the bed as well.
If that is what you are trying to figure out, just get a truck that is appropriate for the service
you will expect from it.

Climbing ito my flame suit.

Sounds like you need a 5500.

Technically yes. Not to say that it’s safe or recommended. But yes if you have a stronger tire you’ll carry more weight. Just may break the truck before the tire.
