Wheel and Tire Recommendations:
I've Been saying for too long, "I'm gonna upgrade" well the wait is over I need tires anyway. I drive a '13 F350 SRW 8' 6.7L Upper Stableloads Super Hitch w/ 48" truss, and carry a'13 N.L. 10-2 cdse. ...

K Mac. What size wheels and tires do you currently have?
Things to consider:
With these newer trucks and all of the tubing and such in the wheel wells for the anti-lock brake systems etc, how much room do you have to safely install larger diameter and width tires? (I know I would like to know in case I ever decide to go to a larger tire.) I have a 2015 F350 XLT, and my manual states “Note: Do not use snow chains on vehicles with 20 inch wheels and tires.” I have the factory optioned LT275/70R18 tires (225 lb per tire / 450 lb per axle higher carrying capacity then the factory standard LT275/65R18 for this model). The factory 20” tires are listed as 0.9” taller and the same width as my 18's. I don't know, but the reason for not using snow chains on 20” tires could possibly be this taller diameter and clearance issues. As you go up in size in 18” tires that have higher carrying capacity, either the diameter and/or width get larger.
Tires with a different diameter then you currently have will effect your final gear ratio also. F.Y.I., below are web sites you can use to view tire dimensions and the effect on gear ratio that a tire size change might have.
I too would like to know what the Ford factory wheels are rated at for weight carrying.
