First, your 07 has the TPMS so swapping will trigger an annoying indicator lamp on the dash. Wont hurt anything, but may drive you nuts.

jdruzik offered some interesting info.

Here's some details regarding the actual load ratings of the tires you're looking at vs what your FX4 has from the factory. The BFG tires shown in the ebay link, have a load rating of 2405 lbs. If your FX4 had Rugged Trail T/A's their rating was 2601, if you had the optional LT tires, Wrangler ATS, which were C range they have a load rating of 2535.

Your FX4 Screw either has a 3750 or 3900 front GVWR so any of these tires offer ample capacity.

One more thing to consider, see if a local tire shop will meet or beat this price (didn't pay attention to see if it was good or not). If you have issues with the tires, you'll be able to get it addressed quicker and eaiser at a local shop vs online. Plus, you'll be helping your local ecomony. Just offering my 2 cents.

Hope this helps.
