Hey guys.

I have been doing some reading, and I think I have a slight problem.

I notice that my 2005 1 ton dodge (crew cab longbox single wheel) says max GVWR is 9900lbs. This is with the stock pile of crap BFG Rugged Trail tires. But they are E rated.

Does this mean if I have a toolbox in the back (big heavy one), with me and all my personal gear, the max that truck should tip at the scales is 9900lbs?

I contract for a few different outfits, and I haul their tools back and fourth all the time. I have noticed that some boxes are 3000lbs+. I KNOW that once the truck tipped 11,000lbs at the scales because I weighed it myself.

I now have a 6" lift and D rated 37" tires. I am assuming my truck has a lowered GVWR now because of this. I was also told by some that the bigger tire in the "D" category is rated higher then the smaller tires in the "E". Is this true?

Also, if I were to haul a trailer behind me (with the D rated 37s), how heavy of a trailer can I tow with my factory hitch?

I need to get to the bottom of this and start either checking each box, or, buy a nice car haul trailer and use it for work.

Help me out guys, I am new to hauling/towing bussiness.

Thanks.

 

The 9900 lbs GVWR is your limit regardless of any modifications you make. You can make the truck handle more weight, but it won't be legal.

 

That is right technically, with your truck alone (no trailer), you can't go more than 9900#. That is US law, no clue about Canada.

With a trailer, you get the GVW of the truck + the GVW of the trailer, provided you never go over any axle/tire limits.

Your tires will say on the sidewall what they are rated to @ what PSI. Some D's can have more of a load range than the stock E's, but they are at a lower pressure which to me does not mean it's necessarily safer. E.g. I'd rather have a 3415# pounds load @ 80 PSI on stock tires than 3415# pounds @ 60 PSI on load Range D's.

Towing with 37's in general is not a good idea in my opinion, same with the lift.

In theory, with stock tires, you are fine to go over the GVW as long as you don't go over the tire limit. The GVW of a 3500 dually is 12,000 (??) and the brakes are the same as your truck, so is the suspension. So if the rear end of the truck weighs 3000# from the factory, you would be ok with another 3000# on there. That is technically, NOT legally and again, with the stock tires at full 80 PSI.

 

Thanks guys, this makes sence.


Honestly, I got the lift because some of the locations I go to are brutal, they have huge ruts and bad mud. Having said that, I would not have to haul my trailer through that, just park it on the edge of the location. So far the lift/tires are doing what I got them to do.

I agree on the towing and the lift, but it is what I have, and will have to make do. If I hauled a car on my trailer, or an occasional 3000lb box, i would hope it would not be a big problem.

DOT in Canada also has the same rules....anything over 9900lbs is not legal. I was just worried that my new tires would make that even less, but went and checked and they are in fact rated for a higher load then the stockers.

Thanks.

Also, the GVWR on my Dodge is 9900lbs, but on my co-workers Powerstroke its 11,4000lbs. Are the Fords really rated that much higher, and/or are they heavier empty then our dodges?

 

This has been discussed before here . A lot of GVW ratings are to impress the government for EPA ratings and staying under 10,000 gvw so drivers don't require logboks or under 26,000 so you don't need a CDL ( like the International pickups rated at 25,999 ) Many hotshotters are legally running duallies registered over 30,000lbs.

 

In canada, and specifically in alberta the gvwr dont mean anything, except too take up space on the sticker. The axle weights, and tire ratings(more important) are whats important. But first you need an idiot cop or transport canada guy too expect you too weigh in....THAT WONT HAPPEN!!! And with 16" rims are legally allowed too tow 42,000 pounds!

 

Well if you need the lift then perfect -- at least you are using it unlike most lifted trucks I see! It sounds like some fun driving What are the 37's rated to, out of curiosity? And at what PSI?

I didn't mean to say that towing ANYTHING with 37's is a bad idea... just towing real heavy (thinking 10,000+ trailers).

I think Ford just does the GVW thing for the numbers so they can brag. What is the GVW on a dually Ford? I think 11400 is on the single rear wheel right?

The specs for Dodge is 9000 (new 2500's), 9900 (srw 2500's) and I think 12000 on the duallys... or is still 11500? I've even seen 12,200 somewhere I thought...

 

I tow a 12K lb. fiver on 35" D Range BFGs all the time. No problems. I am way below the max rating of the tires and rear axle of the truck. I am not really lifted, just a 2" kit to bring the front up level and allow bigger tires. Some areas we go require a little extra ground clearance. My setup is a lot safer than some stock trucks I see going down the road that just aren't setup right.

Get the towing setup right so everything is level and the trailer is not sitting nose high. You may need an awfully long drop on your ball mount to get the trailer height where it should be. Hard to find those unless they are rated very low. Get the setup right and you will be just as safe as anyone else.

 

12,200 is correct , just checked tag on my 04 dually . Ford inflates their #'s so bad it's silly ! Hauled a Case skid steer for my buddy with many large pcs of broken asphalt and truck didn't even hit overloads ,pulled great . He comes to pick it up with his 2000 F-350 and suspension was squatting so bad the breakaway switch on trailer was engaging !! Should have heard that 7.3 powerjoke straining to get moving ........ PRICELESS !!! Another Ford buddy had a leaf spring break on his drivers side rear and he NEVER hauls more than 8000 lbs . I guarantee these Dodge's will haul more weight and live to tell about it all day long with no prob .

 

Exactly, I towed about a 15000lb trailer tag along and I had roughly 2000lbs-+ tongue weight and the overload springs wernt even engaged yet.

 

There has to be something with those Ford springs. My friend's cousin broke both of his leaves, before a pull last year a guy noticed he broke one of his, and when I worked at Tires Plus, some guy came in and gave me his leaf packs because, sure enough, one had a broken spring. It's all on the newer Super Duty's, too.
