I'm interested in running these wheels on my 1999 SD 4X2 F250. The suspension is stock. I'm torn between the 18X9's or the 20X10's. Through some research if I ran the 18X9 I would need 4.5BS with -12MM offset and 20X10 would require 5" BS with -12MM offset. Does that sound about right? I do not want the tires pouching outside the fenderwell more than a 1/4" if possible.
I'm looking to run a 275 series tire as I pull my travel trailer with the truck and I would rather not lose my low-end torque by running a taller tire. I'm not sure if width will be a factor on a 275 series tire. I doubt it although I just wanted to get a second opinion.
I have yet to see these wheels on an F250. Please post up if you have them.
