Hello!!
I just purchased a 2013 FX4, and "stock" isn't my flavor. I am looking to put a leveling kit with wheels and tires on it soon, but I need the right combo so I am looking for some suggestions. I want to give the truck more aggressive stance without completely killing the fuel economy - I am looking to go to 18x9" wheels, but I don't want the wheels to stick outside of the fenders too much so the offset will need to be right....
Any suggestions on an 18x9" wheel and tire set up??? Let me know what you are working with, and post some pics!

 

Leveling is generation-specific. Moved to 2009-2014.

 

Here's the OEM 20" wheel specifications:

Wheel Size: 20x8.5
Offset: +44
Backspacing: 6.48228
43lbs each
6x135 bolt pattern

You can use this tool to observe how much different backspace, offsets, widths, and tire sizes change from the factory values.

 

I really don't think you are going to take that big of a hit in Mpgs. I'm doing a somewhat new set up with my stock fx4 rims. Really just going from 32 inch tall to a 34 inch tall. I would say if you loose from 1-2. Which is the most you will lose. You will be fine. The stance is so important in my opinion. I want to be able to look at my truck and say, o hell yes that things looks good! 1-2 Mpgs is worth it everytime. Now if you are going to try and stick some wide 35's in there. Then you will see some higher losses. Just do it bc it is inevitable. We can't stop ourselves. The forum won't allow it.

 

Mine are 20x9 with a +20mm offset to give you an idea of how much they stick out. 305/55/20 toyos

 

Looks perfect, you can run aftermarket coilovers with your stock ucas. You should talk to Alex from f150 lifts. That guy knows his stuff. I have read through all of his threads. His company is legit as they come from what I read.

I went with FOX 2.0's and BFG 285/65's. Kept the stock rims though.

 

:O)

 

I agree 100%, an aggressive stance is well worth a few MPG's!!
