I'm looking for any Ram 2500 / 3500 OEM wheels with an offset between 25mm and 43mm. I've been using this website: https://www.wheel-size.com/size/dodg...el=111:1,113:3 which seems to suggest a lot of possibilities, but I can't seem to find many of the suggested OEM sizes they show. They are showing 18" and 20" sizes for 3rd Gen trucks, but I'm not sure that was ever available.

I am running a Nissan NV van which has an 8x6.5" bolt pattern and 121mm center bore, so I'm trying to find all my options of OEM Dodge wheels that may fit.

Ideally, I'm picturing an 18x8 with an offset between 30 and 43mm, or a 17x8 with 31mm or lower, but I'm literally looking for anything to figure out my options. I'm not sure I'll be able to find something to crossover, but figured I'd ask.

Thank you for your help, Chris

 

20" rims we're a common standard on 3rd gen 1500 not sure on the 2500/3500

 

I think that's where the problem is when I'm looking. I'm getting mix and match data for the 2500 that includes wheel sizes from the 1500.

As far as I can tell, 3rd gen 2500/3500 SRW 17" rims are on a 43mm offset (With a possibility of the PowerWagon having an offset around 45mm). When 18" and 20" rims were introduced (After the brand change?), they're offset was 54mm+.

I'm surprised that with the 3rd gen trucks having 43mm offset and the newest Ram trucks having offsets of 54mm+... the aftermarket rims available are still 20mm or less. I would imagine more 25mm and 30mm options coming to market, but even the 25mm options I can find tend to be discontinued.

 

I can't say anything in the subject in running aftermarket wheels with almost zero offset

 

Offset is a meaningless bit of info, without knowing how WIDE the wheels are. You can have a selection of wheels with the exact same offset, but, different widths. What that spec changes is BACKSPACING. THAT is the spec you are really interested in.

 

I used to focus on back spacing, but now I focus on offset. Backspacing is generally a measurement that only informs us about wheel fitment. Offset generally informs us about wheel fitment, suspension loading, steering geometry, tire position, etc. Over time I've found it more useful.

I understand your perspective, but I disagree strongly that the offset is meaningless without knowing how wide the wheels are. For example: I know without any consideration for any other measurements, that a wheel with an offset less than 0mm or greater than 50mm will not fit regardless of width or any other dimension in my application. As a result, it is not necessarily meaningless on its own, it is just my first filter right now since I've had a hard time finding the sizes I'm looking for. At the same time, I know a wheel smaller than 17" will not fit my brakes. So, without regard for any other dimension, I can ignore anything less than 17".

Once I find something in the right range, then I can consider the other dimensions (of course, all of which need to be considered).

 

Erm...... Yeah. You can have your 40mm of offset, and applied to an 8 inch wheel, it will fit, applied to a 9 or 10 inch wide wheel, it *might* fit, applied to a 12" wide wheel, it WON'T fit. Backspacing, and width are what you need to know to determine fitment. Offset is just calculated from those two. (or the other way around, its just math.)

I usually decide what tire I want to run, see what the manufacturers recommendation for rim width is, and go shopping from there, choosing wheels with backspacing that will keep the geometry as close to stock as possible, so things like steering geometry, and suspension loading don't get weird.
