Load Range D Tires on Ram 2500

[Bennutts]

I do appreciate all the info but I’m probably more confused now than before. I did air down this morning to 50psi all the way around and it seemed a little better actually. I’m not sure how much vibration I should have if any at all.

Also gonna have to research the chalk test.

So here's the difference in weight rating between the Duratracs and the Cooper Maxx

 

[Bennutts]

After doing a lot of reading this morning I've seen that alot of guys are only running between 50-60psi unloaded. I rarely do any towing. I'm thinking of running the rears at 50 and the fronts at 60 and just dealing with the tpms light, unless I can change it with alfaobd once it donwloaded.

 

[hoe...]

There's no problem with running 50 to 60 psi unloaded. The problem is if you then load it up and don't pump the tyres back up to 80.

Thats why the dealers can't lower the tpms threshold, otherwise somebody would have an accident then sue the dealer because they weren't warned by the truck that the pressures were too low.....

These days nobody wants to take responsibility for their mistakes, its always someone else's fault so let's sue them....

When I’m daily driving my truck. I run 45front 40 rear. When loaded with my smaller trailer. I’ll run 45 front and 60 rear, if I’m pulling my bigger trailer. Then depending what’s inside it weight wise 45 front and 65-70 rear typically. I have been a bad boy and had 5500lbs in the back of my truck and left the rear tires at 50lbs. I took it super easy coming home (had to go 20 miles after picking up an unexpected load of stone from Lowes)

I guess at this point I need to decide if I need to get and E tire or not. I really don't tow much and if i do it's not heavy.

Due to the weight of the overall truck you would be better going with the E.

Interesting,

If I chalk test I need 65 at the front with 285/75/18 Toyo MTs. And these are stiff tires to. Over 4000 pound rating.

My duratracs I could visually see the outside edge of the tire was off the ground at 60lbs, started touching around 50, and was happy at 45, my transjunk at’s were 50 front and 45 rear

Im Sure a lot of it must depend on the specific tire and how it is made. And how well it creates a nice footprint.

Oh yeah for sure, no two tires are the same really. Between construction, plys, and design all play into it. When I had my Tacoma (which from tacomaworld is where I learned this) it was actually scary how low the tires had to be to run with the tire even on the surface in the bfgoodrich rugged trails

I understand completely my old ranger I was running 32/11.50/15’s. BFGKM2’s. I was basically at 28 pounds in the front and 24 rear.

The stock duratracs on my power wagon did not look overinflated at all with max psi of 65. I ran them at 60psi in the front and 48 in the back and they had a nice size bulge. These trucks are just flat out heavy.

do a quick search .there is a couple of ways to do it,i rented a tool from a member 4x4x4 guy I believe his name is.50$ for a one time rental .works great ,I run my nittos at around 50 p.s.i unless I am towing

I think my biggest issue now is going to be if I do end up pulling something am I gonna be ok to do it with these D rated tires. I don't see myself in a situation where I'd be pulling anything very heavy in the near future.

If you want to get an idea. Look up the specs on a power wagon, more then likely unless your trailer is going to have a lot of tongue weight you’ll be fine, even with my 3500, very rarely I do I have over 1000-1500 lbs of tongue weight from my trailer
