My current thought is going up to LT235/80R17 and getting a set of Michelin LTX M/S2's. Have any of y'all ever run this size tire? If so, how much trouble was it to get the speedometer recalibrated? Many thanks in advance.
Unless you tow a lot, I would stay away from LT tires. They are very heavy (killing your gas mileage) and and will ride much harsher.
I would go with a P265/70R17. It's a stock size that ford will be able to calibrate your speedo to, but it's only .8" taller.
