Before i order i want to make sure they are going to fit properly. I will be ordering XD rockstars 20x8.5 with 6.13 backside setting +35offset, with pro comp xtreme all terrains 305/55R20. Will be using the AS 2.5" spacer in the front and either a leaf or block in the rear haven't made up my mind yet.

 

6x135 is the right bolt pattern too right?

 

Yes 6x135 is correct

 

Should fit good.

 

I forgot to ask. what year your truck is? If it is 2004 to current the 6X135 is the right bolt pattern.

 

Good point. I also just assumed it was a 04+

 

Yeah i forget to mention its a 07, I thought i read here somewhere that someone thought that the rim with that much backspacing would rub because its sits in farther the the stock 20's i think it was PimpRohr i think that was his name....I was hoping wandell would chime in soon to ease my mind... or someone with a similiar type setup.....

 

Yah Wandell would know best. I am pretty sure I heard of someone on here running either a 20" or 22" wheel with 6.62" backspacing with no issues. I can not remember who though. 6.12 is only 5/8 inch further than stock. I would think that would not be enough to cause any issues.

 

I am running oem 20's with 305/55/20's and they do rub slightly, I'm not sure of the exact backspacing of the stock 20's but since they rub, if the rims you speak of sit in further, you will have a rubbing problem.

 

I do not know much about oem 20's or what backspacing they have. I would have thought they would have the same backspacing than the rest of the oem rims. but if they are wider than 7.5" ford may have increased the backspacing to keep the wheel from sticking out. wandell would probably know the backspacing on the oem 20"s.

 

I believe the oem 20's are 8.5 inches wide with 5.5 inches of backspacing. You will probably have some rubbing on the control arms at full steering lock.

 

if you decide to get them let us know how they fit. if those rub it is starting to make me worry I will have rubbing on the wheels I ordered and should be here any day. They are 18X9 with with 5.71" backspacing. and the tires I got are 305/65/r18's. It seems they will be closer than I thought.
