I probably should say this again...
DO NOT PUT 75 PSI IN THOSE TIRES!!! Fill 'em right to 44 and run them as long as absolutely necessary... Those tires are probably rated to about 2000 lbs/tire, as opposed to 3,000 lbs/tire...
For the rears this should get you by, but the front axle is nearly 5,000 lbs EMPTY, so they are overloaded up front...best to replace all 4 ASAP...and smack the clown that put those tires on your truck!

I've been looking online for prices so as to replace them when I get back home. Like was said earlier, I guess I'll try and sell them to offset the cost. I've got an exploreer as well but I can't remember what size skins it has on it. Thanks for "Lookin' out for me", I appreciate it. First super duty and first diesel so more questions to follow for sure.

If I were you I'd be looking to get new tires asap. From 05 on these trucks had the death wobble. I would not chance having mediocre tires on there, you're toying with your life and the lives of your passengers if you lose it.

Many owners purchase other than "E" rated tires for the SD's. If your truck never sees a load than they may be "capable" depending on their actual load range. By law and for safety reasons (as previously stated) the OEM rating should be followed. Some Tire shops will refuse to put other than what is specified on the truck. The tires you have on it may be "technically" adequate for your intended purpose but be aware. Check the actual load of the tire and don't exceede it.
Just kidding!
