I'm not very good at selecting aftermarket rims. Just not sure about the back spacing on the Rams. Here is what I'm Look at ProComp:18X9" (wide) 5X5.5 Lug Pattern, offset -6mm, back Spacing 4 3/4" (Bold is area not sure about) Thanks for any help.

 

Any plan on lifting? I have a 6'' lift with 18x9.5 pro comp 6001 style wheels with 4.5'' backspacing -19 offset and 325/65/18 nitto's on my ram. I know this wheel will fit fine on ur ram with or without a lift, but the tire size I am not 100% on. Need more info on what ur looking to do, there's always the front leveling kit to if you want bigger tires!1

 

No at this time I am not going to do any lift. ya I was looking at the 7089 series wheel from pro comp. I just want something taller and wider to fill in the fender well a little bit more. The stock 17's are only 7" wide. And the only other issue is speedo recal. Thanks for any advice. Never have done the after market wheel thing.

 

There is alot of wheel/tire info on the Dodge Talk forum too!!

 

The rims I have are -12 offset and 4-1/2" of backspacing. They stick out a little bit. But I don't have flares (yet). You can go up to 33" tires no problem. A few have even gone to 35's stock. The stock wheels are (I believe) +20 offset and 4-1/2" backspacing. The bigger the negative offset the farther they stick out. Hope this helps.
