If I go to carid and put in my truck info and select the coupler series, it comes up as guaranteed fit. The offset listed is +1. My understanding is that the 19s have a +19 offset. I am clueless on wheels, does the +1 mean that it is +1mm compared to factory? I want the wheels to sit as close to stock as possible when it comes to how far the wheels stick out.

the 20mm off set is closer to stock 18mm. the 1mm off set will push the rim and tire out a bit but this will give you a deeper hub face. Check on line for an off set chart. it will show you in overlap form. Wheel-Size.com I am also getting Fuel wheels on my 2015. Mine only come in off sets of 1 or 20. I will be getting the 1 offset as it will still fit in my well and give a deeper look to the wheel. The wheel I am getting has a lip face of 2.5 regardless of the offset.

Thank you Michael. I looked at that site and I am not sure if my brain is hurting worse or less. LOL I am not asking you to validate my math but if you look at the following, am I understanding the concept?

My stock wheel size is 18" x 8" with a +19.05mm offset, or 3/4". This should make my backspacing 5.25" if my understanding and math are correct. An 8" wide rim is actually 9" wide with the bead lips. 9 / .5 = 4.5 then add .75" to the positive side to come to 5.25" backspace.

If the new rim I am looking at is 18" x 9" with a 1mm offset then the math should be;
9" wide rim is actually 10" wide with the bead lips. 10 / .5 = 5 then add .04" to the positive side to come to 5.04" backspace. This would push my tire 1.21" further outward than stock (not desired).

With a 20mm offset (or .75) it would then give me 5.75" of backspace. This would push my tire .5" further outward than stock.

Spinner.. the more negative the offset the more the wheel /tire will be pushed out. the more positive offset the wheel will have less push out. If your old wheels had an offset of 19.5 and you wish the wheel to look more stock then go with an offset closer to stock.. ie 20. Note the lip of the wheel may not be any deeper between a 1mm an 20mm offset as this is fixed by the wheel design. Good luck.

Thank you. I think I am on the right track. Carid is confusing me as they recommend a 1 offset as guaranteed fitment on the Fuel Coupler though will not with a 20 offset. If I pick another Fuel wheel style, they do recommend 20. Could just be a site error. I’ll call them Monday. Thank you again.

Many after market 18 wheels will not fit over the callers even if your truck came with 18s. I tired some18 inch Ultra Warlocks and had issues. Trying to get 20s now.

I’ve seen this said a couple times but I don’t recall someone posting any issues? I am looking at the Fuel D575 Couplers, they look like they’ll work. I’ll call a couple places to be certain.

I am not doing any lift or level on my Off Road Package so 33’s are the highest I believe I can go. It does look like I could squeeze a 34” in there? but I seen someone post on their Rebel that they put the 2” Mopar lift on their truck and 35’s and he said they were close to rubbing. The 2” lift nets you 1” on the Rebel or Off Road Package from what I have read so if 35’s are close then I would think 34’s would be close on stock ORP suspension. I want a high sidewall, I just think it “belongs” on my truck so going to 20” rims won’t get me the look I want.

If you want a 9” wide wheels this is what you will want but if the front end is the same as the 4th gens you will have to be careful with tire size. For instance a 305 or 12.5 wide tire on this wheel would most likely rub the upper control arm on a 4th gen

Thanks. I’m not going crazy, just going to go up an inch, 275/65 to a 275/70 will get me the extra inch in height but maintain the 10.8” width.
