No sir, not a troll. Naive? Yes. I'm on this forum to learn. I'm kind of new to owning trucks. I have a 2014 Limited with all of the bells and whistles. I love it. However, when I wanted to upgrade to E rated tires, dealer and all of the well known tire dealers said that they could not suggest a tire size unless it was the factory delivered size. "Sensors might not work, might get rubbing on the wells, speedometer won't be accurate, etc.". So I got aftermarket rims and 17 inch E rated All Terrain TAs just to be safe. Clearly you folks have more experience on moving to different tires. I have heard from some of you on what to upgrade to and I thank you. As for the Ford reference, I'm sorry and I thought it would get attention, and it did. I don't want one and after doing some homework, yes I now know that all of the higher end trucks run 20 inch tires or better. So please help me out: I hunt 2 months out of the year on the worst logging roads one can imagine. The logging road graders/maintainers leave ledge and shale that tear the **** out of tires. So I need E rated all around and one underneath. And I want them all the same size. So what do you suggest when I purchase a Limited next year? What do I do for tires and wheels? Thank you for your help.
