Today test drove 2013 DRW high output with aisen

[AH64ID]

Please answer my question what is the gvw of a 2011 drw? The difference now is that 10 ply 17"s 8-9 years ago were rated the same as they are now but we have raised the wheel capacities 400+#s and gvws are streaching the very top limit of the tires. We might be asking for troubles.

IIRC a 2011 is 12,300.

Look at a SRW from 2003 with 17's and a 2013 SRW with 17's, they both have axle limits at 97% of the tires. The new 6,000 lb front axle is also at 97%. This is not something new, I think you are making an issue where there isn't one.

Actually there are 2 versions one zf built and 1 corporate version. Different parts same basic design by not quite the same

Yes, thats the way I understand it. The ZF is an 8spd used in the Grand Cherokee and Ram 1500. It will include the Hemi and diesel power. The Corporate version is a 9spd used in the Cherokee with only the 4 cylinder or small v/6.

Does a 2013 SRW have a 6k front end? Wheels in 2003 were rated at 2600# and that changed when Dodge went to 5200# front axle. Tires stayed the same. DRW now has 6k front axle and I don't know the wheel cap. Have not seen that yet. Were are talking dually here not a 2500 with 18" tires.

ith 3. 42 Axle Ratio Axle Ratio You Can Tow 9500 lbs

Gross Vehicle Weight Rating (GVWR) = 12200 lbs

Payload = 4849 lbs

Curb Weight = 7351 lbs

Curb Weight Front/Rear = 4426 lbs/4426 lbs

GAWR Front/Rear = 5200 lbs/9350 lbs

Gross Combination Weight Rating (GCWR) = 17000 lbs





Cummins98 figures show 13,960#s on truck with 12,200 gvw. and overall gross while towing with 3. 42s at 28k. I gross 27k many times with my RV with no issues with 19. 5s.

We are not talking about a 2011 we are talking about a 2013 with 14kgvw.

You are talking about 14K and 17" tires so I gave you an example.

My weight rating for my truck is 12,300#

I am under the front and rear axle ratings by quite a bit but over the combined. Silly numbers!

Truck handles the 14K load easily.

You brought up a conversation about 17" tires not being able to handle a 14K GVW, you were provided an example and are now picking it apart. How about just looking at the example for what it is, 14K GVW on 17's.

No one mentioned 18" tires. Simply pointing out that GAWR and Tires have been at 97% for the last 10 years, it's noting NEW for the 6K front end. It's IRRELEVANT if it's SRW or DRW, it's a tire loading comparison. You are worried the tires are rated too close to the GAWR, it's a ratio Dodge/Ram has used for a long time.

The 6K front end is GREAT, maybe they will last longer, but it's going to be difficult to load up to 6K on the front end. A snow plow will do it, but how many of those will be on a 14K GVWR DRW? But in terms of longevity at least the axle wont be above 90% of it's rating on an empty pickup.

Had the New 2013 prep and took for test drive, it has a terrible vibration at 67-74 MPH, We are working on it today to find the cause... . My guess another driveline Vib,We will drop both front and rear DLs today. We have another 2013 3500 on the lot We will test drive today to see if it has the same Vib. Don't expect to use the factory Gooseneck/5th anytime soon the Ball and SC are NOT available. RAM you have made a big mess out of this, I'm sure Ram will blow smoke up the weekend warriors rear but someone who knows his stuff is goonna be pisssssoffffffff Pic's here https://www.turbodieselregister.com...687-4Th-Gen-impressions&p=2348959#post2348959 Post 97.



I like the changes Ram made,its a big improvement over My 03,05,12. OEM to OEM.

Don't put words in my mouth. I never said 17" were not able I said they were near their limit.

Great photos, now that I see what the new capless fuel filler looks like I see the concern of dirt and whatever getting in there, if I owned one I would be looking for a rubber plug that would stick in that hole, sort of like the ones they have for wine bottles, just larger

You are not concerned about the 17"s ability to support weight at 97% of their load rating? Could have fooled me with the number of threads you bash 17" wheels in.

I am not trying to put words in your mouth, just the impression I have received from your posts in multiple threads.

You are fooling yourself. For many years ( ten maybe) truck makers have been using 17" rated at 3000 +- 200#s. That is 6000 +- 200-400#s. With 5k axles and 2600# wheels that was a large margin. If you look at my photo below the 17" tire is sitting on a DOT style scale. When duallys roll down the hwy. on a crowned road or in and out of semi ruts in the interstate the inside and outside tires at different times carry much more that 3200#s. In our testing we found that individual tires load increased to 4500#s. Now that was in 06 we did the testing. That was with 5200# front axles and duals on the rear and rims rated at 2600#s. Then the front axle ratings went up to I think 5500#s and wooo the rim ratings went up also but the tires stayed the same. At that time there was a comfortable margin. Now we are at 6k front axles. Next time you go look at a 2013 single or dual with steel wheels I'll bet the rims are rated at 3k or a little higher. And guess what (same ole 17" tires). Wheel and rim loadings have increased 20%. Tires 0%. The other big difference is that cab designs have changed in 10 years. We went from 2 door to crew cabs. That in it self placed several 100 more pounds on the front axle. But same ole tires capacities. I can't wait till someone posts photos of a new 2013 quad cab with no extra springs or air bags carrying a fully loaded RV or goose neck and the truck is carrying the max on the rear axle that the book allows at 14K. You will see one more squatting buck butt busting truck. Next thing we will hear is "how about air bags"?. The 2013 dually I looked at did have a good looking set of rear springs. Please tell where you are coming up with 97%?

97% is simple math. 3085 (235/80/17) * 2 / 6000 = 97% of tire capacity at FAWR.

A fully loaded DRW at 9,350 lbs puts the tires at 75% of capacity.

Tire ratings are cold pressure and static measurements, meaning that the manufacturer accounts for increase in weight from turning, crown of the road, bumps, winds, etc.

So if you are afraid of not having a comfortable margin on tires how heavily can you load a 14K GVWR truck? 9K, 10K? The 75% margin on the rear axle of DRW seems to make you uncomfortable, so would 75% of 14K be okay? That's 10,500 lbs. Does the same apply to a tow rating? Your OEM tow rating is 15,350, so you do limit yourself to less than 11,500 lbs?? You don't, do you?

Not all 17" OEM wheels are rated at 2600lbs, the SRW wheel is rated to at least 3100 lbs (it's not on the wheel).

How do you figure wheel and load ratings have increased by 20%? The RAWR on a 03-12 is 6,200lbs with 6390lbs worth of tires, 97% again (and has been since MY2003).

My friend's '10 Crew Cab 8' bed truck actually has less weight on the front axle than my '05 with the quad cab. Not to mention when the 17" OEM tire was introduced Dodge had a 4 door truck.

Time to recheck your facts...

 

[Cummins12V98]

I am at 13,940 combined weight on my 6 tires.

front axle tire rating is 6,160 my actual is 5,180 I have 990# left!

rear axle tire rating 11,344 actual 8,780 I have 2,564# left!

I really don't see the problem with the 17's !
