I have a 2008 screw FX4 and would like to put Fuel hostage 18x9 rims with cooper st maxx or toyo at extreme tires. The rims come as follows:
18x9x -12 offset w back space 4.5
18x9x +1 offset w backspace 5
18x9x +20 offset w backspace 5.75
The tire I want to have installed on one of the above rims is 305x70x18 or if need be 295x70x18. I will soon be installing Bilistein 5100 set at 2.25" lift with a rear add a leaf of 1.25"(maybe 1.5") and also 5100's.
Which rim tire combo would be the best to use for no rub? Has anyone used either of these tires?
Thanks for your help

 

+18mm offset is the "magic number" to go with bigger tires. Without a wide rim or wide tire to be exact. I'm about to purchase KMC XD series monster II's 18x9 +18mm offset on 34.6x11.8 tires (forgot the metric). The shop I'm getting them from said they just put 35x12.5 on another f150 and they're confident mine will fit no rubbing. You definantly need a 2.5" leveling kit for sure to do this

 

Stay away from the negative offset wheels if rub is a concern. The +18 and higher will be perfectly fine.

 

Thanks for the reply guys so I should use the +20 offset and then which tires 305 or the 295 x70 x 18?
