I have a set of 35x12.50x17" Goodyear Wrangler MTR's and looking for a set of black rims to put these on.
I have a 1997 Ram 2500 2" susp lift and 3" body lift. I have just installed a set of Lund Elite series RX202S fender flares. I would like to get a rim that will get these tires to get outward a bit to have a good stance with these flares. ANy suggestions or preferences would be great. Im completely clueless of offsets and all the jibber jabber that goes with spacing and stuff.

 

also what is the pro's and cons of steel vs. aluminum

Thanks...]

Offset is irrelevant. You are concerned with backspacing. Your current wheels (assuming stock) have 4.5 inches of backspacing. (or, thereabouts) That is the distance measure from the tire bead, to the mounting face where the wheel gets bolted to the hub. Wider wheels with the same backspacing will stick out further than stock. You want your wheel to be in inch or two narrower than your tire.... So 9-10 inch wide would be good, 11 may be pushing it..... (might rub on the fender/bumper when the tire is stuffed in there.... (suspension compressed some)) Stick with the same, or no more than 1" less backspacing. That will give you wheels that your tires want to stay on, and a bit wider stance.

As for steel vs. aluminum..... aluminum is lighter, but, on a truck with solid axles, the little bit of difference just isn't going to matter. Not like your truck is a back street weapon in any event..... and you shouldn't try and drive it that way either. (though, I do sometimes forget that my truck is NOT my Firebird........)

So, find wheels you like, with the dimensions you want, and don't really worry about what it is made of.

 

just get some pro comp steelys

 

So smaller # of backspacing pushes tire outwards? So if im looking at wheels that are 4.79 backspacing and are 17x9" im gaining roughly 3/4" provided stock rims are 8"

And what is offset if it has nothing to do with pushing out the stance? Im clueless with this so bear with me

 

Wheel offset explained:

Pretty much.

Offset is a different way of measuring backspacing, just a bit less direct. (and can be confusing, that's why I prefer just using backspacing.) It is the distance from the mounting surface of the wheel (where it bolts to the hub) and the wheel centerline. You can determine backspacing if you know rim width, and offset..... I just prefer to use backspacing directly. I think it gives a better picture of what you really want to know.

Rim width plus offset equals backspacing. If that makes any sense.

 

Kinda makes sense. Some rims you look at give backspace and not offset and others are opposite. Right now im looking at 17"x9 with -6mm offset??

 

That's about 4.25 backspacing. Should be OK.

 

17x9 -6 would be 4.75" bs, I'd look for some closer to 4-4.25 Here's a chart where you can figure bs from offset and wheel width
