Welcome. We have an 11 SCREW and keep the same tires/wheels on winter/summer. I tend to look for wheel corrosion but have yet to detect any. I do switch tires/wheels on my BMW, but this mostly for traction vs. fuel economy. Fuel economy is down priority list on a Raptor, like somewhere below the quality of the floormats....If fuel burn is an issue, you'll be bailing on this truck pretty soon. I typically get 12-13 around town so if your getting 10, try easing up a bit. For me? I judge that this truck was made to have fun, and fun we shall have. I don't flog it, but I am not gentle either. Take the truck off road, it's made for that, and will really prove what it's worth. A Raptor is an amazing bit of off-road engineering stuffed into incredible looking package.
