What is the load rate for wheels on a 2500?

[31b]

I just recently bought my first diesel and just subscribed to TDR. This has been a great source of info.



The rear GAWR on my 2007 2500 is 6010lbs. Shouldn't the minimum load rate be 3000lbs for each wheel? The local dealership did not know what the OE wheels were rated. I just bought a set of after market wheels and they are marked 2800lbs max and 60 psi max. Was I sold the wrong set of wheels or is 2800lbs no problem?



I don't want to name the wheel manufacturer because I am trying to resolve this question with them first. Any opinions are welcome.



Thanks in advance.

With OE tires/wheels the limiting factor is typically the tires. Especially on a 2500. 2800lbs at 60psi sounds like oversized "D" rated tires. I guess it depends on your truck use. For lots of strength with a 2500 you'd be looking at 19. 5" tires.

Pull a wheel off and see what is stamped on the backside.

If you dismount the tire and wheel you'll normally find the wheel's rating stamped on the inside.

The factory wheel on a SRW Ram would normally have a maximum inflation pressure of 80 psi and a maximum weight capacity of approximately 3500 lbs. The OEM tire with a max weight capacity of between 3000 and 3100 lbs. would be the limiting factor.

Wheels rated at 2500 lbs. may look good but are clearly not as strong as OEM wheels and will limit the work you can do with your truck.

If those are D rated tires, chances are they're pretty squishy sidewalls.



Handling will be very poor.



Quick lane changes, especially if you've much of any load, can be near disaster trying to hold a stable line.



If at all possible get the dealer to take them back. You've been sold a product with rating lower than required for safe vehicle operation.

All, thanks for the replies.



Looking at the replies I may have been unclear, the rims are stamped 2800lbs max and 60 psi max. The tires are Toyo 285/75/R17 open country AT's and are E rated. So far the tires are great.



I looked at the factory 17X8 aluminium OE rims and there is no weight rating or PSI markings on them.



So, am I correct in thinking that if my rear GAWR is 6010 lbs the rims need to have a minimum weight rating of 3000lbs? Was I sold the wrong aftermrket rim because it is stamped 2800lbs max and 60 PSI max or is it fine?



Thanks in advance.

If the max is 60psi but, the tires are max rated at 80psi you have a mismatch. At 60psi, your E rated tires will probably hold 2,550lbs versus 3,400lbs (or so) they're rated at.

31b, Do you still have the OEM aluminum wheels?



If you do, are they for sale?

I still have the OEM rims, but, if it turns out that the aftermarket rims are the wrong weight rating then I'm going to put the OEH rims back on to my truck. I appreciate the offer though.

There is a very good artical in one of the latest diesel mags on the market today. This artical outlines what the weight rating means and how tires are labled for load capacity. The Mag name is "Diesel World" Decemeber issue. This may help you with your issue on the rims and tires. I do not know if you have a new 2500 Ram or not but you may have the TPMS on your truck. If you do then I believe you will need to transfer the monitors to the wheels. This will measure the air pressure in the tire and you will need to run at least 60 PSI in the rear (under light load) or 70 psi. That is why the new 2008 and aboved will have E rated tires on them to handle the higher capacity.

All: Appreciate the replies.



JimW, I believe that my truck did come w/ the TPMS.



As far as weight rating goes, it looks like the OEM wheel must equal the weight rating of the OEM tire that came with it. To the best of my memory the original tires that came on the truck were Micheline's rated at 3195lbs at 80PSI. So, the OEM wheels are probably rated at 3200lbs.



So, as the aftermarket wheels are rated at 2800lbs at 60PSI they are short 400lbs. The bottom line is at the "end of the day," I got sold the wrong set of wheels. I'll see what the manufacturer has to say.
